The Canon RS-60 E3 Remote replicates the functions of the shutter release button and thus allows prefocus, focus lock and actual shutter release. It also features a shutter lock, allowing you to use extreme long exposures in bulb mode. The remote switch is compatible with any Canon EOS camera body that uses the mini-jack remote socket. With the RS-60 E3 Remote you can take pictures without touching your camera, ideal for when you want to avoid causing vibrations
