After getting it today, I have run my D810 through the paces and noticed some unusual behavior with the multi selector (d-pad, directional pad, etc.). When reviewing zoomed-in images to check focus I have no problems scrolling quickly up, down, right or left, but diagonal scrolling is very hit or miss -- mostly the latter. Sometimes the multi selector will respond to a quick jab and track diagonally across the whole image with no problem; many times this does not do the trick. Full-force pressing almost never elicits a response from the camera when pushing diagonally. The most effective workaround (if you can call it this) is just to stab diagonally two or three times until the camera finally responds to the input. This is less than ideal and would certainly result in a sore thumb at the end of a shooting day!
Has anyone else had this issue, if even only intermittently?
