Pentax K-1


The Pentax K-1 is the first full-frame Pentax K-mount DSLR to reach production. After a year's worth of teasers from Ricoh it finally hit the market in February 2016. The K-1 continues the trend from the K-3/5/7 series of being a photographer's camera with a user friendly layout, superb handling in a relatively compact form factor, and a feature set targeting the serious photographer.

The K-1's key features:

  • Full-frame CMOS sensor
  • 36.4 megapixels w/ 15-megapixel crop mode
  • Pixel shift super resolution
  • No AA filter
  • AA filter simulator
  • Sensitivity up to ISO 204,800
  • Shutter rated for 300,000 actuations
  • Electronic shutter as an option in live view shooting mode (requires firmware update)
  • 5-axis sensor-shift stabilization
  • Redesigned viewfinder with LCD overlay
  • 6.5 FPS in crop mode, 4.4 FPS in full frame mode with up to 100 JPEG buffer
  • LCD screen tilts and pivots
  • LED illumination of lens mount, buttons, and card slot
  • Dust & weather sealed
  • Built-in GPS and Wi-Fi
  • USB tethering support as well as tethering via Wi-Fi

The K-1 viewfinder has an LCD overlay with a customizable grid, crop area indicator, and dual-axis electronic level. The grid can be enabled or disabled via the menu, as can most of the other features of the overlay.  A dedicated light illuminates this overlay on demand. The viewfinder has 100% coverage and a 0.7x magnification which makes it a tad bigger than the viewfinders of the APS-C format cameras.

The pixel shift capability has been improved over the K-3II in that the K-1 will attempt to correct artifacts stemming from moving objects.

The shake reduction feature has also improved and is now rated good for 5 shutter steps compensation.

The K-1 has no anti-alias filter in front of the sensor. Should moiré be an issue the K-1 includes the unique Pentax feature of an AA filter simulator that works by vibrating the sensor ever so slightly during exposure thereby reducing or eliminating moiré. The simulator has three settings (off - weak filter - strong filter). An AA simulator bracketing mode is available.

The body is made from magnesium alloy surrounding an inner steel chassis.

The K-1 was launched alongside two new full frame lenses: the HD D FA 28-105mm F3.5-5.6 budget-friendly kit lens, and the HD D FA 15-30mm F2.8 ultra-wide zoom.  These lenses supplement the recently-launched HD D FA 24-70mm F2.8, HD D FA* 70-200mm F2.8, and HD D FA 150-450mm F4.5-5.6 full frame lenses.

All current and legacy K-mount lenses are compatible with the K-1. M42 screw mount, 645 and 6x7 lenses can be used with the appropriate adapters. With DA K-mount lenses the camera will shoot in a 15 MP crop mode with the active area outlined in the view finder. The crop mode can be overridden which is useful in connection with those DA lenses, that perform well on full frame. Among these are the DA* 200mm, DA* 300mm, and DA 560mm lenses. The K-1 even offers lens correction for these three lenses when they are used in FF mode.

Read our in-depth review of the K-1 here.

Major features subsequently added through firmware updates:

  • Version 1.50: Optimized performance with the D FA* 50mm F1.4 lens
  • Version 1.41: Support for the enhancements introduced with the Image Transmitter 2 version 2.3.0 software
  • Version 1.40: Night mode (red light) for the rear monitor; bulb timer function
  • Version 1.30: Electronic shutter as an option in live view shooting mode; 1:1 crop mode; 2 frame AA filter bracketing
  • Version 1.20: Support for lenses with KAF4 mount, i.e. lenses that have foregone the mechanical stop-down lever
  • Version 1.10: Support for the Image Transmitter 2 version 2.2.0 software; support for tethering via an Adobe Lightroom plug-in

Review Date: January 22, 2019 I can recommend the Pentax K-1: Yes | Price: $1,500.00 | Rating: 10 

Pros: Ergonomics, FF, IBIS, Weather Sealed, High ISO, Direct Control
Cons: Centralization of AF points, AF speed, Articulating screen
Years Owned: 1 month    Ergonomics: 9    Build Quality: 10    User Interface: 10    Autofocus: 7    Features: 9    Value: 10    Image Quality: 10    Noise: 8    New or Used: New   

Coming from a K20d the K1 is a huge leap for me in everything except the learning curve, most buttons and controls are very similar so I've found myself completely at ease with this camera. On first unboxing I was concerned because there was a definite shifting of something within the camera, I later found out that this is normal. That was a scare as I bought the camera from an ebay retailer (but authorized Pentax dealer), but it still worried me. I bought the K1 new instead of the Mk II due to some issues raised by DPReview, if this camera interests you on the used market you might read that review. Anyhow here are my thoughts on some aspects of this camera.

