Switching modes on the D800 is really, really bad.

Unless you have hands the size of Andre the Giant, there is NO WAY you can switch between P, S, A, M without letting go of your grip on the camera to simultaneously press the mode button and move the thumb dial on the back of the camera.

And it’s not like removing your hand from the grip makes it easy. It’s still a rather awkward stretch, especially for anyone with small or even average sized hands.

This is an incredible design flaw on the D800. It absolutely amazes me that Nikon could let something like this slip by.
