Lets face it, Canon COULD have done better with the 5D3. Ive been playing with mine for more than a week now, and I am seeing maybe .5 to 1 stop improvement in the sensor over the 5D2. Don't get me wrong, the 5D3 is a great camera. I would agree with some others though, that Nikon has produced a more revolutionary upgrade this time around. As a professional wedding photographer, I don't need more than 22MP. And all I ever wanted that my 5D2 did not have, was better AF, better high ISO performance, a dual card slot, and better video features. The 5D3 has all of that and more. So I am not complaining. I do however, expect Canon to step it up in the next round and produce something that really WOW's us.