1. Build Quality is superb - What I've come to expect from Pentax/Ricoh.
2. Ergonomics - great, maybe not as good as my K20d, but I don't have the battery grip yet. If you don't think this is important, I have a Nikon D5000 gathering dust you should talk to.
3. IBIS - Easily 4-5 stops of stabilization, superb! Coupled with the high ISO, most flash situations are non-existent with this camera. Hence, no pop-up flash needed!
4. Size is large but not really much bigger than my k20d!
5. 3 command dials and 2 function dials and button inputs!!! Awesome, no menu diving for basic functions. Camera is a joy to use, especially if you grew up with film cameras.
6. Quieter and quicker by far than K20d.
7. Great to have an articulating monitor, I've missed that. It is something I used to use often.
8. The viewfinder is super, I can focus manually again. Wish they came with split/microprism focusing screen though.
1. Why not have a flip and twist monitor?? My Coolpix 8700, Oly E-3, and Nikon D5000 (kinda) had it, but the K1 has a strut system. Better than nothing, but still, what's the deal?
2. All the AF points are in the APS field of view. This to me is just stupid, I'm constantly having to recompose to get the composition I want.
3. Slow AF. My first "good" DSLR, the Oly E-3, stomps the K1 ... ELEVEN YEARS LATER!!! If only Oly hadn't used the 4/3 sensor.
4. Slow FPS continuous shooting... not a deal breaker, but again the 11 y.o. Oly beats it.
5. Slow write-to-card speed and buffer clearance. Also, if you switch cards around it can cause issues with the camera.

The only issue to me that is truly a big problem (for my picture taking style) would be the centralization of focus points. Then again, I've used cameras with only 3 FP's! No negative is so great as to detract from the whole in this camera.

As always, even from it's earliest film days, Pentax is a camera for photographers who appreciate value, quality, and core photographic needs. This is not a video camera, it is not a do everything but nothing well camera. It is a superb photographic machine. Bravo RICOH!!

P.S. - I have not tried the astrotracer or pixel-shift yet so no comment on those abilities but really am looking forward to trying them out soon.

Review Date: December 27, 2018 I can recommend the Pentax K-1: Yes | Price: $1,190.00 | Rating: 9 

Pros: FF Pentax! 36MP, Weather Sealing, Astrotracer, Composition Adjust, IBIS
Cons: AF, Video Mode, limited selection of modern lenses
Years Owned: 1    Ergonomics: 9    Build Quality: 10    User Interface: 10    Autofocus: 7    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: Used   

The Pentax K-1 is my body of choice for still photography where you can take your time. The featureset and resolution is simply unmatched at this pricepoint, and is a long-awaited gift for those of us who love the character and "personality" of Pentax's vintage glass without the hassle of shooting film.

I won't say much about ergonomics because it's so subjective. I love the addition of the variable dial, tilt screen, and comfortable grip. I would have liked to see a dedicated AF point joystick and alternative placement/design of the remote trigger socket - it gets in the way of adjusting the camera on a tripod, and my trigger tends to fall out quite often.

The build quality of this camera is second to none. Comparing this camera with other major brands - Nikon and Sony come close but Canon is definitely coming in at dead last. The overall body construction, materials, and weather sealing on this camera is incredible, especially at this price point. The minute you hold one in your hand, you will know exactly what I am talking about.

The UI of this camera is not for everyone, but allows the user an incredible amount of control over the camera overall. Some people may prefer a more simple interface, but I don't mind a bit of digging when there are this many features available in a "budget" FF body.

The AF on this camera is nothing incredible and one of the reasons I really hesitate to recommend this body to the uninitiated. Pentax knows their market - it works fine, but is far behind the competition with the incredible features of Nikon's Continuous AF, Canon Dual-Pixel AF, and Sony's Eye AF. The AF on this camera will serve you well, but is a definite drawback from the Pentax system - if you are looking for a sport or action camera, I'd recommend you look elsewhere. Stills - it will work well.

The featureset of this camera is the #1 reason I decided to invest in the Pentax system. As a still photographer shooting landscapes, waterfalls, and abandoned buildings, this camera has more to offer than the other "Big 3" combined. My favorite features on the camera the others can't offer in a single package:

- Built-in GPS tagging (I like to drive around and take pictures of whatever I like - this feature lets me return to a location effortlessly. Why don't the others include??)

