The Nikon MC-DC3 is a remote cord compatible with the Z50II and later models equipped with a headphone/remote cord connector (3.5mm jack). The cord is approximately 3.1 ft/ 1m in length. It is useful in minimizing the effects of camera shake when using a tripod to photograph starry skies and nighttime scenes, or with commercial (product) photography. It can also be used for remote photography to release the shutter at a distance from the camera. The shutter-release button can be locked in the fully pressed position for long exposures (bulb shooting) or held down for continuous shooting. It can also be held halfway down for shooting with less release time-lag.
