So while I didn't preorder, I did go to a camera store today, and lo and behold, they had a 7D. Impulse buy!
Anyway, for those that are interested (probably everyone), my semi-scientific iso test.
These are images viewed at 100% in iPhoto, and then screen grabbed. These are resized screen grabs, but click through to my flickr to see the 100% screen grab (the images are 1.8 MB each, so I'm not posting them here).
Hand held, Manual exposure, EF-S 17-55, f/2.8, AWB, Jpeg:
Again, RESIZED IMAGES -> CLICK TO 100%! Because these are resized by flickR, this can sharpen and intensify the noise.