- Tilt Screen!! Until the D850 (released shortly after purchase for 2-3x the cost) neither Nikon or Canon have offered a serious FF body with a tilt screen.
Ridiculous - it's incredibly useful for all types of shooting at difficult angles. While quirky, I love Pentax's implementation

- Best in class Weather Sealing - exploring dusty, abandoned mines, snowy mountains, dirt trails and waterfalls - this has never failed me

- IBIS makes all of your vintage lenses stabilized - perfect for those who love the character and rendition of old glass

- Astrotracer feature works wonderfully (most of the time ) for astro and landscape shots! Unique to Pentax, at least for FF.

- Pixel Shift for even higher resolution. Notably doesn't work well on moving subjects, and doesn't always play nice with Lightroom/PS.

- Composition Adjust!! This feature is commonly overlooked for some reason... in a matter of 2 minutes and 4 shots, flawlessly stitched in post - you can simulate a
46MP, medium-format-ish sensor. Simply shifting the sensor to the 4 corners allows you to cover ~26% more area with a wider FOV and higher resolution from a
single perspective with 0 parallax errors or other issues, besides possible vignetting.

The value of this camera speaks for itself. It is easily the best choice for still life photographers, and comes at such a cheap price. Perfectly functional used bodies can be found for $1200- on feeBay.

IQ is also top tier, with a sensor matching that found in the D810, the IQ and Dynamic Range is easily on par with the best Canon, Nikon, and Sony have to offer. Noise is incredibly low and with Pixel Shift on a static subject, I would say it is easily the lowest-noise FF camera on the market.

So why would anyone buy anything besides a Pentax, you might ask? Well, a lot of reasons. Firstly, as stated, the AF on this camera is nothing special - functional, but not impressive compared to the competition. Secondly, the video capabilities are nothing short of embarrassing. If you want a video camera, this is not the one for you - look at Sony a7s series.

Third, and I would say most important, is the relatively tiny selection of modern, FF, AF glass for a 36MP system. Pentax has covered its bases with the DFA 15-30mm, 24-70mm, 70-200mm*, 150-450mm, and 50mm*. Not to mention the lovely limited lenses and those high-quality DA lenses that work perfectly on the FF sensor, including many DA* primes and the DA560mm. Additionally, the cost gap grows wider when considering the used market, as the Big 3 have many lenses of years past available for relatively cheap, including Sigma and Tamron support. But wait! Pentax has supported the K-Mount for 40 years, you say. There's countless lenses in the K, M, A, F, and FA series supporting a FF image circle! I can already hear my fellow Pentaxians screaming bloody murder as I criticize the FF lens lineup. As someone who absolutely adores vintage glass, the cold, hard, truth is that 98% of those old film lenses are simply "not enough" on a 36MP sensor. While there are MANY notable exceptions, most of that stuff was designed for film resolving the equivalent of around 8MP, not a modern 36MP sensor. Not to say that they should be immediately forgotten, but the point stands that lens selection is a huge drawback for the Pentax system - something I think Ricoh understands and is working incredibly hard to remedy.

Overall, this camera is second to none for people willing to take their time to get the shot. I love using sharp old glass such as the K 135/2.5, A 50/1.7 or M 28/3.5 without the hassles of shooting film. There is a certain indescribable quality about vintage glass that makes me love it, but as someone who also loves large prints - you need to choose wisely. few of the beloved Takumar/Pentax lenses stand up to digital quality standards.

Review Date: December 24, 2018 I can recommend the Pentax K-1: Yes | Price: $1,500.00 | Rating: 10 

Pros: Image Quality, Full Frame, Ergonomics, Dynamic Range, Build Quality
Cons: 4 frames per second burst and buffer speeds
Years Owned: 3 months    Ergonomics: 10    Build Quality: 10    User Interface: 10    Autofocus: 9    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

I moved up from a K5 IIs to the K-1. I had owned the K-1 back in 2016 but the copy I received had some quirky issues that caused me to return it during the trial period. This copy of the K-1 I am reviewing is perfect. I was able to pick up with the grip, sling bag, 32GB SD card, software, cleaner, pentax strap, and other goodies for the amazing price of $1497 delivered! From a value standpoint, i would rate it a 15. The camera has a great weight to it and is combined with great weather sealing.

The K-1 has been rock solid since the unboxing. I updated the firmware and started shooting. I was amazed at the image quality produced from all of my lenses but especially my 77mm limited, 31mm limited and now the most impressive 50mm * 1.4. The combo of the the 50mm and this camera body is out of this world. Every lens I place on the K-1 renders amazing photos. I have 3 sigma lenses that rally benefit from the 36MP: 100-300mm F4 (FF), 70-200mm ff2.8 (FF), and 18-35 f1.8 (APS-C). Without any post editing, the images are spectacular. The best implementation of Sony 36MP sensor with amazing dynamic range.

