I agree with most of your review, and after using the camera more I am coming to appreciate the AF more, the images I'm getting appear sharper, but I think that's because the AF is more accurate

As far as high ISO though, I really don't see much of a difference until ISO 1600, and then I have a REALLY hard time saying why I like the 5DIII images better, but me and my wife both pick the 5DIII images as "better" when side by side with the 5DII images when they are next to each other. Maybe it's the better color at higher ISO, maybe it's more DR, I'm not sure!

I'm still a bit dissapointed that Canon did some verbal trickery with their marketing about "2 stops ISO improvement" and meaning "2 stop ISO improvement with in-camera JPEG conversions because of the better processor".

I'm happy you like the camera, I'm warming up to it! I still don't think I'll upgrade our other 5DII just because of the much higher cost, and will instead get a 35L that both myself and my wife are pining over!
