The FreeWave Fusion Pro Wireless Flash Trigger and Remote Control for Canon DSLRs from Vello is a versatile, reliable remote control kit that will trigger off-camera flash units and studio lights from up to 600' away. It can be used to configure up to three different light groups, which can be triggered individually or simultaneously, for a total of seven different combinations, using its multiple groups feature. Simultaneous triggering of multiple lights requires separate purchase of additional FreeWave Fusion Pro Receivers.
The FreeWave Fusion Pro also provides the convenience of a wireless camera shutter release, ideal for photographing wildlife, and also for macro and close-up photos or long exposures, where the slightest camera movement can ruin a picture. Working on the 2.4 GHz frequency gives you reduced radio interference and an extended range up to 600', and since radio signals pass through obstructions you don't need to position them in line-of-sight. Four RF channels are available to prevent interference from other users.
The FreeWave Fusion Pro is compatible with most cameras, flash units, and studio lights. The transmitter connects to the hot shoe of the camera. In case the hot shoe is needed for another function, the transmitter can alternatively connect to the camera's PC plug via its 3.5mm sync plug (PC cable not included). The transmitter also features a top hot shoe, which fully supports E-TTL metering when used with Canon TTL compatible components. This allows you to keep a TTL flash mounted on top of the camera, while using the transmitter to control off-camera flash units (in manual mode) via radio signal.