I have been a Pentaxian for 7 years and have to say this camera is exactly the full frame camera I was waiting for. In my hand I feel the possibilities are endless. With the movable rear screen, the camera is an excellent choice for any landscape photography shoot. With the improved 5 axis image stabilization, photos come out razor sharp even when hand held in average to low light.

If I had to list improvements that would entice me to upgrade in the future, it would be more cross type focus points, improved frames per second count (at least 7 in ff), 4K video (even though i don't use for filming), improved buffer performance, and continued improvement on autofocus algorithms. While I am not a sports photographer, these upgrades would make the Pentax full frame, the ultimate full frame. However I would add that anyone who purchases the K-1 couldn't possibly be disappointed. This is an amazing camera that should be able to take me through the next 8 years of photography.

What everyone says about the K-1 is true. I have no idea how I can outgrow this camera. I highly recommend the K-1 for any person who loves photography!

Review Date: November 24, 2017 I can recommend the Pentax K-1: Yes | Price: $1,990.00 | Rating: 10 

Pros: Full Frame, tropicalized, shake reduction, many lens available even for low budget, great high isos, handling,
Cons: for the moment nothing
Ergonomics: 10    Build Quality: 10    User Interface: 9    Autofocus: 10    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

I already have Canon 5D classic, Sony A7 and Kodak Pro 14n, and I wanted to get a full frame by Pentax, the K1 was and is the obvious answer to me.

I had it for $1990 as special offer and also taken official battery grip for increasing handling in portraits shooting and also using my Eneloop AA batteries.

For the moment I am deeply satisfied and will share some pictures very soon.

If you have the basics and really need full frame, you will be happy with K1, however avoid lenses as 28-300 and so on, use constant aperture or prime lenses. For sure if you are low budgeted when once bought K1, 50 1.7 or 1.8 are great choices or take a 35mm, choices are numerous.

Review Date: November 1, 2017 I can recommend the Pentax K-1: Yes | Price: $1,896.00 | Rating: 9 

Pros: Image quality, dynamic range
Cons: Heavy
Ergonomics: 9    Build Quality: 10    User Interface: 9    Autofocus: 8    Features: 10    Value: 10    Image Quality: 10    Noise: 9    New or Used: New   

I've been using my K-1 pretty constantly since May, primarily for landscape and birding at the moment, stepped up from the K3. All in all it's an excellent camera, a great value for the money. And compared to the big name competition, you can't beat the quality or features for the price. The image quality is excellent, the dynamic range is amazing. I love the unique flippy LCD screen, it saves my back a lot of pain, long overdo.

The ergonomics are as always with Pentax gear, excellent. I'm still getting used to using the third control wheel. Not sure it adds a lot, though I am getting spoiled being able to change ISO on the fly. So I guess it is possible to teach an old dog some new tricks. No complaints for more choices.

Auto focus is very good generally, not as good as I'd like but what photographer was ever satisfied with autofocus

The external illumination is an amazing feature. Was very very happy to find that feature. My only wish is that they could be switched red LED's too.

I primarily use the D-FA 24-70 and the D-FA 150-450, along with the FA-31, FA-77 and FA 100 Macro F/2.8. Most of my other lenses are going unused. I'm anxiously awaiting an ultra wide angle prime from Pentax (20mm range) in order to round out my kit. I'm finding the FA Limiteds to be wickedly sharp on the K-1 body.

My only negative, is that it's heavy, though with a full frame sensor, I wouldn't expect otherwise. Combined with the D-FA 150-450, and it's a work out, especially when shooting birds in flight.

I'd recommend this camera, without hesitation, to anyone looking to move from their current APS-C kit to full frame.

Lastly, my hat is off to Ricoh for being a proactive and excellent steward of the Pentax brand.

Review Date: October 12, 2017 I can recommend the Pentax K-1: Yes | Price: None indicated | Rating: 9 

Pros: Image quality, build quality
Cons: not really designed for big hands, thumb rolls onto the four way controller when using the camera in any mode
Years Owned: 1.5 11700 images    Ergonomics: 5    Build Quality: 10    User Interface: 8    Autofocus: 8    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

I have owned this camera from new. I use the 24 - 70 zoom,the 70 -200 zoom and the 150 - 450 zoom.I also own the 28 - 105 zoom. They all perform amazingly well with the K-1.

