Nikon has issued firmware updates for its D500 and D3400 DSLR cameras.

Firmware version C:1.10 for the D500 adds support for the iOS version of SnapBridge and introduces some changes to the help text. It also fixes the following issues:
– Images would not display correctly if playback zoom was used during image review.
– The focus point display would not light if the shutter-release button was pressed halfway after the standby timer had expired.
– The camera would stop responding if a command dial was used in the  CUSTOM SETTING MENU  >  f Controls  >  f1 Custom control assignment  >  Movie record button  +    menu.
– If an option other than  Off  was selected for  Active D-Lighting  in the  PHOTO SHOOTING MENU, pictures taken with an optional flash unit in auto aperture (AA), non-TTL auto (A), or distance-priority manual (GN) flash mode would be underexposed.
