The Nikon MC-DC2 Remote Cord is a wired release cable which adds greater convenience and ease of use in a wide variety of shooting situations, including long exposures and close-ups. By using a remote cable you can reduce camera shake, which results in sharper images. The remote also features a lock, which keeps the camera shutter in Long Time Exposure (Bulb) mode. The cord is 3.3' (1 m) long.
