What is the live view performance like on the Nikon D800.
In particular how good is the AF ond face detection, especially in the corners for those times when you want the eyes out side of the focus area of the main viewfinder.
Also I have read that the magnified live view for manual focusing is a bit on the slow side as far as refresh rate goes.
Also is it possible to shoot with crop marks... say 4x5 (magazine aspect ratio), but have the frame offset from the center in the bottom of a vertical so as to keep the models face in the viewfinder focusing area as well as nearer to the sweet spot of the lens. Basically crop marks cropping off the top off a vertical frame.