I have bid hands, 2XL in gloves, and get really pissed off when my fingers roll onto the four way controller part way through a shoot. this is my only criticism, other wise the camera and lens combinations mentioned above really sing. ( see foldedrat on flickr)

Would I buy another? Just as soon as my K-3 dies.

I really like this camera and will super glue some sort of extra relief for my thumb on the back, whenever I remember.

4. Tough magnesium allow body.

5. Sturdiest implementation of movable rear screen.

6. Third control wheel to allow more manual control.

7. 5-Axis in body image stabilization. All lenses are image stabilized.

8. Pixel shift mode gives better dynamic range and details than medium formats.

9. In built GPS.

10. Two SD cards for data backup.

11. Astrotracer uses GPS and floating sensor to allow longer sky exposures without risking star trails.

12. Floating sensor allows automatic horizon correction.

13. Floating sensor also allows anti-aliasing filter mode in case you are running into moir.

14. In built Wi-Fi.

15. 14-Bit Adobe DNG Raw files, so all software versions can open it.

16. Supports APS-c lenses in crop mode.

17. Led lights to help change lenses, look at buttons in low light.

18. Finally can use the coveted Pentax Limited lenses on a full frame cameras.


1. Only 25 out of 33 focus points are cross types.

2. Slower focusing as compared to other full frame flagships.

3. Inaccurate tracking focus.

4. Not as many full frame modern lenses from Pentax.

5. Not many lenses from third party. Sigma has stopped supporting K-mount.

6. Focus points do not cover the whole picture frame, concentrated at the center.

7. Video is least impressive. Doesn't support 4k.

8. Doesn't support mechanical image stabilization for video (yet).

9. Slow clearing of buffer even with fastest memory cards.

10. Below average battery life.

Review Date: December 27, 2016 I can recommend the Pentax K-1: Yes | Price: $2,200.00 | Rating: 10 

Pros: dynamic range, build, ISO
Cons: non

Amazing dynamic range with this camera. What always has been difficult to reproduce are images of the sky. If you shoot in RAW, you will be able to get all these different shades of grey of the cloud formations. It seems to me that is was each time really the sky I photographed. That is an new experience to me .

ISO is impressive as well. Indeed, no more flash needed. I live in an apartment which does not get a lot of sunlight and sun goes down always early in my country. So shooting indoors was often an bad experience for me. AF problems, IQ flash was always needed. But I do not like to shoot with flash. It ruins every picture. Makes it looking artificial. Sure there are a lot of techniques like bouncing flash-light and filters but .......I do not care any more about that. I can shoot now in very low light conditions. So cool ! ISO of 12000 or 25000 is usable.

I did not tested features like ASTROTRACER yet, but this will come soon

WiFi works fine. Your camera will be the "server" where you have to connect to, if you like to get your pictures quickly onto your smart phone. Some free app from RICOH is needed therefore. Worked fine.

And as always, veeery good interface, handling and ergonomics with PENTAX.

I am an very happy K-1 owner but I have to admit, it is my first full frame camera.

Ongoing review

At last, a Pentax full frame digital camera. Nice.

Dimensions are small for a FF camera, but significantly larger than APS-C. All Pentax lenses presented along with the K1 are also large. You cannot easily switch from APS-C to FF. I came to Pentax for the compact dimensions of the K5 with lots of DA prime lenses.

That said, K1 feels rock solid even with DFA 70-200 - also without battery grip. Perfect size for hand holding. For travelling I will have to get used to size and dimensions. The camera fits perfectly in your hands even when walking.

AF is not improved over K3 and focus area only covers APS-C area. It works, it is OK, it can follow some faster action, but it is not a K1 highlight. High-ISO performance is also great and much improved over K3(s).
Pixel shift resolution is great, 36 MP is amazing, 5 stops SR s great, performance in general is great. K1 uses standard Pentax batteries, so I already have spares.

I am still missing a possibility to save user settings. It would have been nice to transfer settings from K3, ... or save K1 settings on disk for later use. The new quick selection wheel has some benefits, I mainly use it to switch crop mode while still working with APS-C lenses. APS-C lenses in crop mode make for decent panoramas and often some more area with dark corner is more important than no coverage at all.
Viewfinder has no blinds and the plastic cover cannot be fixed on the carrying strap. I am missing an inbuild flash, but I am also happy with the current size.

