Description:

The Pentax K-5 DSLR was developed using the Pentax K-7 as its base; the K-5 inherits the user-friendly operation, array of advanced features and compact, lightweight body of its predecessor, yet it is more resourceful with its high-speed, low-noise CMOS image sensor and high-performance PRIME II imaging engine.

The continuous shooting mode has a maximum speed of approximately seven images per second. It also offers a sensitivity range between ISO 80 and ISO 51200 (when expanded via a custom function) and Full HD-proportion movie recording at 1920 x 1080 pixels.

Other improvements over the K-7 are a faster autofocusing speed and an upgraded HDR (High Dynamic Range) function now usable in hand-held shooting.

The K-5 features a new-generation, wide-frame SAFOX IX+ autofocus system with 11 sensor points (with nine cross-type sensors positioned in the middle). The AF system has completely redesigned optics, and factors the light source at the time of shooting into its calculations so as to improve the accuracy of autofocus operation. It also offers a choice of shutter-release options - between focus priority and release priority in the AF.S (single) advance mode, or between focus priority and speed priority in the AF.C (continuous) advance mode.

The K-5 sensor is estimated to be 2-3 stops more sensitive than that of its predecessor, the K-7, meaning that a K-5 photo taken at ISO 6400 will look about as grainy than one taken at ISO 800 with the K-7.

The launch price was US $1749.95.

Pros: AF speed and accuracy, high ISO performance, build quality, price
Cons: Some of the thinking behind the buttons and their options

"Oh great, ANOTHER review?!?!" This review will focus more on why I upgraded to the K-5 from the K20D, for the benefit of anybody else considering an upgrade. I also want to give suggestions for improvement to any Pentax rep that might read this, slim though that chance might be.

But first, you need to understand that I do not tend to upgrade ANYTHING regarding technology in my life more than once every 6-8 years on average. I try to buy the best quality solution at the time so that I don’t feel the need to upgrade very often. So for Pentax to have wooed me away from the K20D after just over 3 years is saying a LOT about the K-5; I've never upgraded a camera more than once every 6 years.

PROS: What, specifically, got me to make the upgrade?
  • AF speed and accuracy. I was so surprised at the improvement that I tested this on 3 different K-5 bodies before buying mine (to be sure I wasn’t dreaming!).
  • High ISO performance. ISO 6,400 images on my K-5 are about as noisy as ISO 1,250 images were on my K20D. Enough said.
  • The beautifully quiet shutter.
  • AF.C mode. The K20D wasn’t too bad at continuous/tracking autofocus, but only in bright conditions. The K-5s AF.C mode is incredible in comparison, due again to the radical improvement in AF speed and accuracy.
  • Lockable mode dial. I found myself accidentally turning the mode dial too often on the K20D when removing it from a camera bag or when simply handling it. A much welcome return to what I was used to with film DSLRs.
  • Menu system. I can’t say that I had any problem with the K20Ds menu system, but the K-5s is even better, i.e. more refined. I love how you can still use the front and rear e-dials to quickly find the page you want instead of messing with a 4-way controller.
  • Built-in flash output. It’s so much better that I don’t have to mount my Metz 48 AF-1 as often. The one on the K20D was constantly underexposing, as was the Metz.
  • Info button, and not only being able to view info like whether Shake Reduction is on, but also being able to change it right there!
  • ISO and shots remaining showing on the top LCD at the same time, instead of just one or the other.
  • Price. At $999 CDN, I couldn’t resist any longer, especially how the K-5 is as good as/better than comparable Canikon offerings that cost much more.

CONS: What do I miss about the K20D, and/or what could the K-5 improve on?
  • I miss the Shake Reduction switch. It’s a pain having to press Info then scroll to that option to change it, or worse yet scroll to almost the bottom of page 4 of the Shooting/Record menu to change it.
  • I miss the buttons to the left of the rear LCD. From an ergonomic standpoint, the K20D had the playback and trash buttons, etc. in a much better place.
  • Info button options. It would be cool to be able to customize what you’re able to view and adjust. For example, since I never shoot in anything but RAW, the Cross Processing, Extended Bracketing, Digital Filter, etc. features are useless to me and thus they waste space on the Info screen as they only grey out instead of disappearing when you’re shooting RAW.
  • RAW/Fx button. Nice idea, lousy and limited customization options. Add to this the fact that I’ve already accidentally pressed it too many times while tilting my camera 90 degrees to the left to shoot in portrait mode. Again, it would be cool to be able to customize what options appear, including the ability to disable it!
  • ISO button is in an awkward position. On the K20D, I held down the rear OK button and turned the front e-dial to change ISO, and this felt much less awkward.

VERDICT:
  • Obviously, there’s no perfect camera, but the pros of the K-5 far outweigh the cons for me, especially the much-improved AF and high ISO performance. I also haven't mentioned a bunch of the other "little things" that I like better about the K-5. If you still have even a K-7 or older, the upgrade to a K-5 is well worth it, especially given current prices.

Pros:
Cons:
Years Owned: 2    Ergonomics: 10    Build Quality: 10    User Interface: 10    Autofocus: 9    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

LA RECENSIONE E' APPLICABILE ANCHE ALLE Pentax K5II e Pentax K5IIs (già in vendita negli USA dal 26 ottobre), salvo che per quel che riguarda l'autofocus, migliorato in entrambe (da -3Ev a + 18, che guadagna anche il tracking) e riguardo al miglioramento della nitidezza del sensore nella K5IIs (assenza del filtro antialiasing) e altri miglioramenti minori.

Premetto che ho usato e uso apparecchi di tutte le marche senza particolare predilezione per un marchio in particolare, ho comprato la Pentax K-5 ad agosto del 2011 dopo averne letto molto bene per qualche mese (possedendo già anche alcuni obiettivi professionali).

Posso dire, dopo un anno di uso abbastanza intenso (circa 12.000 scatti) che la soddisfazione é totale; mi soffermo sulle caratteristiche che fanno della K-5 un "Must" direi unico all'interno dell'intero panorama dei prodotti semipro (Aps-c o Full Frame che siano).

