Nikon D500 - Manual (Page 73)

73 Menu Guide
When AF-C is selected for viewfinder photography, this option
controls whether photographs can be taken whenever the
shutter-release button is pressed (release priority) or only when
the camera is in focus (focus priority).
Regardless of the option selected, focus will not lock when AF-C is
selected for autofocus mode. The camera will continue to adjust
focus until the shutter is released.

Option Description
G
Release
Photos can be taken whenever the shutter-release
button is pressed.
B
Focus + release
Photos can be taken even when the camera is not
in focus. If the subject is dark or low contrast and
the camera is in continuous mode, priority will be
given to focus for the first shot in each series and
to frame rate for the remaining shots, ensuring a
high frame rate if the distance to the subject does
not change during shooting.
E
Release + focus
Photos can be taken even when the camera is not
in focus. In continuous mode, frame rate slows for
improved focus if the subject is dark or low
contrast.
F
Focus
Photos can only be taken when the in-focus
indicator (
I) is displayed.
