The Wireless Controller LC-5 is also equipped with three channel settings (A, B and C) to ensure that multiple remote Canon users do not inadvertently set off someone else's camera or in situations where a single photographer is remotely triggering more than one camera set-up. In that instance the photographer has the option of firing the separate cameras individually and at will or all at once by selecting the unit's "ALL" setting.
Among the expanded capabilities offered by the LC-5 that were unavailable on the predecessor models is the improved one-shot release mode (1SR) that permits the photographer to pre-focus the camera and then essentially lay in wait - virtually indefinitely -- for the subject to cross into range. By pressing the LC-5 transmitter trigger fully, the LC-5 remote receiver can now "wake" the camera from its energy saving "sleep mode" and capture at will the image that the photographer has patiently been waiting for. In other than 1SR mode, the photographer needs only to depress the remote transmitter's trigger button halfway to engage the camera's autofocus before shooting.
