I think colours are actually better on the 60d at 100 and 1600 iso especially... notice how the k-5 loses the detail in the red cloth at 1600 iso but the 60d retains it.

Hrmm d7000 colours are nicer to my eye too, I think the Pentax is running too much saturation perhaps by default?

I see purple fringing in highlights on Pentax, none on Nikon...

Colours are over saturated to me on Pentax. Hard to say without the real objects in front of me which is more accurate but i get the impression nikon is.... and i get the impression canon is even more accurate.

At 6400 iso the K-5's noise is much better than the d7000's unless the uploaded jpg has some corruption but the K-5 has for some reason lost all detail in that red cloth swatch. 60d also loses detail in the red at 6400.

Actually the K-5's noise pattern at 6400 is very nice, no colour noise at all, where as d7000 has some and 60d has lots.

Million time better test than DPR's though, at least shit is in focus here.

Depending of the color , camera look very different Very interesting. K-% look good but I could say D7000 is Ok too except at black at high ISO

d7000 has hot pixel near the leaf on bottom right

Many thanks for the heads-up.

The K-5 test images must still be in progress - as the very useful Indoor Portrait, No Flash series isn't yet up as of the time of posting. However the (studio) still life series which are very useful are already there.

Look forward to the other test samples, as they are posted

Thanks

haha, you are comparing cameras JPG engines in these imaging recources tests

I always take pictures in RAW, there is no any problems with reds in high ISO like in JPG. I own K-5.

This test does seem odd. Strait jpg images? Comparing enthusiast/pro cameras, why would anyone want to know that? And also looking at the exifs, if they are correct, there are some strange things going on. For example K-5 at 70mm f/5.6 compared to D3x at 70mm f/8, in the "still-life" images.

For beginners grade cameras I can see the point, but I can hardly see anyone buy a D3x for it's jpg qualities.

I was with a Pro photo working for newspaper and he use 100% of the time JPEG and he have a D3X
PS I use RAW myself

I was a bit shocked too when I first saw the photos there. I had in mind that their review of the K7 showed horrible loss of detail on that red cloth. So I was curious to see what the K5 photos would look like. Then, in comparometer, I didn't trust my eyes as K5 was even worse compared to K7 at ISO 3200. Shocking! However, I got suspicious when the D7K images looked so much better. The same sensor? That difference? No way. So yes, downloaded the raw file, converted myself, had a look, and... lots of detail on the same red cloth. It's either the camera's color profile settings or a real flaw in the jpeg engine. Both completely irrelevant if you shoot raw and both probably solvable by either different settings or a firmware update.
