2 Pack Wireless Flash Trigger and remote shutter for Canon and Nikon Presenting the Altura Photo Wireless Flash Trigger & Remote Control 2 pack is a versatile, reliable remote control kit that will trigger off-camera flash units and studio lights from up to 100 feet away (30meters). Also provides the convenience of a wireless camera shutter release, ideal for photographing wildlife, and also for macro and close-up photos, where the slightest camera movement can ruin a picture. Working on the 433MHz frequency gives you reduced radio interference and an extended range - you don't need to have line-of-sight alignment, either, as radio waves will pass through walls, windows and floors.
