The Remote Release for Nikon D70 allows the Nikon D70 & D80 DSLR cameras' shutter to be released from a distance helping to reduce camera shake and allow the photographer to be at a distance from the camera. It features a three position switch. The first position focuses the lens and sets the meter. The second position releases the shutter. The last position locks the release for long timed exposures and continuous video operation. All electronic, just plug-in and use. The cord is 35" long.
