Cactus Wireless Shutter Release for Canon EOS 50D 40D 7D 6D 1Ds

Out of stock

With the wireless shutter release, you can control the shutter of your camera from as far as 15 meters away.

The package comes with a handheld wireless transmitter and a wireless receiver to be plugged into the the shutter release port of the camera.

Different from the infrared remote control, the radio-triggered wireless shutter release can work as half-pressed button. In other words, you may let the camera auto-foucs before finally taking a shot. 

Another improvement over the infrared remote would be the support of the bulb mode. You can obtain an exposure for as long as you wish.

This wireless shutter release has strong anti-interference function and has 16 channels for you to choose. It is extremely useful if there are several photographers working nearby. Each photographer could choose their own channel to trigger off the shutter release of the camera they are going to use without triggering others’ because of overlapping signals.

This unit can be triggered continuously for 20,000 times. The energy-saving design allows you to use the unit for a year without having to change the battery inside.
