The Intervalometer Controller for Canon Rebel, Powershot, 60D, 70D is a remote system that connects to certain Canon cameras via a sub mini connection. You can autofocus with it, lock it down when shooting in Bulb mode, or set a variety of intervals for time-lapse photography. See our Notes tab for a full list of compatible cameras.
Please note that you can shoot 1-99 shutter counts or infinity shutter counts. This is important because if you want to shoot for 2-3 hours but can't return to your setup in that time, your only choices are to shoot only up to 99 shots or let the camera shoot on infinity mode until you return or the battery dies. Plan accordingly.
