Recently, Nikon has published FW updates for the D500, D7500, D5600. Same as the D850, the two main problems addressed are:
- A fix for the Snapbridge app
- (more important) a fix for improving the autofocus in marginal areas of the focussing sensor grid
I use compatible batteries and a compatible grip on the D500, with original EN-EL15x batteries and compatible EN-EL18 batteries. Works perfectly after the update. The shutter count in the
battery info menu is updated correctly. I assume they haven't slipped any anti-compatible-battery "bugs" even in the D850.
