Expert Tip

Firing the shutter without having to worry about hunting or refocusing is a major benefit of using back-button focus. But if you find yourself unable to activate the shutter without placing the AF point over the point of focus, we’d recommend setting up your AF-C and AF-S priority selection so the shutter overrides focus. We set this up on our D850 by heading to the Custom Setting Menu>autofocus, and setting both AF-C and AF-S priority selection to Release.
