The Canon RC-1 Wireless Remote Control is a miniature infrared transmitter, handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure. It operates at ranges up to 16.4 ft./5m, and may be set for either instant shutter release or 2-sec. delay. It may also be used to activate mirror lock and bulb shutter function. When used with the EOS 5D Mark II, it can be used to start and stop recording videos, in addition to its normal still picture function.
