This Wireless RF (Radio Frequency) Shutter Release Kit enables you to trigger the shutter in both wireless and wired modes. The system produces a coded radio signal that works indoors, outdoors, around corners and even through walls! It has an effective working range of up to 100 feet. The RF kit also provides 16 multi-coded channels, giving the photographer plenty of combinations to work with, without interfering with anything else using the same frequency. To use the RF kit in wireless mode, simply attach the receiver (the blue LED light will blink to indicate that the receiver is on) to the camera, then use the handheld transmitter to trigger the shutter release. Using the RF kit in a wired mode is easily done by attaching the receiver onto the camera, then pressing the shutter release button located on the receiver.

The cord on the receiver is approx. 3ft in length, allowing for ample room for the photographer to move around. In both wired and wireless modes, press the shutter release halfway to activate the cameras auto focus (a red LED indicator on the receiver will light up to confirm), then press the button fully to take a picture. High quality and durable design make this Wireless RF Shutter Release Kit stand out amongst the competition of inexpensive and mediocre kits, be cautious when purchasing extremely low-priced wireless RF kits from overseas sellers.