Review Date: June 30, 2016 I can recommend the Pentax K-1: Yes | Price: $1,799.00 | Rating: 10 

Pros: sensor, ergonomics, WR, af, shake reduction, pixelshift, wifi, screen, gps, size, price
Cons: none
Ergonomics: 10    Build Quality: 10    Autofocus: 10    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

After two months usage and more than 20,000 actuations this is my conclusion :

It's flawless and it's the best deal FF camera on the market today.
It has a great amount of available new and used full frame AF Pentax & third party lenses and a huge number of full frame manual lenses to cover all possible professional needs.
In terms of ergonomics, it is the best full frame 35mm DSLR ever created.
In terms of autofocus, i've never imagined i could use a camera with 80 to 100% AF succes rate, depending of the lens attached.
The screw driven AF is fast enough for 99% of the needs. The SDM AF is fast and ..silent! enough for 99% too.
I won't talk much about everything else that i find perfect and covering the 99% of top notch full frame photographer's needs.

The 1% downside is the shots/sec rate. Do not forget that Pentax doesn't have a line of sport specific cameras like Canon and Nikon that aim high shooting rate. But what you loose in high end sports photography with this one, you gain in studio shots with the pixel shift technology, and you get yourself the cheapest medium format equivalent quality possible.

Review Date: June 23, 2016 I can recommend the Pentax K-1: Yes | Price: $1,796.95 | Rating: 9 

Pros: 36 mm x 24 mm sensor size, intuitive controls
Cons: Chunky appearance, no pop up flash
Years Owned: <1    Ergonomics: 9    Build Quality: 9    User Interface: 10    Autofocus: 9    Features: 9    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

Here’s the reaction of one older photographer who cut his teeth on a 1960s era manual everything (including aperture) Pentax 35mm SLR, who has shot digital since 2005, and is adding a K-1 to a photographic stable which until recently was headed by a K-5. With a little luck, it'll slice the pie in a different enough way from other reviews to provide just enough new insight to help someone with an upgrade decision.

Things I don’t like:

- The body style. It’s chunky, and the biggest body Pentax has ever offered in the 35 mm SLR form factor, albeit smaller than its current competition. It does fit my hand well though, and as at least one other person has mentioned, my pinky fits on the grip instead of having to go under the base plate.

- The loss of the pop up flash. It’s something I use fairly frequently with other cameras to control off-camera flash, and the removal of this convenience is an annoyance. Some have rationalized the camera is more professional without the popup, but if professional is the aim, how about removing the clutter of the Auto and P modes from the exposure mode dial? I suspect it’s more a matter of physically fitting guts into a space-constrained shell, and as such will deal with it with no further complaint.

- The change of of the metering mode switch from a lever under the exposure mode dial to a selection button. The physical lever is simple and direct, the button a little more complicated and less direct. This was apparently introduced with the K-3, but this is the first time I’ve experienced it.

Things I like:

- Faster, quieter, surer focusing, in dimmer ambient light than the K-5.

- Insane low noise sensor sensitivity.

- Use of the same battery as the APS-C cameras.

- The rear display. It’s wider and clearer than the K-5, and of course, articulated. I don’t have an opinion of the mechanics other than I wish it would tip down further for overhead shots. More about this in the WiFi comment. I use focus point selection a lot, and the way the 4-way controller is depicted on the display in different modes is WAY better and more intuitive than the K-5 and previous models.

- GPS. Geotagging images is an extremely useful capability, one I’ve grown to love for snapshots on my iPhone. There’s also an option to keep a separate log file of periodic position updates for trip/expedition records, if you don’t have another means to do so.

- Wi Fi. Not sure why it can’t be used to connect with computers for file transfer, but it will connect with mobile devices using the Image Sync app. Using the capability to synch images to my iPhone is something I’ll probably never use, but the ability to use a smartphone as a remote control is a great feature. There is a remote viewing capability which could probably be used to overcome the inability of the articulated display to point directly downwards, along with other obvious uses. Exposure settings can be made in accordance with the exposure mode set on the physical camera dial, as well as selecting focus points. The green button is also available as well as a quite responsive virtual shutter release button.

Using Image Sync to control the camera appears to work only when the shutter is in single shot mode, and you should be sure it’s set that way before connecting the camera to the phone. While the app can be a little finicky, the actual WiFi connection seems quite robust and reliable, connecting quickly and easily, and maintaining the connection to at least 30 feet or more.

- The controls. They’re close to a direct transition from the K-5 (and even closer for a K-3 as far as I can tell). The changes seem to be a change for the better.

— The viewfinder diopter adjustment is a dial like on the K-3 rather than a slider like on the K-5 and previous models. Much easier to use.

— The addition of the smart function dial. Unlike some reviewers, I see it as a real plus, giving direct physical or alternative access to 9 settings. As I use the camera more, I may have reason to quibble with the functions chosen by the designers, but overall it’s an improvement over the K-5.

