The ProMaster Multi-Function RF Timer Remote doesn't just trip your shutter wirelessly, it's also equipped to handle a long list of timer functions: self-timer, interval timer, long exposure timer, as well as controlling the number of continuous shutter releases. It works with a vast array of dierent cameras. Just swap out the camera release cable for the correct camera. The transmitter works at distances up to 300'/100m on any one of 16 channels over a reliable 2.4GHz frequency. Unlike a wireless IR remote, this RF version of our timer remote does not require a line of sight to your camera.