Inizio la mia recensione, che verrà ampliata successivamente appena ne avrò il tempo (aggiungendovi le impressioni d'uso con numerosi obiettivi di ottimo livello presenti e passati che ho avuto e che avrò modo di testare approfonditamente: Limited, Serie Star presenti e passati,Leica R, Zeiss e Universali eccellenti).

Elenco ora le qualità più salienti:

-Immediata sensazione di solidità e di tenere in mano un prodotto ben fatto che sta bene in mano ed é praticissimo nell'uso immediato, anche senza l'ausilio del libretto d'istruzioni,tra l'altro é anche un oggetto bello a vedersi e con una linea piacevole, non scontata e banale come spesso succede. Non é un caso se ho incontrato alcuni Nikonisti con fior di apparecchi super-professionali che se ne sono comprati una dopo averla "pesata" (solida lega di alluminio e magnesio e telaio interno di acciaio inox) e averne apprezzato oltre alla bellezza, all'ergonomia e alla silenziosità, anche l'eccellente qualità del sensore!

-Ergonomia funzionale eccellente, certamente migliore di quella Nikon e Canon riguardo alla velocità d'uso, alla praticità di visione delle foto scattate e al loro ingrandimento (rotella e ingr. fino a 32X !), ma anche ergonomia del design, riguardante l'impugnabilità, che ne fa l'unica reflex Aps-c di piccole dimensioni comoda e sicura da impugnare, anche con una mano sola e ancor più comoda se si usa con la soletta aggiuntiva (DBG-4) che ne migliora anche l'impugnabilità e la stabilità in verticale.

-La reflex certamente più silenziosa del mercato ed il cui scatto é molto ben ammortizzato (poche vibrazioni) in molti casi MOLTO più silenziosa degli apparecchi (anche alcuni non reflex) di altri marchi e più versatile, rendendola molto adatta ad un uso in situazioni come il teatro e i concerti e nel reportage discreto (ho usato per un po' la D7000 sulla posizione silenziosa dove pero é molto lenta e non consente le sequenze).(Per trovare un apparecchio più silenzioso, ad ottiche intercambiabili, é necessario andare sulla ottima Olympus OM-D, andando incontro però ad altri problemi (fattore di crop, ergonomia del software un po' macchinosa e minor compatibilità del sensore con gli obiettivi "terzi" non Micro 4/3 o 4/3)).

-Personalizzazione molto spinta con 5 posizioni User personalizzabili a piacere e poi richiamabili velocemente quando necessitano, nelle diverse situazioni.

-Hyper-Manual, funzione ESCLUSIVA Pentax (che visto quanto é intelligente e pratica non ho capito perchè non sia ancora stata implementata anche sulle macchine della concorrenza: brevetti? Non so darmi una risposta): questa funzione permette di usare un automatismo a priorità di diaframmi o di tempi o programmato SENZA ALLONTANARSI DALLA POSIZIONE MANUALE E SEMPLICEMENTE ATTRAVERSO L'USO DI UN PULSANTE CHE ADEGUA IL PARAMETRO RICHIESTO (io ad es. uso sempre una lettura esposimetrica Hypermanuale a priorità dei diaframmi dove, senza allontanarmi dalla posizione Manuale premendo il tasto verde ottengo l'adeguamento del tempo secondo la lettura dell'esposimetro, ma continuo ad essere in manuale, quindi sono io a gestire la situazione, con molta maggiore versatilità); questo é un sistema MOLTO PIU' SEMPLICE E VERSATILE RISPETTO ALL'USO DELL'AUTOMATISMO ACCOMPAGNATO DALL'USO DEL BLOCCO DELLA MEMORIA (ma purtroppo ancora troppo pochi se ne sono accorti!).

-Gamma dinamica eccellente e bassissimo rumore nelle ombre, ottima resa del colore (bilanciamento del bianco e sfumature di colore (14bit)).
Il sensore della Pentax K-5 (sensore Sony da 16,3 Mpx) é il medesimo della Nikon D7000 e successive e della Sony A580 e successive, ma i tecnici della Pentax non solo sono riusciti a lavorar meglio di quelli Sony ma addirittura un po' meglio di quelli Nikon (il che ha dell'incredibile): invito ad andare sul sito di DXOMark, cliccare su "compare sensors", scegliere gli apparecchi con cui confrontare il sensore della K-5 e toccare con mano la veridicità di quanto affermo (unica precauzione é di cliccare sulla finestrella "screen" e non su quella "print" per cogliere appieno le differenze tra la qualità dei sensori confrontati).

Posso dire che col sensore della K-5 quando un obiettivo era eccellente sulla pellicola (parlo ad es della serie Star o di altri obiettivi eccellenti) continua ad essere eccellente anche sul sensore, non oso pensare cosa riuscirebbe a fare ad es. l'85mm A* (star) sui nuovi apparecchi che usciranno in futuro Aps-c o Full Frame, se già sulla K-5 é a dir poco eccezionale). Posso dire comunque che anche obiettivi meno recenti (mi vengono in mente ad es l'85mm f2 M che é risultato essere addirittura un po' migliore del tanto più blasonato Zeiss 85mm 2,8 della Contax, con baionetta modificata K, o il "vecchio 40mm" che dà ancora ottimi risultati in tutte le condizioni, per non parlare di tutti i 50mm) danno risultati eccellenti. (In alcuni casi consiglio di chiudere il diaframma da 1/3 di stop ad uno stop, per via dell'abezzazione cromatica, che é un fenomeno più frequente con gli obiettivi non di recente progettazione).

