That's assuming the full frame lens performs as well as the APS-C lens at the corners, which would mean a lot more $s.downtime said:I'm a bit picky when it comes to pixel density. Especially when buying point and shoots. But from the impressive quality I've seen from the 7D I'm optimistic that we could see a fantastic image from a 48 MP sensor in a 36 x 24 mm format.
Canon's new EF lenses are so expensive, I'm already considering either a downgrade to the 7D or a switch to the Nikon D700. I'll wait until the end of Canon's lenses year (I expect nothing special, but I need time to save some cash anyway) and decide.
