I like the 1D MKII a lot and I still use mine for many commercial shoots, but the 7D has a lot of nice features. I think the screen size, improved controls and better menus makes the 7D a step up from the MKII. The great thing about the 1-series is the build quality and the weather sealing.
I would get the 7D for features, resolution, better high ISO performance, and better screen than the 1DIIN. It would also be nice for (non-wide field) astrophotography due to its high pixel density.
Awful tempting.
For the price I would get a 1DmkIII.

Thats all nice and dandy, but when you down rez the 7D to the same resultion as the 1D IIIthe 7D looks VIRTUALLY the same as the 1D III. Basically you get more resolution without more noise in your print.
Here are some samples

I also applied crominace noise reduction and sharpened them, so sharpness is about the same.

I believe the DXO mark results already take that into account. In other words, the number given is the ISO at which the amount of noise on the whole sensor reaches a given threshold.
I'm not saying they're right and you're wrong, but just clairifying what they are claiming.
Where did your images come from? How were they exposed?
The cropsare from Bryan's reviews, kinda suprisedyou didn't catch it though....[]
I'm not really sure how they get those scores, but DXO has a graph with the signal to noise ration. So I don't know what the ISO score is for....[^o)]
There might be more differances at a sub-pixel level, but just looking atit 100%they look pretty dang close too me....[Y]

If I understand correctly, it is the ISO at which noise reaches some threshold level. So the higher the score, the better.
Me, too. That's why I asked about how they were exposed. One should use manual exposure when doing such tests to assure each camera is getting the same amount of light (if you rely on the meter, one camera may leave the shutter open longer at the same iso, thus giving itself more light an an unfair advantage). I *thought* Bryan used manual exposure, but the 7D image says "EV + 1/3" which seems to indicate the meter was used, and furthermore, that the 7D was given 1/3 stop more light, enough to make up the difference reported by DXO.
Anyhow, I'm not sure I could tell such a small difference anyway.
