7D vs. 50D Shootout - all ISO's - JPEG, ACR, DPP Black Frames

Alex, can we iso compare 5D2 and 7D - we already have 5D2 baseline here - just set the DPP the way i did. All shots at 1/100

Thanks



It would be interesting to compare to a 5D2 ... since I don\'t have one, can you loan me yours?!? ;-)

Seriously, any chance you (or someone else) can shoot the same 16 images I did (using the exact same settings) and I\'ll post-process and add to my site so you can do side-by-side comparisons?

I have Photoshop actions so I can work through in a repeatable fashion and fairly efficiently so we have a true apples-to-apples comparison.


So what I need is put any lens on (I used 17-55 EF-S) and set to Manual, F/16, 1/1000s, ISO 100.
Set to max quality RAW+JPEG, and turn Noise Reduction OFF - everything else default.
In a dark room with the lens cap on, shoot at ISO 100, 200, 400, 800, 1600, 3200, 6400, and 12800.
Turn Noise Reduction to MAX and reshoot those same eight frames.

Create a zip file of all of that (will be about 500 MBytes!) and use some sort of decent big file transfer service (Conrad sent me one RAW file using transferbigfiles which worked well - RapidShare SUCKS!)


This would be an interesting comparison!

P.S. Yohan: Nice spot on the vertical line on the 7D - I didn\'t notice that earlier - note sure what\'s up with that, but not easily seen on other images.
