For some reason my speed lights have stopped functioning on my Nikon D850; I use two SB900's an SB700 and an SB600. All have worked on this camera body in the past, and now I can't get any of them to function. Sounds like a hot shoe problem, but other accessories (studio lighting controlers/triggers) do function properly. So there seems to be some issue that is specifically flash related.
Any suggestions would be greatly appreciated!