Altro confronto si può fare agevolmente sul sito di DPReview (il più prestigioso sito sugli apparecchi foto a livello mondiale), cliccando su "cameras" nella barra superiore cercando la Pentax K-5, cliccando su "read review" e, all'interno della recensione completa,vedere non solo il giudizio finale (Gold Award) in ultima pagina della loro recensione, ma anche i confronti con gli altri apparecchi per quanto riguarda il Rumore nelle ombre (visionare una parte grigio/nera all'interno della foto test) : certamente il risultato migliore tra i sensori Aps-c montati su reflex (solo la Fuji Xpro1 riesce a fare poco meglio, con la differenza che non essendo un apparecchio stabilizzato, é fortemente penalizzato rispetto alla K-5 per quanto riguarda l'uso di focali fisse nelle foto a luce ambiente - io scatto ad esempio col 35mm a 1/13 di sec. o ad 1/25 di sec.col 77mm, quando con la maggior parte degli apparecchi della concorrenza dovrei usare rispettivamente 1/50 o 1/100, obbligandomi quindi ad usare una sensibilità in Iso due volte superiore (es. 1600 al posto di 400)).

Quindi quando si vanno a fare i confronti tra marchi e apparecchi diversi é corretto farli tenendo conto dei parametri d'uso nella pratica, non solo della teoria (questo significa che un apparecchio stabilizzato ha degli enormi vantaggi nell'uso con focali fisse in situazioni con poca luce e in queste situazioni riesce ad equiparare la qualità finale di apparecchi molto più costosi, ingombranti e pesanti perchè può lavorare ad una sensibilità ridotta di due o tre stop rispetto a questi!)(Solo la Canon tra le grandi se n'é accorta e ha fatto uscire un 28 e un 24, ora anche un 35/2, stabilizzati ma molto costosi).

-Altro pregio della K-5: le performance, la capacità del buffer é la migliore nella sua categoria: riesce ad es. a far meglio della Nikon D7000 (riesco a scattare di seguito 23 Raw+Jpeg alla massima risoluzione) usando delle Sandisk Extreme da 30Mb/s (la D7000 é un po' meno performante, anche se si usano le molto più care Sandisk Extreme Pro da 95Mb/s).

-Ha una Tropicalizzazione completa (resistenza a pioggia, polvere/sabbia e neve) e funzionamento garantito fino a -10°C (unico nella sua classe di prezzo, ma anche meglio di molti appercchi professionali) che significa poterla usare in pratica fino a -25°C senza timori: io l'ho usata personalmente a -20°C tenendola sempre fuori dallo zaino senza problemi, con l'unica avvertenza di portarsi dietro 1 o 2 batterie di riserva se l'uscita é molto lunga.

-L'autofocus infine é molto buono con tutte le ottiche nuove (in alcuni casi eccellente), può creare qualche problema di lentezza con alcune tra quelle più datate originali o universali; mi riservo di approfondire la questione appena avrò un pò di tempo da dedicarvi; (non faccio foto sportiva) certo quello della Canon é mediamente un po' meglio; dalla sua la K-5 ha comunque la personalizzazione dell'AF come le reflex di livello Pro (ad es. posso dare la prevalenza allo scatto rispetto al fuoco anche con l'impostazione dell'AF su Single, così da non perdere mai una foto).

-Si possono montare tutti gli obiettivi anche quelli più vecchi (anche quelli a vite) continuando a fruire dell'esposimetro (Manuale, HYpermanual, Priorità dei diaframmi, Esposimetro Spot e a Prevalenza centrale e Conferma della messa a fuoco nel mirino); per usufruire dell'esposimetro tipo matrix sono necessari gli obiettivi dalla Serie A in poi; con la K-5 però, rispetto alla K-7 precedente, é stata di molto facilitata la lettura anche con i vecchi serie M o K) (per le ottiche a vite la lettura esposimetica e la conferma della messa a fuoco nel mirino (led verde) avviene senza necessità di chip aggiuntivi sull'anello adattatore) e anche usufruendo dello stabilizzatore (é la macchina che chiede quale focale impostare per la stabilizzazione (degli obiettivi a fuoco manuale) senza dover andare ogni volta sul menù, come succede invece su apparecchi di altre marche (vedi Olympus OM-D).

Consiglio vivamente (salvo che per chi porta gli occhiali) l'acquisto dell'oculare ingranditore originale O-ME53 che aiuta nella messa a fuoco manuale (con un po' di perdita di qualità ai bordi, ma sempre migliore del corrispettivo Nikon per D7000, tra l'altro molto scomodo) e che ha anche una gomma ancora più confortevole (e bella ) dell'originale (già ottimo).

In definitiva una macchina così completa e ben fatta da risultare eccezionale e di cui é facilissimo innamorarsi, tra l'altro é anche un oggetto piacevole a vedersi e con cui in molti settori ci si può tranquillamente lavorare; tra l'altro in questo momento viene venduto ad un prezzo molto contenuto se consideriamo il suo valore concreto e con il miglior rapporto qualità prezzo di tutto il mercato;(lo dico con cognizione di causa avendo usato con costanza diversi apparecchi miei e di amici, Aps-c , Full Frame e con Sensore 33x44mm). Considerata l'alta qualità della macchina ne raccomando così vivamente l'uso soprattutto con obiettivi di qualità eccellente.

Aggiungo, in considerazione dell'alta qualità del prodotto (e ancor più delle nuove K-5 che stanno per uscire) che conviene acquistarla con una Garanzia seria e possibilmente con estensione della Garanzia a più anni, perchè questa é una macchina che si tiene per diversi anni dopo averla apprezzata come merita.

Pros: Build, size, speed, low light, quiet, IQ, fps, etc etc
Cons: Ermmm, I struggling here....okay "only" 16 zone metering, AF is still not quite as good as "the others" but close
Years Owned: 9 months    Ergonomics: 10    Build Quality: 10    User Interface: 9    Autofocus: 8    Features: 10    Value: 10    Image Quality: 10    Noise: 10   

How do I compare this camera? Do I rate it compared to all my other Pentax DSLR's I have (*istDS, K10D and K20D) or how it performs against other DSLR's that I have played with or borrowed from friends (which means anything from a Nikon D300, D7000, D90 to the Canon 5D, 5D mk2, 7D, 1D's mk3 and 4).

Okay then, lets gof for the former first - how it compares to my other Pentax DSLR's.

