I just couldn't hold out any longer. I have ordered a new Nikon D850 plus battery grip from those great people at Wex Photographic. They are Nikon Pro dealers so as I am part of the Nikon Professional Service (NPS), I get priority service which means it should be in my hot sticky hands before too long.
I doubt I'll have it before the conference I am covering next week (but you never know), but I've a rather special event at the end of the month it would be perfect for. Come on Nikon!
