Good analysis. But you forgot to mention: no lenses ;)
FF is a big commitment for pentax, lets just hope that Ricoh will give founds for this!

I just said that its harder to build UWA for aps-c dslr. Of course they exist but they are not as good as the ff or mirrorless ones (at least the ones that I tried).

done. and I don't like it both. I do like the panasonic 7-14: mirrorless. I do like the zeiss 18mm: fullframe. Try before buy :cool:

Yes, 35mm is the must have, but we need also ultrawide. And we need also telephoto but not supertele: that's for sports and nature.
1) normal
2)wide
3)tele
4)ultrawide
on ultrawide FF has a clear advantage

What about wide angle lenses? its easier to build wide and ultrawide lenses on FF and on mirrorless aps-c. That's why I think aps-c on dslr is technically a bad idea. Image quality is just ok but reportage photographers that needs at least a ultrawide lens will go on FF or mirrorless, and the amateurs always follows what they see in the hands of professionals..
Pentax wake up!!!

k-5 freezed a couple of times, i think because of the full buffer-slow write speed. that has never happened with Cf equipped cameras.
I've lost some data because of broken SD cards sometimes, and at least once a week one of my clients comes to me asking to recover fisicaly broken sd cards.
You can't smash a CF so easily.

Thinks I don't like about k-5
- SD cards :slow and less secure than CF
- zoom lenses not comparable with the opponents
- No FF. I know there is the MF 645 but its not the same thing

Glad you enjoyed my thread, I'm encouraged to do some more considerations about k-5 usage (I think is not the case to open a new thread):
I don't know if this is because of the dynamic range, but the prints from k-5 are very pleasing, rich, tridimensional. A pleasure to print in fine art baryta paper at 16-bit. Specially black and white have really something more!
Thant makes me even more angry for the lack of FF! Imagine what a FF sensor with this technology can do! Please Pentax don't let Nikon easily win this match!
Image stabilization: here I would like to know your experience, because it sounds very strange to me:
IS works very well till 1/40 but very badly around 1/80. I don't know if that is a mirror slap issue o something like that, but a lot of shots from 1/80 to 1/125 are strangely blurred, while a lot of shots at 1/25- 1/30 are perfectly sharp.
Same thing for you?

Glad to read a lot of replies!
@Raybo: thank you! I'm very proud of that, but I must say google translate helps a lot. :D
Regarding the lens: Yes I suppose the 16-50 f/2,8 is better, but not a lot better (et least on paper). Moreover I think the Canon's opposite is not the 24-105 but the 24-70 f/2,8 which I can assure you is a lot better than the 24-105. Not to mention the Pentax 50-135: If it exceeds the Canon 70-200 f/2,8 I would be really impressed.
Regarding Sensitivity: 5DmkII is no (more) impressing. Its about one stop better than k-5 and 5DmkI. The gap varies depending on sensitivity, but generally around one stop till 1600 (my limit of safe usage).