Well, it is practically the same size as my DS (so small then) and smaller than my K10D/K20D bretheren. It is also magnesium bodied, rather than (good quality) plastic of the others. The grip? perfect! Menu's - completely different. It was a little confusing at first, but I have soon got the hang of them. Shutter? So quiet and no slap recoil that you get with the older models.

Okay, against the rivals I have used. Well the AF is still noisy with non SDM lenses, but seems a tad quieter than older models. AF speed is far better than in the past, but still a bit slower than CaNikon, but it is more accurate.
High ISO performance. Well, what can I say? It MONSTERS the Canon ISO and then some. Only the Nikon D3s trumps it, and I am being serious here.
I have taken shots at 25600ISO and they have been more than useable (something you cannot say about the 1D mk4 that I have used)

Colour rendition - Very accurate, even in auto. Still not quite as good as the punchy K10D, but far better than the K20D, even in RAW.

Would I recommend it as DSLR? Oh yes and then some! It is the finest DSLR Pentax have made, and in a lot of respects, exceeds the performance of other DSLR's many times more expensive. Pentax should be proud!

Pros: IQ, build, handling, value for money, size and weight (or rather lack of)
Cons: Slow processing
Ergonomics: 9    Build Quality: 9    User Interface: 9    Autofocus: 8    Features: 10    Value: 10    Image Quality: 9    New or Used: Used   

UPDATE FEB 24.

The K5 continues to astonish me in regard to its IQ. For an APSC sensor with AA filter, I see no resolution difference when compared to my 16mp Fujfilm XTrans 2 sensors on X-T1 and X-T10. Also for an APSC Pentax sensor I am finally able to get B&W images I am pleased with. Colour images to ISO 3200 and B&W to ISO 6400 look good with pleasing noise.











Since purchasing my K1 ii a couple of years ago I have been using my KP and K3 cameras less and less but still wanted a camera for casual use. I tried out a Canon 6D partly for curiosity's sake and as they are ridiculously cheap these days and I was impressed with the old AA equiped sensor. Curiosity further aroused I wondered what the old 16mp sensor of the K30/50/5 cameras IQ was like so I did some exploring online and discovered that the cheapest option was the K5, a copy of which I picked up for just under £200 including a battery grip and just under 1400 shutter count. What a bargain!
Overall the camera is very nice indeed. It's just a little bit smaller and lighter than either the K3 and KP with their battery grips fitted and very surprisingly fits my hands even better than the truly awesome K3 in this respect. The build quality, handling, user interface all seem typically Pentax. In other words very good indeed. The AF also seems typically Pentax - ie. a bit ho hum and clunky but fine for single point single shot AF. In this regard my copy seems to focus in half decent light as quickly and as accurately as either the K3 and KP. The only negative I can find in the overall usage of the camera is the slowness of the image processing. I have been taking many practice shots to get used to the camera with various lenses and chimping as a consequence. It can seem like quite a few seconds pass before you can review your images. In normal use this would not bother me as I generally do not review my images immediately after taking them but it is something to be born in mind. Overall though I like the handling, interface and functionality of the K5 more than that of the K3 (a very close 2nd) and KP (3rd)
Image quality is very nice indeed. Note I say nice not excellent or some other superlative. When compared to either the KP or K3 the look is distinctly different. The 16mp with the AA filter is clearly lower resolution at lower ISO settings, but it still provides more than enough for 16"X20" prints which is as large as I am ever going to print, even with a bit of cropping. Get beyond 800 ISO and I reckon it produces better images than the K3 and almost as good as the KP. This is a highly subjective view but the very slight lower resolution looks more natural to my eyes than that of either of the two more modern cameras. On a purely objective view I would rate the sensor output as first KP, second K5 and third K3.
I am blessed with a number of digital cameras. Apart from the aforementioned K1 ii, K3, KP and Canon 6D I have a few Xtrans II Fujifilm cameras. For my serious "work" I will always choose the K1 ii. For B&W one of the Fuji's, but for a casual walk about camera the K5 with either a 28 or 35mm lens and a 50mm macro will increasingly be my choice. Even with the battery grip it's not too heavy, large or indiscreet. It feels great in my hands. The IQ is lovely. When considering the price what more could one ask for? Highly recommended.

Here are a few of my favourite snaps so far - taken with the F 50mm f2.8...

Pros: Ergonomy, HI-ISO, Live View
Cons: AF accuracy, flash exposure, material quality
Years Owned: 12+    Ergonomics: 9    Build Quality: 8    User Interface: 9    Autofocus: 8    Features: 9    Value: 9    Image Quality: 9    Noise: 9    New or Used: New   

I bought K5 new in 2011 after having K20D. Camera evolved a bit over time as new firmware updates were released over time. First batches had various issues with AF, which was later addressed by those FW updates a bit. But some issues stayed forever like moody low-light AF, moody AF with fast lenses and flash overexposures. My body also had issues with lens release button that fell-off twice, but luckily during warranty. Another quality issue was rubber grip, that came off and even service was not able to fix it properly, so I had to peel everything off, clean both camera body and rubber grip and then using hi-quality 3M double sided tape I attached it back and it holds since that for over 9 years now. Another failure is rubber material on camera connector port cover/door. It completely disintegrated after about 6 years. And also MIC JACK plug disintegrated years ago. Shutter button half-press started to behave strange after about 8 years. If we forget these fails, the rest of camera is built like tank. Mine served me well for over 9 years and I took about 130 000 pics with it until I added one barely used K3 body in 2020. K5 is now in cabinet with K20D both being back-up bodies and for occasional multi-camera setup use.

K5 was significant improvement over K20D mainly in AF speed, hi-ISO noise, 8 FPS, Live-View with contrast-detect AF and obviously FHD video. I skipped K7 as it was very little improvement over K20D. Ergonomy is also very well designed.

16 Mpix Sony sensor was a beast and images are very clean up to ISO800, still very usable with ISO1600 and when exposure is nailed and some resize is acceptable, then even ISO3200 is OK. For downsized pics like 3000x2000 even ISO6400 is OK. All from RAW. It outperformed all competitors when K5 was fresh on market and even today it is still not lacking too much.

