K-01 Bug/Improvement List and Lousy Image Engine

See what this careful K-01 user found and reported:-

http://forums.dpreview.com/forums/read.asp?forum=1036&message=41429633

Most of his findings are confirmed or agreed by yet another K-01 user in reply:-

Amongst all the above, I think the lack of focus peaking under video recording/movie mode is a real issue and would cause much inconvenience when using MF for video recording. This should be a hardware limitation I believe, e.g., not enough processing power or lack of additional hardware resource(s) for simultaneous processing and etc. Btw, my old NEX was capable to support this on day one.

Besides, the image engine of the K-01 is found to be lousy and inferior, at least when it is compared to the OM-D E-M5:-

So, here we go..

Well, the K-01 is completely knocked out! :-(

I'm wondering how selective your publications are, compare k5 and k-01 at dpreview and see what is the difference.
About the bugs even top pro cameras have them even if you pay $3k or more your not bug free, see what happened with d800 ,D4 that's pretty big Nikon fail ;-)

What about this sample from dpreview http://imgur.com/LqCks
Imho dpreview samples have some flaws make your own test and come to your own conclusion.

No problem. DPR is not the only website whom did such comparison tests. IR is yet another one but unfortunately the IR comparometer also shows that K-01's IQ is inferior to many, including the K-5. So, it's your take now, to show us how the K-01 exceeds others in IQ and we'd be glad to see other test results, especially when they are different, if and only if there is any!

Do you realize those images are focused differently? Of course you don't; you're just happy to find 2 patches on which a Pentax camera is apparently worse.
Btw, the Olympus OM-G's output (I know its real name, but allow me to use one more suited to the marketing hype Oly is known for) is way too overprocessed, I hate it. However, since I'm not the mindless monkey DPReview thinks we all are, I could probably adjust it to a satisfactory level.

You should just give your a poor blogger that does not understand the the rules of design you win hands down for the worst design blog. This is bad because you blogging that talk about a visual medium.

There no excuse for bad design wait a minute he is a engineer that the excuse. I love the work engineers do but design is not their strong point. Buy the way what does pentax have to do to make you happy.

Hi guys,

Don't you think most of those issues can be fixed with a new firmware update?

I have a K-01 and I'm pretty pleased. Autofocus misses sometimes though.

I don't think so. Maybe you can try different settings to see if the pictures come out to be "sharper", say for example.

Regarding the comparison to OM-D E5:

Your examples are highly flawed. If you go back to the original study, it is highly obvious that the two cameras were focused on a different focal plane. The K-01 was focused farther back, so you will find areas where that camera is clearly sharper than the Olympus... I guess, I can't attach an image to my comment - so just go back to the study and look at the playing card (queen) and you will find that my statement is correct!

Conclusion: With that kind of a study, it is easy to give "an opinion" one way or the other. This is OK, if (IF!) you make the viewer aware of the drawbacks and emphasize that this is your opinion. Don't try to suggest that you have hard data!

DxOMark use scientific methods unlike the rig methods you have just propagated. All i can say is shame on you.