— The addition of all 5 user modes to the exposure mode dial. This is a step up from the innovative but awkward 1 user position on the mode dial on the K-5 and 3 positions on the K-3.

— Making the MF/AF switch a two-position switch. It was always awkward selecting single AF vs. continuous AF from MF without directly looking at the switch. Now you can go between MF and AF easily, and change the AF mode as needed with a separate control. This is apparently featured on the K-3 too.

— Moving the focus point selection mode change function from the OK button to a separate button above the 4 way controls. Quicker and less ambiguous for me.

- I didn’t buy a DSLR to do video, but I appreciate the addition of being able to focus with the AF button as needed while video is in progress. I also look forward to having the ability to adjust audio recording levels. Again, these features were introduced to the Pentax lineup with the K-3, but they’re new to me as they would be to anyone else upgrading from a K-5 or earlier body.

- Focus peaking. Very cool feature which highlights in-focus edges in live view. Another new to me but not K-3 users option.

- 36 mm x 24 mm full frame sensor size. As a person raised on 35 mm film, putting a camera with a full frame sensor to eye quite simply feels like returning home. Lenses have the proper field of view, and although subtle, have the proper depth of field.

— My 30 year old A 24 mm f/2.8 lens didn’t get much use on my other digital bodies because it didn’t offer much, if anything over the DA lenses I had. It’s a different story on the K-1. Although at similar magnifications it’s similar in performance to my DA 15 mm Limited, it completely blows the 15 mm out of the water when used to provide a similar field of view. It’s not a knock on the DA lens, which has to work in a much more stressful setup to provide a wide field of view in a smaller image, but is a clear demonstration of the advantages of the full frame sensor size, especially for wide angle lenses. For telephoto lenses, it’s pretty much a wash, because even if there’s a wider field of view in full frame for the same lens, you can always manually crop for the same performance as APS-C, or even set the camera to capture in APS-C mode (even with an FA lens).

— 36 MP is nice, but not necessary for a lot of photography… it’s the actual physical sensor size which makes the biggest difference for me with the K-1. I expect that at least one of my user modes will involve a lower pixel count capture setting. That being said, being able to print a 33” x 55” enlargement directly from the image file is nothing to scoff at. And the difference between really good and magnificent lenses will be more obvious than ever!

— The FF/APS-C mode implementation is slick. For lenses, you can choose APS-C, Full Frame, or Auto modes, the latter setting automatically choosing the effective sensor size based on whether you’re using a DA or FA lens. When in APS-C mode, the viewfinder displays an outline of the area that will be captured in an image. I expect to continue getting full use of my DA lenses when they make sense, particularly in the transition period where I’ll be filling in holes in my full frame lens stable.

Bravo to Ricoh for keeping the Pentax tradition alive, and for introducing such a masterpiece as the K-1. It’s a bit humbling to have to say this, having been a Pentax snob who wouldn’t have given a Ricoh camera or lens the time of day in 1975!

Review Date: June 13, 2016 I can recommend the Pentax K-1: Yes | Price: $1,799.00 | Rating: 10 

Pros: Image Quality, Consistent Performer, Solid Build, Weather Sealing, Value
Cons: Video
Years Owned: .4    Ergonomics: 10    Build Quality: 10    User Interface: 10    Autofocus: 9    Features: 10    Value: 10    Image Quality: 10    Noise: 10    New or Used: New   

Full review here.

Growing K-1 500px gallery.

K-1 perks from review listed here:

K-1 perk 1) Stellar spec sheet on par with the best full frame cameras available today. Getting the well knowns that separate it from the rest of the Pentax clan out of the way in one perk. 36MP, full frame, 1/8000s shutter speed, and improved 5-axis image stabilization. Few cameras operate in this company.

K-1 perk 2) To add on to the Pentax perk above it has to be said again. Price. Until the K-1 was released the full frame camera I wanted most was a Nikon D810. No more. At $1,000 less not only does it match the D810 spec sheet it keeps going offering features no other DSLR I know of offers regardless of price (Cameras like the Leica SL baffle me what you get for what you pay wise, but much respect to those who can afford them.) like GPS and image stabilization and…

K-1 perk 3) Built in WiFi. Above not only many of it’s siblings, many other DSLRs like the D810 either do not have or require a dongle for this. Of note the D750 has WiFi, but priced above the K-1 it has 24MP, no IS…

K-1 perk 4) 3rd control wheel of many purposes. Agreed they went crazy with the choices, but that control wheel has been fantastic in use.

