Conclusions
Well, this is just a spec analysis, but on paper the EOS 7D is certainly a more fully featured camera than the EOS 50D. It's likely that for most users in most situations, the image quality will not be dramatically different from that of the 50D, but it does have some nice additional features such as video and built-in wireless flash control which simply aren't present in the 50D. I'd be very surprised indeed if the EOS 5D MkII didn't provide higher image quality from its full frame sensor, but than at $1000 more, it should!
If I was in the market for an APS-C crop sensor camera, the EOS 7D would be my current choice based on specifications and capabilities. As soon as I get a chance to test one, I'll be able to give an assessment of image quality and how well the updated exposure and AF systems work.
