It's funny, in a sad way, I keep going back and forth about these. I've had my D850 since March 2nd and have yet to even open the box. It has sat in my camera safe (gun safe haha) untouched for 5 months plus.
The more I think about it, the more I am leaning to the D500, but I'm still on the fence! Ugh. Need to decide in the next month.
