Cameras Vello's FreeWave Plus Wireless Remote Shutter Release - 2.4GHz is a complete lightweight remote control system 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. LED indicators confirm pre-focus and exposure when in wireless mode. The FreeWave Plus is capable of multiple exposures with a single press of the trigger, and you can control the length of long exposures remotely, also. It can be adapted to work with virtually any major brand of camera--just switch the dedicated release cable. 2.4GHz Radio FrequencyReduced interference and improved wireless signal quality.Extended RangeUp to 320' (100 m) range.16 Possible ChannelsOne transmitter can trigger multiple receivers.Built-In AntennaDestruction-proof internal antenna.Dual-Function ReleasePress halfway to focus; press fully to trigger shutter.Delayed ReleaseFour-second delay function gives you extra time to get into position.Multi-ExposureTake multiple shots with one press of the trigger.Long ExposureControl the length of the exposure remotely.Multi-FunctionTrigger your camera wirelessly or wired.
