Fires your SLR from up to 65 feet away with radio frequency signals for reliable remote control, even when you're not within direct line-of-sight of your camera. This transmitter and receiver set is excellent for portrait, wedding, wildlife, surveillance and other types of photography that require dependable triggering of remotely positioned cameras. The receiver has a shoe for mounting on the camera or flash bracket and features a 4 ft. coiled cord that plugs into the camera's remote control terminal. It fires the camera when signaled by the transmitter, and also has a shutter button to trigger the camera, thus serving a second function as a cable release for vibration-free firing of the shutter. Compact transmitter slips into your pocket like a key fob and has a 2-position activating button. Pressing the button to the first stage activates your camera's autofocus and metering systems; pressing it all the way fires the camera. Four switches on each unit allow you to select any of 16 channels for interference-free use. Kit includes CR2 3V lithium battery for receiver and 23A 12V battery for transmitter. 100994 is for the Nikon D70s and D80. CLEARANCE, while supplies last. Original price $119.99, buy now and save!
