Being the happy owner of a brand new D810 I do have a question; am I the only one who have something irregular going on with the monitor on the back?
Sometimes, and I can't reproduce it, it doesn't show the photo preview as usual. I have it set for 10 sec., and it simply takes a while (2-3 seconds) to show, if at all. Usually it is super fast, but once and a while it either takes a few seconds, or it doesn't even show. When it doesn't even show, I press "Menu" and that doesn't show either. I then wait a few seconds, and bingo we are back in business, and all is fine.
The first time it happened, I disconnected the grip as well as the internal battery, and put it all together again, but as I said, it is quite irregular.