Autofocus on good light is very fast and quite accurate. Only fast lenses like F1.4-F2.8 sometimes have issues with random BF/FF. But with lenses like Sigma 70-200/2.8 HSM II even some birds in flight were possible. AF-S of course. AF-C is only usable on slow moving targets.

Live-view has nice feature of enlarging the selected point during operation which I miss on current K3 body. LV AF was the only option to achieve good AF results with lenses like FA50/1.4, FA35/2, Sig35/1.4, Sig17-50/2.8, Sig18-35/1.8 etc because phase detect AF with such fast lenses was not very accurate especially with low light and tungsten light. LV AF operates even with dark setups like Sigma 50-500/4-6.3 with attached 2x Teleconverter.

Flash photography basically requires full Manual mode to be used and then camera and flash behave OK. But in any auto mode like Av, TAv or P the cooperation with P-TTL flash is one big problem as camera tries to use MAX ISO all the time and then overexposures the picture unless you force about -2EV correction on flash and camera. The good part is, that it has pop-up flash that can be used as wireless flash commander for external flash units.

Camera also has Astro Tracer tool, which was added through FW updates later. It needs O-GPS hot-shoe unit, but it works well.

FullHD video is nice on paper. It is usable, but many compact cameras can capture significantly cleaner and less compressed video files. K5 can use SR during video, but it is a bit laggy and it adds mechanical noise to video.

Sad part is, that K5 is not fully compatible with latest KAF4 lenses like HD DA55-300, DFA*50/1.4, DFA*85/1.4 etc because it cannot operate aperture without lever.


Is K5 a great camera? Yes and no, it has its issues. But it is true workhorse that served me for many years and I do not regret the price I paid for the new body. 130k pics, 9+ years of daily use.. and it still works. I used it for everything, it worked in rain, it worked in caves, it worked on weddings, it worked during journalist part time jobs, it worked in university laboratory and of course it captured countless trips.

It was a big milestone camera for Pentax and best-seller of its own league at that time reaching very high numbers. I cannot remember seeing any Ricoh/Pentax cameras introduced later so much often. K100D, K10D, K20D, Kx, K5 and K50 were used widely.

K5II and K5IIs introduced later were just partial improvements so I had no interest in those. And even K3 had initially so many issues, that I kept trusty K5 for many more years. Then Ricoh focused on K1, next APS-C KP was disaster, Pentax was almost removed from market and when my K5 started to be more and more problematic with disintegrating parts, I simply bought the K3 original as it is closest camera to K5 still with pop-up flash, almost same ergonomy and almost all bugs solved over years with FW updates

Pros: Great IQ and rock solid body
Cons: awful AF in tungsten light, awful C-AF, noise reduction on RAW files at high ISO
Years Owned: 4    Ergonomics: 9    Build Quality: 10    User Interface: 8    Autofocus: 4    Features: 8    Value: 8    Image Quality: 10    Noise: 7    New or Used: Used   

The K-5 is a great DSLR, but it has a few flaws that could be a deal breaker for some users.

First, the ergonomics are almost perfect, with most of the buttons and controls being in the right place. The main issue is having to press the "OK" button to switch between selecting the AF point and changing white balance, picture style, etc. The AF point should've had a dedicated button. The built quality is exceptional for a camera in that price range, being able to rival pro DSLRs with ease. I never had any issue when shooting in rough weather (from the good old Canadian snow storms to the remains of a hurricane, i.e., pouring rain with winds gusting at 110*km/h) with Pentax's weather sealed bodies. I only wished the viewfinder was slightly brighter (or bigger), but it is quite satisfactory as it is. The shutter is rather quiet, especially when compared to the K10D.

I don't use most of the K-5's features, but the ones I do use seem to be just awesome! I wish my OM-D E-M1 had some of these features, like the green button, which is perfect to meter a scene using lenses with no electronic or mechanical contacts to the body. One area where the K-5 lacks features is the video mode. It 's very basic and should be okay to capture memories like family moments if used correctly, but don't expect much beyond that.

The image quality (in RAW—I never shoot JPEG) is also exceptional at low ISO, with great dynamic range (I easily can recover 3*stops in shadows and a full stop in highlights in post-processing at ISO 80-200) and well-controlled noise level up to ISO 1600. I just wish Pentax had removed the antialiasing filter on the K5 to get the best IQ possible. Still, the AA filter isn't too "strong," so the IQ remains great with sharp lenses.

Unfortunately, the IQ degrades beyond ISO*1600; it's still very good at ISO 3200 and good to very good at ISO*6400 (beyond that, it's only "usable," no more). Still, the noise reduction clearly takes it tolls on image quality above ISO*1600. I don't understand why Pentax decided to apply so much luminance noise reduction on the RAW files of the K-5. I wouldn't have minded some chroma noise reduction, but so heavy luminance noise reduction is just a bad choice on a RAW file, as that specific noise would be handled much better in post-process.

Autofocus is fast and relatively accurate in AF-S (depending on your lens) in good light. Like my K10D and my K-7, the K-5 back focuses with all my lenses, even when using in-camera AF micro adjustments. The accuracy isn't a problem when shooting with a decent depth of field. When trying to achieve a shallower DoF, however, the AF is very often off target. That said, it was only really noticeable when shooting at apertures F2.8 or wider and at focal lengths 50mm and longer, and it happened mostly in low light. So...I learned to stop down my 50-135mm to F3.2-3.5 to achieve better focus. Still, that AF inaccuracy ruined many of the shots I made at wide aperture.

Worse, the camera constantly front or back focuses in tungsten light. I only learned this recently, but it probably explains why so many of my indoor pictures were slightly out of focus. This problem is only is a known issue of the K-5, one that couldn't be corrected with a firmware update, so Pentax "solve" the problem introducing...the K-5*II. (Learning this prompted me to jump ships, which I did in December of 2018.)

