How reliable is the studio test on dpreview? 7D sharpest of them all.

Guys, if I compare the raw files of 5dIII, 5dII, D800 and 7D at any ISO and "zoom in" on the queen of hearts, the 7D is the best camera around. ;D.

OK, must be something like focal point I guess, but in a studio test the focal point could be (should be) the same if you take shots to compare hardware.

How come the black and red of the 5dII and the 7D on the Kodak card are similar and completely different from the black and red of the 5dIII and D800 (which are strangely enough similar too).

Sorry for being so ignorant, but can this be explained or is DPR not to be taken serious?

There are a lot of things that can cause minor differences, a crop camera only uses the center portion of a lens, and might look sharper on some lenses. It is going to be a marginal difference. Also, remember that the 7D has a much higher pixel density, so if everything is perfect, it might appear sharper because of that. The image is likely larger for the 7D, and that makes some people think its sharper too.

Looking at the 100% test images and judging sharpness is more of a personal preferance, and different people look at different things.

LOL, check out the queen with the 50D! Blows everything else away. Seriously though, it's just a focus plane issue is all. Doesn't mean DPR can't be taken seriously, just means you have to understand what you're looking at. That said, I find it useful for comparing noise qualities at various ISO for different cameras, but that's about it.

I don't believe the 7d will be better but this i do believe, it is a friggen accurate focus system on the 7d! I own a sports photog business and as such hire other shooters and since a few of them upgraded to the 7d they have far fewer out of focus images. I can attest to its excellence in focussing. I find the keeper rate better than my 1Dmark 3.

It's simply a focal plane issue. The queen of hearts should not be in focus; the focus is set slightly too far back on the 7D images.

The focal plane is very sensitive in these shots, sometimes a matter of moving the camera forward or back a single millimeter can have a significant effect on how two cameras compare.
