This unit functions as a simple cable release, as well as a self timer (releasing the shutter after a delay you choose), an intervalometer (tripping the camera shutter at set intervals of time), a long exposure controller when the camera's "B" manual shutter setting is used, and a shutter trip counter for a set number of frames. It permits combinations of these functions, also. With a camera mounted on a tripod, this (wired) remote controller will permit a photographer to do far more than simply reduce vibrations for a photograph. Time lapse photography and city lights, fireworks, and night sky photography can be added to your repertoire. You do have to be mindful of some limitations. There is a slight delay in tripping the shutter after the button is pushed. It may not take the desired number of frames if the interval between frames is too short. Do an experiment first to find out how short the interval can be. Use only brand new AAA batteries - if they are even slightly weak, the remote controller won't work. Take the batteries out of the unit if you only use it infrequently. The batteries may weaken or wear out between uses since the internal timer keeps running as long as there is power available to it. This is an inexpensive and functional back-up to the many-featured Canon-branded cable release. It fits Canon's "prosumer" cameras and a few others; check the Canon website to confirm the connector needed for your camera matches this connector.