Now, all the above was only for the AF-S and, quite unfortunately, the C-AF is not better. Shooting a subject coming at me a low speed (like someone jogging), I never was able to get 1*picture in focus out of a 10*images burst. The C-AF seems to struggle equally in good or low light. The lenses I used (DA12-24mm*F4, DA16-45mm*F4, DA*16-50mm*F2.8, DA*50-135mm*F2.8, and DA50mm*F1.8) aren't known for their blazing speed, however, so maybe my experience would've been better with another lens.

I mainly used the camera for documentary and architecture photography and to shoot stage events, and I was usually very happy with the results. The only moments I raged at my camera were when it wasn't properly focusing. Not all stage events rely on HMI 5000*K lights, unfortunately. Bottom line, the K-5 is a great camera that delivers great IQ in a solid package. It's the perfect package for outdoors and streets photographers.

Pros: Feel in hands and control locations
Cons: filters and cross processing
Years Owned: 0.2    Ergonomics: 10    Build Quality: 10    User Interface: 10    Autofocus: 10    Features: 4    Value: 5    Image Quality: 5    Noise: 10    New or Used: Used   

I have purchased the K-5ii and 2 k-5's in the last two months the most expensive was the most recent a k-5 for $318.00aud previous a k5 for $165.00aud and before that a k-5ii for $275.00aud.

Buying these cameras s/h one would expect the cameras set up with filters and the cross Processing and the contrast well its not the case the camera's I purchased had the features switched off and the only reason I can think these features are so poor for me is the fact the camera is made in japan where the cities are bright with colourful lights etc. The colours in the cross processing are wrong eg green over blue -wrong. Red over purple wrong if you change those colours or better still add to them you would have a far better camera and why not add more filters in the cross processing as they are just filters I had a beautiful sunrise the other day because my k5 is blan photo wise I tried cross processing and it covered the beautiful colours and added filtered colours that just look plain wrong for the natural enviroment. Photo's of holidays are taken in the more natural enviroments and to exclude this a mistake. Adam a few posts back I said your image on the soocer field was really good which it was but it had the red white and blue karma about it where as it should have been colourful but on more earthy tones. My km takes better photos and also my istd than the k-5's I have and these are older cameras than the k5 everyone is saying bigger image quality and forgetting the colour quality in saying that I do not mean bright colours there are plenty more colours than red white blue yellow.

My next attack in on the =/- ev adjustment at 0 (zero) all my cameras in the k-5 range are overexposing why is this have you forgotten how to set up the ev meter. I have to take a number of test shots to set the camera up each time I go out why because the camera is too sensitive I don't know why if you set your sensitivity it should be set. You shouldn't even have to set it in an ideal world you should just be able to grab your camera walk out and take astonishing images and upload them to the computer but this would be too easy we have to make it hard for the average Joe and let the photographer work hard to keep his identity as a photographer if those little phone cameras can take a good quality image why can't the k-5. There are some of you that will say I am shit at taking photos but with my istd and k-m I take better photos what does this mean for the k3 and the k1 will they be worse? When you look at a scene we all view it the same way and if its stunning naturally the camera should record this with all settings in the zero position.

I am self taught then went to tafe and got a certificate 4 when I taught myself I concentrated mostly on the taking a photo side of things as I wanted to be able to take an excellent shot every time. Today i had a slightly positive result with my most recent setting but the very best setting for a camera should be no special settings at all then you work from there. I'm not blaming my camera I'm blaming Ricoh for making the camera too complicated to use and forgetting their roots. -- well its not too complicated its just the settings for Ev and their filters are wrong and insufficient Possibly there could be an update with more choices in cross processing. Also a setting menu added like the k-m's one for colour and exposure or an method and also a setting to correct the incorrect ev meter somthing like the fine focus adjust. I think I found this in the form of the user settings not what I had in mind but its workable.

I love the iso range 80 to 51,200

Why don't these cameras have a list of the last 5-10 changes made in the camera so you don't have to search all the menus. also make them selectable and have the previous settings in sub menus so you can go back quickly.

I would like ti say at the moment there is a revolt against digital images being edited recently on the News a Model or actress was sueing over edited photos and I think this is a good thing as editing photos becomes art and not photography and a camera should be designed for Photographers that want an honest photo.

Well I just found a heap more settings to play with will be interesting to see the results I get with these once set. This is rather annoying having so many places with different settings these settings I found are saturation hew shados etc the ones on the four way arrows so this is possibly where there are some incorrect settings that I will need to correct.

Just found out how to use the user mode and learn't about the green mode While this is good it is extra complications Guess I'll be chompin at the bit to get some photo's. To think I have three of these to set up.

I am really starting to see a huge benefit owning K-5's one will be set up for sunrise and sunsets another for landscapes (natural & domestic) and one for water sports and each. Actually thinking it over Natural will be on each camera But still those filters are still all wrong and need extra.

Photography used to be a simple pleasure.

Pros: Quick and accurate AF,Very good auto exposure,intuitive and flexible controls,good (and tested) weather sealing, batterygrip,excellent battery life
Cons: Zoom lens a bit noisy during focusing

After owning and using a Pentax IST DS, Pentax K10D, Pentax K20D it was a really Progression for me.

A really good product. The high ISO performance is impressive (until to 3200). The stabilization is good, the product is really robust, not too heavy and not to big, with mounted battery grip good balance and energy reserve. This product is a little bit "old" (2010) but always good for a casual or enthusiast photographer

Pros: Build quality, external controls.
Cons: Software (menu system, playback). Not the best LCD.
Years Owned: 1    Ergonomics: 9    Build Quality: 9    User Interface: 6    Autofocus: 8    Features: 10    Value: 9    Image Quality: 9    Noise: 9    New or Used: Used   

Cross posting this review I originally wrote on the K-30, with some edits, since it's a direct comparison between the cameras:

Let my share my experience with the K-5 as compared to the K-30, as I own both cameras. Owned a K-30 from the start. Then I also got a pretty beat up but perfectly working K-5 body very cheap, since I was interested in trying out a camera with more external controls

After extensive use, I've made a list of pros for either camera, ranking each feature with one to five stars in accordance how important it is in my shooting (which may of course differ from yours...)

