Not much, in this case, Akira. It is ease technologically, but more sensible to shake and knock from the side, less so from the front. But what is really nice, the new shutter unit. Very smart shocks absorptions finally included, so, the biggest Nikon's problem with stable shutter inconsistency of 1/90 - 1/180 is , finally, addressed. At least I believe it now, so painful was it for half of the century. Yeah, very smart shutter, almost equal to the one of D5. Let me be sure its DR is, at least, equal to the D810 one, and I will take a very close look at it. LZ
