Canon Wireless Remote Control RC-6

I've been using this remote for self-portraits with my T5i and it works perfectly from across the room. The button response is instant, no lag at all.

The range on this little remote is surprisingly solid—I can trigger the shutter from across a large living room without any lag at all. It's made my self-portraits with my T6i so much easier to set up.

Finally got tired of the shutter delay on the self-timer, and this little remote fires the camera instantly from across the room. It works perfectly with my 60D and is so tiny I keep it on my keychain.