In my use as an amateur, IQ (*****), viewfinder (*****) and autofocus (*****) differences are academic at best between these two cameras (I know the K5 is 14 bit compared to 12 bit for the K-30 but for me that isn't an issue).

K-30 Pros:
***** Much more responsive software, better info pane layouts.
**** Markedly brighter, sharper and clearer LCD
*** Faster write speed to SD card.
** Better layout of play/trash/liveview buttons minimizing risk of hitting the wrong ones during operation.
** No lock button on the shooting mode wheel makes it easy to operate one-handed with the right thumb

K-5 Pros:
**** About twice the battery life
*** Battery grip can be added
*** Better placed green button making for faster action when stop down metering manual lenses
** Metal body as compared to plastic (My K-30 actually creaks a little when the grip is pressed firmly!)
** Better placed loops for the camera strap makes the whole camera very well balanced, especially with longer/heavier lenses
** Dedicated well placed ae-lock button
** Pretty quiet shutter
* Electronic level in the viewfinder
* easier to access stop down switch to check dof (this can be set to the raw button on the K-30)
* Top panel LCD
* Dedicated physical controls for af-mode and metering mode
* control wheels have a bit larger diameter making their haptics more enjoyable.

Actually I was a bit surprised after getting the K-5, I thought I'd be shooting it exclusively leaving the K-30 at home. As it turned out I actually prefer the K-30 in daily use. Much boils down to software: Before getting the K-5 I hadn't reflected on how much you interact with the cameras playback and menu system: and how annoying it is when these aren't as responsive as you're used to. The duller screen was a turn off as well. Before getting the K-5 I also thought I'd be using the external controls more but as it turned out it didn't save much time compared to changing settings in the info pane.

Conclusion: In amateur use It's hard to find a better bang for the buck these past years than the K-x0 series. K-7/5/3 are nice bodies but you pay a very high premium for a metal body, a few extra knobs and switches and the ability to use a battery grip. I tried a cheap chinese grip which worked fine, but also made me realise I don't need one in my shooting. The K-5 will soon be up for sale, sticking with the K-30. Cheapskate as I am I will be very interested in picking up a lightly used K-70 a couple of years down the line when I feel it's time to upgrade.

Pros: Low Isos, High Iso, Low noise, Fast AF, Image Quality, A step forward
Cons: AV mode not taking great photos
Years Owned: 1    Ergonomics: 9    Build Quality: 6    User Interface: 9    Autofocus: 9    Features: 10    Value: 10    Image Quality: 9    Noise: 9    New or Used: Used   

I bought my K5 in Japan, in a second hand store with a low milleage in photos taken and in perfect conditions for 250€.
At the time it was a bargain as you could find it in Europe for 450€ body only.

This is definitelly a step forward from a Kr, and i am delighted with that machine. It is a semi-professional camera (or some say so) with manual controls everywhere, no more automatic modes that you don't need anymore, and plenty of buttons easy to undersand and well located.

I love the camera because it's light, compact, easy to carry around and because of it's performance. I usually shoot at racing cars, and it's TV mode and its buffer are great for action sports, and at 7fps I think it's pretty great, now I am not missing a photo.

The AF is quite better than Kr's for me, and it's a step forward in quality, in sharpness of the image, sounds better when shooting, it's not a noisy machine as the Kr can be, it is great in high ISO.

The sealed body is awesome, I have been shooting at snow places, during rainy days and at very dusty events and you can be sure non of those would get inside your camera, wich to me is a great step forward.

Combine this camera with the smc Pentax F 50mm f1.7, or the Sigma 100-300mm F4 and you'll get SHARP SHARP SHARP images, as you always dreamed about. I believe it's sensor, and the camera itself improve those lense's qualities to an outstanding level.

The only awakeness point is the AV mode, or I don't get it right, or the camera uses to over expose my shots constantly.

It is true that it's AF can make you miss some shots, but wich Pentax camera doesn't?

Overall it is a great camera, and nowadays that prices are lowering down, just get one at a great price, you'll get a bargain on an great piece of camera,





UPDATE June 2016
After having had the camera for almost 2 years I have to say I was delighted with it, maybe not with the AV mode, it's not as good as I expected it to be, but a part from that it's all great.

Just mine decided to fall down a chair and the repair work costs almost as much as I payed for the camera, so I am a bit disapointed on the body, as it really was a small and slow crash. So I think maybe my unit has had another crash before (in Japan) or maybe the body is a bit weak.

Pros: Image quality, ease of use, User modes
Cons: Button layout could have been better, more

The best image quality on ASPC in my eyes. The weight and the way this camera feels in your hand is just perfect. The user modes is simply genius as it allows me to program my settings for landscape, portrait, action, tripod for quick access.

I believe the button layout could have been better. I don't like where the AF button is and the RAW button could have had a few more options.

I would give 9.5 but alas not allowed here.

The best Pentax camera ever. The newest K3 is nothing compared with this K5 of 2009. Maybe and maybe because i don't believe they will create one, but maybe one day Pentax FF can beat the K5. Even lots of FF from other brands are nothing compared with Pentax K5

Pros: Build quality, IQ, ergonomics, low-light performance
Cons: AF speed/accuracy, a few minor ergonomic quirks.
Years Owned: More than one year    Ergonomics: 9    Build Quality: 10    User Interface: 9    Autofocus: 7    Features: 9    Value: 10    Image Quality: 9    Noise: 9    New or Used: Used   

This is my first DSLR--and my first autofocus SLR--after a few years shooting almost exclusively with classic film cameras (Pentax, Konica, Olympus OM, and Nikkormat SLRs, plus Canonets, Konica Auto S2, Kodak Retinas, Yashica-Mats, etc.). I learned a lot of photography basics, and picked up some nice K-mount primes in the process--hence my decision to go with Pentax for my first DSLR.

Bought my K-5 used from KEH, after figuring out that the it had the same sensor as the K5II/s, and the same build quality/weather sealing. I thought this would be the best compromise between cost, IQ, and build quality for a second-hand DSLR. (And it arrived looking like new from KEH, with a very low shutter count.)

