Canon EOS 450D/500D/550D/5D2/7D/60D/5D/MARK II

Point the Yongnuo 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 Yongnuo RC-6 Wireless Remote Runs on one CR-1220 lithium button battery (included). The Yonguo RC-6 Wireless Remote is a very useful device - and having no cord is great. You can even put it on your key ring.
