Comparative ISO Tests

All shots were taken with the assistance of a tripod. Shot in AV mode with Canon EF 24-70 f2.8 lens.

RAW images were converted using Raw Shooter Premium with no adjustments. The resulting TIFF were then resized. No sharpening has been applied. I have shown each shot in it's entirety and then a 100% crop to further illustrate the noise has been inserted.

I am comparing the Canon 5D, 1DMKII and the 20D

Very surprising results... I would have thought the 5D would have out performed the 20D... but it doesn't look to tbe the case. Very interesting.
