The Opteka RFT-40 adds flexibility and
versatility to your shooting style. Shooting wirelessly allows you to do things
other than standing behind the camera i.e. you can interact with a model,
experiment with different shooting perspectives or duck out of sight of elusive
wildlife - all this and more without missing a moment.
This item includes the receiver only. It will not operate without the main
trigger unit. Each trigger supports up to four receivers.
