Sorry to hear the final curtain went down (pardon the pun) on your D800. Looks like you resisted the pull to go Sony. How's the D810 working out? Canon just d/c'd support for my 1D MkIV so I'm doubling down on trying to get a back up (don't need FF for everything). Did go through the mental process of switching to Sony (and Fuji) though.
The 800 was mine, the 810 belongs to the paper. I picked it up when the 800 died to go along with the D4.
I will have to buy another camera for myself. I still have not ruled out fixing the 800. Finances being what they are and the real threat that I may be out of work in a few weeks are keeping me reeled in.
If and when I start over with camera buying I may just jump into the mirrorless world.