K-1 perk 5) A ‘unique’ tiltable screen. I will be first to admit that it seemed wonderfully over engineered to me initially (I am an Industrial Engineer by degree you understand). But in use this is what it is about. My preference is flip down/up screens (E-P5, E-PL5, NX300, NX1, RX-100ii for instance) and central to the K-1 screen is this type of mount. No sideways motion with those above however. Side 180 degree swing out and swivel screens (NX30 for instance) are less discrete when used as a waist level viewfinder and have an inherent single point failure point where the screen meets the camera. So what if you want a bit of sideways view action, but with more anchor points? Mount the up/down tilt mechanism to the camera using an interesting rods with sliding ball socket mechanism that works as billed.

K-1 perk 6) LED access lights. Brilliant. Why has no one else done this?

K-1 perk 7) Full frame. Unique to the K-1 this makes the K-1 so much more usable with the 28-75mm and 70-200mm ranges of the 2 Tamrons mentioned above. On the K-3ii the crop factor was not a plus making the 70-200mm too tele for in a pinch walkabout use.

K-1 perk 8) Low noise and image quality on par with the best cameras out there. This cameras performance far outshines the full frame film and digital cameras I have used and my only real IQ comparison can be made with my 2 medium format film cameras. And I am talking about normal mode. Pixel shift mode provides even greater results where the shooting situation allows. The image quality is that good.

I may add perks if more come to me, but these are more than enough in my book. It is my sincere hope that Pentax can get these in to as many hands as possible. It may not convince die hard brand loyalists to switch. I understand. A lot, emotionally and fiscally, goes in to choosing and building a system. But if you have only APS-C bodies and lenses you owe it to yourself to take a look if you have been thinking of moving to full frame. Same applies if you are looking to start off new with a full frame. If you have found yourself with a full frame body, but like I did you now realize you cannot bring yourself to spend the astronomical sums companies, factory and 3rd party, are asking for primes and image stabilized constant aperture zooms consider this: Backwards legacy lens compatibility and the availability of non-stabilized 3rd party constant aperture zoom lenses means I have spent $100 less for a new K-1 ($1,799), 3 legacy primes ($149), and 2 used zooms ($750) combined than the current new price for a D810 ($2799) body alone. A trade could go a long way is all I am saying.

Well, been using it for a month now and it's a sheer joy to use. The image quality and dynamic range is just stunning. Have tested around 20 lenses of all ages this past month and even with old Pentax-F zooms it delivers fantastic images but it's most impressing when putting on old Zeiss Jena lenses or my Limited's (35 & 70)

My K-1 is still on v1.00 but I have not encountered any bugs yet.

Update 17-07-25:
Been using it for more than a year now and still love it !! Have not encountered any bug either.. The only negative, but not a big one, is that one still can't tell the K-1 what memory card it should use besides pulling one out..

Cons: Ummmm, don't know

The sheer feature set, value for money and feel of a true piece of hi tech in your hands just puts a smile on your face...........

The unfortunate thing for me is not yet having one of the new lenses, but the trusty FA's are helping me out in the meantime, especially the old FA 28-105 f4-5.6 IF seems to be doing a good job.

The write speed, shutter feel / sound and operation of this machine is sublime, leaving the aps-c's in it's dust and the write speed of K3 looking sad.

With older FA's I feel the image quality compared to good glass I have on my K5iis/K3 is not always a massive step but even with the 28-105 when it locks ... yes still noticeably detailed and sharp.

Using my FA's even sounded different ... they don't grind, they squeek, a much better sound, lol

Unsure if it was me, or the old lenses but I felt that hand holding even wide angles at low shutter speeds i.e. 1/60th @ 28mm left me with a little blur whereas I can easily do this with the K5IIs at 12mm .... Further investigation required as a handheld night shot at 1/2 sec yielded a better result. This was something I noticed going to the K3 ....... K1 has same pixel density as K5, so .......

The wifi, astro tracer, gps, pixel shift, 5 axis stabilisation, tilt screen and 36mp sensor with the auto crop capability just packs so much into a body its unbelievable. As one who does a few weddings, landscapes, portraits and low light / night photography ... WOW !!! I can see Pentax gaining a few more pro's and serious users again.

Interface is pretty much the same and you know where to look for the new features. A few buttons in different places on the back but that's been juggled around over the years and i'm ok with that.

Will take some time to get the full use and knowledge of all the features, but basic use is just another world.

Congrats Ricoh for being bold enough to go there ... it's going to be a winner, another classic and a game changer that along with 645, K3 and new lenses is about to start Pentax brand back along the slow journey to credibility in the photography world ......
