The FreeWave Plus is a complete lightweight remote control outfit that provides a way to trip your camera's shutter while avoiding any possible unwanted camera movement. The FreeWave Plus works in either wired or wireless mode. This is ideal for photographing wildlife, and for macro and close-up photos or long exposures, where the slightest camera movement can ruin a picture.
With the dual function release, press halfway to focus, then press all the way to trigger the shutter. A four-second delay function makes it easy to produce self-portraits. Working on the 2.4GHz frequency gives you reduced radio interference and an extended range (up to 320' (100 m))--you don't need to have line-of-sight alignment, either, as radio waves will pass through walls, windows and floors.
