The Wireless shutter release is handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure. It employs a superior anti-interference functionality and allows a choice of 16 different RF channels. This is particularly useful if several photographers are working in the same vicinity as you need only choose a specific channel for each photographer to prevent overlapping signals.

Another use would be the ability to control multiple cameras with a single remote by assigning each camera their own receiver channel and switching the channels on transmitter. Range up to 100m (320ft.) without obstacles - Retractable antenna for Long range shots! Designed for groups, macros, Time Lapse Mode, Long exposures / Shutter Mode, Continuous shooting mode, etc.

Compatible with 20/30D/40D/50D 5D Series and 1D Series
