not bad, but it seems like its not entirely worth 2 grand. 19 AF points and more of a plastic body? -_- smaller form factor I guess isnt so bad, but if its looking like I rebel, then no thank you. pop up flash, I suppose is an added bonus, something you dont see in the 5D line. its been a savior here and there. But I think I will keep my eyes on the mrk3 for my next purchase.
