I am sure the 12800 iso and 25600 iso samples beat my K-7. I hope B&H gets my yellow K-01 body soon.

I think he doesn't like anyone who says any good words about Pentax stuff, especially the current Pentax products

We could fill a forum discussing people like Rice High
Then again... isn't that exactly what he wants?

It is a strange approach to take imo. but it obviously works because the guy has been around doing what he does for longer than most sites I know of.

Rice High is a real weiner, he posts Canon 5D MKIII samples on his Pentax Blog. BTW I think the Nikon D800 is going to kill Canon 5D MKIII sales with more detail in stills and better 1080p video features at a $500 less cost.

The amount of NR used by mfr engr can vary from one model to the next. Sorry to say it, but i think NR needs to be turned off on both cameras before one can come to a meaningful conclusion.

Look at the RAW files. In-camera NR has no affect on them.

Just finished uploading second test results, it's in the first post of this thread:

Since last night's test was a bit rush. Tonight I did a similar side by side test again between K-5 and K-01. Just for a reference, I also added Panasonic G3 in the test so I'd see how a smaller sensor compares w/ the bigger APSC sensors.

Here is the testing setup:

1. indoor w/ ceiling light (a bit brighter than last night one so to help w/ manual focus), also around mid night to avoid light changes
2. tripod: Gitzo 1540, ballhead: Markins Q3
3. K-5 and K-01 had FA31 mounted, G3 had Panasonic Leica 25/1.4 on
4. both high ISO noise reduction and long shutter speed noise reduction were disabled on all cameras
5. all lens adjustments were disabled if there is an option there
6. D-range highlight/shadow correction were disabled
7. manual exposure mode was used on K-5 and K-01 so to keep the same exposure settings on both camera , Av mode was used on G3 (the camera has pretty good auto exposure in Av mode, and it's not a priority in this test, so I just let the camera do the job)
8. all cameras set to auto white balance (tried manual white balance, can't get any better colors than auto ones )
9. manual focus was used on K-01 and K-5, w/ focus peaking enabled on K-01 (enlarge 6x w/ FP), used live view w/ 10x zoom to help manual focusing on K-5. A few testing shots were taken and reviewed (enlarged to 16x) on back LCD screen to verify the focusing just to make sure I've done the best on focusing. Auto focus was used on G3 (again, this camera w/ PL25/1.4 just never fails on AF)
10. K-01 and K-5 were set to wireless trigger w/ 3 second timer, G3 was set to 2sec self-timer
11. aperture was set to F5.6 on K-01 and K-5 so to get more DOF and reduce the impact of focusing error. G3 aperture was set to F4 (which is probably the sharpest aperture for PL25/1.4 lens)
12. tested both in JPG and RAW (G3 only tested in RAW), ISO setting:100 (K-5 and K-01 only), 200, 400, 800, 1600, 3200, 6400, 12800 (K-01 and K-5) and 25600 (K-01 and K-5)


From what I can see on my screen, the test results are pretty inline w/ what I got yesterday: photos from K-5 are a tad bit (1/3 to 1/2 stops) brighter than those from K-01 at the same setting, and again, K-01 photos seem a bit sharper (I've tried my best to focus properly on both cameras, and the AF results from K-5 under such light condition just can't compare w/ what I got w/ manual focusing in live view). High ISO noise evel is about the same, except at ISO25600 which K-01 isn't as good as K-5. I guess it's because ISO25600 is the extended ISO on K-01 while K5 ISO can be extended to ISO51200.

High ISO from G3 obvious loses to K-5 and K-01 in details and resolution, especially at ISO3200 and 6400. But it's pretty close or even slightly better at lower ISO (at least to my eyes). I guess the smaller 2x crop sensor isn't too bad at all.

Enough talk. Here I've uploaded all the original files on 4shared. I think you need to register an account (free of course) to download them. It's a free account, I don't know if there is any bandwidth limit. Sorry I can't find a better way to share such big files. File names are very obvious, you won't make mistake w/ the cameras and ISO settings on each photo:

4shared - K5vsK01 - shared folder - free file sharing and storage

There is a video file in there too, probably too short and too badly taken to show how capable this new camera is as a video camera.

Hope these can be some help to some friends who are interested in this new camera.

[MrMotivations]

Frank,
Thanks for sharing your files. I have particular interest in seeing how the video represented.

[monochrome]

Frank: You are a gem. I've started my contribution - although I won't get the camera for a couple weeks.

[JerryLime]

Good sharing, Frank.
I do not think K-01 is sharper than K-5.
I guess if K-5 uses Liveview, that will do better on sharpness.
At the same time, there is different color rendering between both bodies.

I'm not 100% certain but it looks as though the K-5 ISO100 DNG might be damaged.
I downloaded several copies(3) with the same results.

Other files seem to work btw.

Why don't we all wait and see what Pentax/Ricoh brings at the top of the next product cycle before we judge them so harshly.

I didn't think my simple statement of fact was "judging them harshly". And I am not the sort of person who needs the next greatest thing, so I would hardly be criticising Pentax for sticking with an established and lauded sensor.

(Now if they'd dumbed down the IQ for this camera, that I would criticise.)

Hope you'd have your K-01 in hands soon

Good sharing, Frank.

Yeah, I tried to focus as better as I could on K-5, and the results looked really sharp on K-5's back screen (same goes to K-01). But when I view them on my 24" Dell screen, the difference is pretty obvious. And factor in the F5.6 aperture I used (to get enough DOF), I really don't know if I can make K5 results any sharper.

Hmm, sorry about that. I just re-uploaded the file. Please try again and let me know if this time it's okay.

I can't download any samples now

Just want to say "Thank you" to frank!
Great work

Jusk want to say Thank for efforts and help to Frank
