What would be the advantages of upgrading from the Canon 40D to the 7D?


Would the pictures be any sharper or better because of the 18 MB?


I notice on my 40D that when I shoot in rapid sequence that the exposure of all the pictures are not the same. They very approximately a half a stop. During processing the data shows the variance in the exposure although the pictures were taken within a few seconds of each other. Would the 7D correct this?


any opinions would be appreciated