Here is my first thread:
I would like to share my thoughts about the Pentax k-5.
Why that should interest you? Well... just because I'm a obstinate Canon user!
[DISCLAIMER: 1)This is not a scientific test! This is just a milkshake of personal opinions based on my everyday work as event and reportage photographer. You'll not find any picture to pixelpeep. 2) I'm italian and I learned English from hollywood movies, forums and instruction manuals, so please be good.]
I work every day with two 5D and two 5dmkII and I'm convinced they have both incredible value for money. Let's say from the beginning that the k-5 didn't change this opinion about Canon flagships. So, what the k-5 changed in my idea of the DSLR market?
Certainly the k-5 changed my consideration about the APS sensor format. I'm still unhappy Pentax doesen't have a full frame sensor, but since I tried the k-5 I think in some case we can live without: If the major advantage of FF sensors over APS is the sensitivity, we can safely say that the gap has almost been closed. Low light pictures from k-5 are clean enough to deal with a professional use. Not clean as the 5DmkII but comparable with the 5DmkI, which is already a big win!
High Iso performance:
5DkmII > [5D, k-5 on pair]
Yes, mkII files are cleaner in high ISO, what do you expected? And they are generally more detailed too but that is mathematics: more megapixel+excellent lenses = more detailed results. I forgot to say my lens is the 17-70 f/4 from Pentax. I compared it with the Canon 24-105 f/4 which has in FF the same angle and the same aperture. The Canon wins, no doubts, specially in the telephoto range. Unfortunately I don't have any recent prime to test with the k-5, but when I will win the 40mm of the giveaway I'll be able to test it against some Canon prime. :cool:
Resolution with the everyday use lens:
5DMKII+24-105 > 5D+24-105 > K-5+17-70
Yes, a better lens does a better job than 4 more mpx (16 for the k-5, 12 for the 5D). Now the good news: Low ISO noise: here the k-5 wins over the Canons being able to shoot at very clean 80 ISO vs 160 ISO which is the cleanest (not the lowest) ISO setting on Canon. Normally you will not find visible noise at 160 ISO on a Canon but think about that: where do you use low ISO? In bright daylight of course, and what usually happens in bright daylight? Two things can happen: you loose the shadows or you loose the highlights.
Shooting RAW you have a third option: expose for the highlights and recover a certain amount of shadows in post. You can do it very well on a k-5, fairly well on a 5D and... you pratically can't on a 5DmkII. Yes, you've read it well: you cant! If you try you will obtain a lot of ugly banding noise and no details on shadows. K-5 shadows comes up very clean and detailed, to the point that I prefer to underxpose a bit to have more highlights headroom. Moreover, if you're a strobist or working in studio you will find Pentax 80 ISO much cleaner in large prints than Canon's 160 ISO.
Low ISO performance
K-5 > 5D > 5D mkII
Sadly the bride have a white dress and the groom a black one, so with my mkII I have to choose which dress to sacrifice, specially in daylight where the contrasts are stronger. I purchased the k-5 for this very reason: the dream of having details in both dresses. So far I can say it works: I do have details in both dresses, even if I have to work more in post, and I have also better skin tones without ugly highlight holes in cheeks reflections. I can shoot streets at midday and people in strong backlight! I can manipulate the RAW as never before!
Dynamic range:
No need for my opinion here, the web is full of great reviews but its interesting to note how the 5D works better than the mkII in this regard. You can push 5D shadows obtaining a cartain amount of random noise, but not the ugly regular banding noise of the mkII. So 5D is much more usable.
k-5 > 5D > 5DMKII
Yes, I love my k-5 it but there are things I cant ignore:
No FF on the lineup: This means I will always need a Canon (or Nikon, or Sony) body with lenses to achieve the best quality in the more frequent shooting conditions (low light, for me), and that means I can't spend a lot for Pentax lenses.
Standard Zoom Lens quality : I've read a lot of reviews before buying the 17-70. On paper its the best choice in terms of versatility-resolution but it does not reach the levels of canon L series (maybe its just my copy but I don't think so). I know Pentax is strong with primes but come on! I can't always work with primes! I need some big, sharp as hell and fast Zoom to impress the bridesmaid and the groomsmen!
Handling: I've big hands! I never needed optional grips with canon but i may need it with the k-5. Bad thing! I have always considered exhibitionists the photographers who use the vertical grip and don't want to become one! :p
Value for money:
5D > k-5 > 5DMKII
She is still my winning horse: she has no weaknesses, she's cheap on the used market, you can always easily resell her and you can put on her a lot of amazing lenses.
The k-5 represents for me the way to go, the right evolution for the dslr technology but the lack of FF makes me doubtful in spending money in lenses and accessories.
Thank you for your patience, looking forward to read your opinion!

Hello everyone!
I'm from italy and I'm a recent owner of a k-5 camera.
Since I come from the Canon world (5d and 5d mkII) during my work I'm comparing the 3 cameras, and here I'm looking forward for useful pentax tricks. :cool:
