The Canon RC-6 Wireless Remote is a must-have tiny infrared wireless remote controller for compatible Canon EOS DSLRs 
 
 
Measuring only .25" x 1.25 x 2.5" (6.5 x 32 x 63.5mm), the Canon RC-6 Wireless Remote easily fits in even a small pocket.
 
Unlike the Canon RC-5 Wireless Remote, the RC-6 will operate in either 2-second delay mode or will instantly take a shot (like the Canon RC-1 Wireless Remote).
 
Point the Canon RC-6 Wireless Remote toward the front of the camera (line of sight only) within 16' (5m) and take the shot when you are ready. Or use it to start a video.
 
Using a wireless remote release eliminates camera motion related to pressing the shutter release - and allows you to be a subject in your photo. Being able to stay near your subject to assist in composition (or ease stress) is another benefit.
 
The Canon RC-6 Wireless Remote is powered by 2 CR2032 Lithium button batteries rated for about 6,000 transmissions. The Canon RC-6 Wireless Remote is a very useful device - and having no cord is great. You can even put it on your key ring.
