Nikon shutter type options explained - which do you choose when?

A conventional camera shutter works in an entirely mechanical way. The shutter is fully closed before taking a shot. At the start of an exposure, the ‘first curtain’ opens, crossing the image sensor in the process. At the end of the exposure, the second curtain slides across in front of the sensor.

But at very fast shutter speeds, the second curtain starts to close before the first curtain has fully opened. That can cause a dark band in images when using a flashgun. The solution is to use ‘Auto FP’ (Auto Focal Plane) or High-Speed Sync’flash, which fires a short burst of flashes rather than a single flash.

Almost all Z-system cameras default to an ‘Auto’ shutter mode. This uses a conventional mechanical shutter most of the time, automatically switching to an ‘electronic first curtain shutter’ when it would be beneficial. As its name suggests, this uses electronics to initiate the exposure, but a mechanical second curtain to end the exposure. As well as letting the camera choose which type of shutter to use, you can select either option for yourself in the Custom Setting menu. In the Photo Shooting menu, you’ll also find a ‘Silent photography’ option. This enables a fully electronic shutter, making the mechanical shutter redundant.
