Sometimes the best way to execute the shot you want is to not touch the camera at all. The Shutterboss Timer Remote allows us to do just that. With a 3 pin connection for canons, the wired remote can be set for either a number of shots or unlimited shots with delays and intervals. This allows you to control taking the photo without touching the camera, and prevent the camera from shaking. The timer is highly suggested for those Time-Lapse recordings and night shooting.