I shoot mostly candids, street, architecture and abstracts, mostly in natural/existing light. (I don't really need the faster autofocus of the K5II.) And this camera delivers: fantastic dynamic range, great colors--once you find a good camera profile--great ergonomics, and all in a small, rugged package.

I'm used to shooting family/friends with a small rangefinder camera, something I can disappear with into the background. I find the K-5 a little more obtrusive than what I'm used to--a little bigger, a little louder, a little more technical--but of course it's a quiet and meek as a mouse compared to other DSLRs. But it turns out the K-5 is great for candid photography, especially when coupled with one of Pentax's primes. And the low-light performance makes f2.8 fast enough.

I'm still getting used to the control-dial interface. I'm more accustomed to anticipating the light and pre-setting my cameras using shutter/aperture dials that I can see at a glance; having the top panel LCD is helpful, but not quite the same. (The Fuji X-T1 is looking very good right about now!)

One annoying quirk: toggling the arrow buttons between shooting settings and focus-point selection; it's not always easy to figure out when it's switched from one mode to the other.

Wish list: better AF with faster lenses, maybe focus peaking (implemented in successor models, I know), a better solution for manual focusing. (I cut down an old Konica focusing screen for use in the K-5, but I'd prefer it if Pentax had a better microprism screen available for working with their legacy fast MF primes.)

EDIT (September 23, 2014): I've had the K-5 for more than a year now, and have shot ~30,000 frames. I'm mostly shooting with Limited primes these days--the DA 21mm f3.2, the DA 35mm f2.8 Macro, and the 70mm f2.4--and I'm left a bit dissatisfied with the autofocus implementation. I shoot a lot in low light and in natural light, and I'm finding the K-5's AF doesn't quite deliver the goods with faster lenses. I've tried fine-tuning focus, updating to the latest firmware, etc. Sometimes the K-5 nails it, sometimes it doesn't. (It has particular problems discerning a dark subject from a lighter background; daylight outdoor shots of my black dog often end up mis-focusing on the background instead.) But often the only way to know if you've really nailed focus is by looking at the shots on a monitor later.

I'm thrilled with the sensor's low-light performance and dynamic range, happy with its 16mp resolution, and love the K-5's build quality and ergonomics. (The more I use it the more at home I feel with it.) But now I'm considering upgrading to a K-5II or K-5IIs to see if I can't wring more consistent performance out of my Limited primes.

Pros: Fast and easy menus, great image quality, weather proof, easy to customize.
Cons: No manual video mode, no tether without 3rd party software.

Got the K-5 as my first DSLR. I've been shooting film SLR's for 3 years prior to this purchase and, besides my old Pentax ME being my favorite, I chose the K-5 for the weather proofing and compatibility with my already owned lenses, features that I couldn't get with any other manufacturers.

After 15 months with this camera, I can't see myself switching to any other brands. I've shot other cameras from friends, but apart from very few advantages, it's still tough to beat the "bang-for-your-buck" Pentax offers.

The weather proofing and the in-body Image stabilization (the later allowing for any old K-mount manual lenses to be used without any hassle), work flawlessly. My first day with the camera outside it survived a quite decent amount of rain with it's kit lens, and it didn't take me more than 30 minutes out to learn all the little tricks the K-5 offers and switch to manual mode without second guessing myself.

The video quality is good, but I do miss manual video exposure. It can be done but needs some working around, and even then you can't really switch any settings after you start recording.

Image quality blew me off right away. The amount of dynamic range in the RAW files is extensive. To be fair, I never really shot any JPEG's to be able to compare to anything else, but even at that, the camera let's you customize the jpg output for sharpness, contrast, saturation, hue etc... quite easily (1 button to be exact).

Besides those, you get all of Pentax's goodness: in-camera HDR, auto-bracketing up to 5 exposures, interval shooting for time lapse, in-camera RAW processing, filters, 5 custom user modes, microphone input, really long battery life, 100% view finder coverage, a full-range of weather resistant accessories, fine focus adjustment profiles, etc.

In my experience with the K-5, I gotta give it a 9.5 out of 10 at the very least.

Pros: Ergonomics, Weather-Resistant, In-Body Stabilization
Cons: Mediocre AF performance, stabilization could be a lot better
Years Owned: 2    Ergonomics: 9    Build Quality: 9    User Interface: 6    Autofocus: 6    Features: 7    Value: 7    Image Quality: 8    Noise: 8    New or Used: New   

In-Body Image Stabilization is a blessing at times but quite often it's underwhelming when compared against the best Optical Image Stabilization lenses available for Canon/Nikon. The K100D had an external switch to turn stabilization On/Off but the K-5 requires menu diving which is a pain. Any time you're not in a good shutter speed range to benefit from stabilization, images are usually sharper with it off, sometimes dramatically sharper.

No problems with single-AF on static subjects but then any camera can do that. With only 11 AF points, Continuous-AF on moving subjects is nowhere near as good as Nikon's 39 or 51-point AF systems with predictive tracking.

Resale value is hardly a Pentax strong-point either. On the plus side, it's well-built (except for the lens-release button which a lot of people have seen fall off), it feels great in the hand (except for the stiff/sluggish weather-resistant buttons), and the viewfinder is large, bright and 100% coverage.

The K-5 is a good enough camera but whether it's the best one for you depends a lot on whether your needs coincide with the camera's strengths or it's weaknesses. Personally, I detest Nikon's frequent rendering of reds as orange so that's a huge hit against Nikon for me. Canon's cheap-feeling plastic bodies with poor-ergonomics and often sketchy AF means that only their high-end professional and semi-professional models hold any appeal. Canon and Nikon have impressive lens ranges but that does me little good if I can't afford them. With Pentax, there are some remarkable yet affordable lens options: DA55-300, DA40, DA70, Tamron 28-75/f2.8 and 70-200/f2.8, and the Sigma 10-20mm f/4-5.6 (all stabilized to some degree).
