After reading the beta-tested review of the 7D I came away thinking it will be a slightly improved 50D in the IQ department, but still not going to replace a basic 5D IQ or more realistic DOF. The high ISO claims are just that. Even the best crop DSLRs get noisy after 1600. I have a feeling that running 8 FPS constantly on a non-professional camera will take it's toll on the shutter designed for less actuations than a 1D series if sports is your speciality. The weather sealing is nice... finally, and the AF speed seems to be a winner as does the improved screens. The flash transmitter is also nice, although it's buried in the menu. I didn't see mention of ratio control like on the ST-E2 unless it is also buried under other subsets. Overall, it should sell very well depending on the economy of course. I'm keeping my FF camera, though.
