I like everything except the 22MP. I guess they're aiming at their video market with this camera.
This pixel density is way lower than the 7D and the 1D X is even lower density (aimed at sports photographers). I wish that they'd aim a FF camera at wildlife photogs others that want maximum detail, without sacrificing noise too much.
I may have to buy a 1D MkIV before they discontinue it.
If I didn't have so much already invested in Canon lenses, I'd be seriously considering the D800.
