The Canon RC-6 Wireless Remote Control is a simple, compact, infrared remote control that makes it possible to fire a camera wirelessly from as far as 16' / 4.8m. The RC-6 will operate in either 2-second delay mode or will instantly take a shot. The RC-6 is only 2.5" / 63.5mm tall and can fit easily into your pocket or on a keychain.
Works perfectly with my Canon T6i — both instant shutter and 2-second delay function flawlessly. It’s tiny enough to keep on my keychain, and the included battery was a nice bonus. Great little remote for the price.
