The Off Brand ML-L3 Wireless Remote Control (Infrared) for Nikon is for use with the following Nikon cameras: D40, D40X, D50, D60, D70, D70S, D80, D90, D600, D3000, D5000, D3200, D5100, D7000, Coolpix P6000, P7000, P7100, N65, N75, Coolpix 8400, 8800, Pronea S, Nuvis S & Lite Touch Zoom Cameras, Nikon 1 J1, Nikon 1 J2 and Nikon 1 V1. It acts as a wireless shutter release capable of instantly triggering the shutter without disturbing the camera, up to a distance of approximately 16' (4.87 m) in front of the camera. The remote can work from behind the camera as well, however its range is not as long. It is recommended for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure, and it is powered by a CR-2025 3v battery (included). The ML-L3 supports the bulb exposure camera setting making it a worthwhile accessory for shooting long time exposures for low-light photography or unusual daylight effects.
