Hahnel’s HWC 433 is a wireless remote kit that allows you to fire your Canon camera's shutter release from up to 30 metres away.
The kit comes with a remote transmitter and a receiver that connects to the camera. Two connectors are also included and these allow you to use the remote with a range of Canon DSLRs and compact digital cameras.
Press the button on the transmitter down slightly and your camera will focus, press the button down fully and it fires the shutter release for you!
