WOOOHOOO! DPReview seems to have fixed the comparison shots!

I just re-checked the DPReview jpeg comparison widget thingy, and it seems that they have re-uploaded shots for both the Nikon and the K-5!

And guess what! Surprise, surprise, the K-5 takes the cake at ALL ISO's!

Interestingly, the Canon 50D still seems to be suffering from some sort of focus issue, as it's quite soft. Perhaps this is to convince Canon users of the need for an upgrade?

Here's the (broken) link:

Wow the file size on the K-5 is ridiculous. At 6400 ISO Raw, the K-5 is 30.2 MB while the 7D is at 29 MB. Can anyone explain that? The D7000 at 6400 ISO is only 23.4 MB.

In that D3 comparison all I see is a lot more detail retention in the material. Same for the D7000.

They are all really close. It's a question of what noise processing outlook you prefer. I doubt any of them is significantly better.
Now if you look at the RAW versions, Pentax might actually be somewhat better.

K-5 jpegs don't come off well at all to my eyes in those crops, it looks like the NR is quite aggressive. RAW is probably a different story though.

The D3 looks stella, as it should be being FF and $$$$$.

In terms of noise in RAW the K-5 does actually fare quite well, and to me is likely the best of the bunch. (60D, D7000, K-5) Although the differences are minor, it does look as if more NR is happening on the K-5, so it tends so scale a little better.

I'm not so impressed with the K-7 vs K-5 @ ISO 100 RAW tests, where the K-7 looks to give noticeably sharper results than than the K-5.

Anybody else?

It seems if you compare the low ISOs on the different cameras, the K-5 blows them all away. Also, the color seems to pop more with the K-5.

Credit where credit is due to dpreview for re-doing the shots. It makes a visible difference, to the benefit of the K-5. Clearly the first round of shots were a bit rushed and imprecisely set up.

Imaging Resource have now released a series of K-5 test images too. Hopefully their testing workflow doesn't have similar issues, as a result of the rush to get some comparisons out:

Much better from DPR. In RAW at ISO 200 K5 (and D7000) utterly demolish the 60D (which is already showing a good deal of noise--check out the Bailey's bottle). By ISO 800, the K5 clearly starts pulling away from the D7000, showing itself less noisy. After ISO 1600 it gets harder to judge as the different approaches to NR show.

Edit: Another good place to look is the Martini bottle, just above as well as to the right of the brush. At ISO 100 for the others, ISO 80 for the K5, you can see an advantage to the K5. Even the D7000 shows just a touch of noise, unlike the K5.

thanks for the heads-up. I took a closer look at the samples on DPR. what I noticed is that the K-5's jpegs are sharper than the D7000 except at ISO 12,800 and 25,600 where the images are softer compared to the D7000. I would assume that this had to do with the Pentax auto-NR at High ISO. interestingly enough, the D7000's RAW are sharper than the K-5's which leaves me with the notion that the D7000's processed RAW results would produce a much more sharper and detailed final image.

however, having said that, the D7000's jpegs produce blotches or smearing at Higher ISOs which could affect the final cleanly post-processed image. the RAW samples also show a significantly high amount of chroma noise on the D7000 at High ISOs which could affect the final outcome of the processed RAW image, while the K-5 is impressive in eliminating such destructive noise substantially.

personally, I would say that both cameras are excellent in their respective way. the D7000 has better RAW from ISO 100-6400 (ISO 3200 still has excellent Noise Control, while 6400 can be cleaned nicely and produced great results after post-processing). the K-5 gives you that added flexibility of shooting at much higher ISOs under very demanding lowlight situations and still be able to retain a good amount of IQ and produce some nice/very good (at times impressive) results added with a half stop DR advantage on average.

for sure, both Pentax and Nikon owners would be very pleased.

D3 is good, in D7000 I do see more detail BUT, on the balck there are ugly blue blotches and umm I'd rather have less detail that blotches that are this apparent....
Also , I think while the D7000 appears to give more detail on the material on the left< I ma quite conofused by this, it seems more liek an oil painting texture and it seems alltogether different than the D3 texture, D60 comes closest to that and then K-5 but softer... It is like the D7000 made a picure of something with a completely different texture... Not that one who does not pixelpeep would notice....
