The Nikon ML-3 Compact Modulite Remote enables remote control for two separate channels via an infrared LED beam, providing automatic camera operation from a distance of up to about 26-feet (8 m). Auto triggering, delayed shutter release, single and continuous shooting are possible. It can also fire the camera remotely when a subject moves between the transmitter and receiver, for surveillance or wildlife photography.


The ML-3 is designed so the transmission button operates the same way as the shutter release button of the camera. Lightly pressing on the transmission button turns on the camera's exposure meter and starts autofocus detection.


To connect the ML-3, the receiver is inserted and locked into a camera's or Speedlight bracket's accessory or hot shoe and is then connected to the remote terminal on the camera with its remote cord. The camera is fired when the transmitter is pointed in the direction of the receiver's sensor and the transmit button is pushed. Recommended camera settings are: C or M focus modes, Programmed Auto (P/Ps), Aperture-Priority Auto or Shutter-Priority Auto, L or H film advance modes.
