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.
