The JJC JF-G1P/JF-G2P Wireless Flash Trigger & Remote Control is a versatile, reliable remote control kit that will trigger off-camera flash units and studio lights from up to 300 feet away. The JF-G1P,G2P 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 2.4GHz 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.
Since the JF-G1P/JF-G2P does not transmit TTL settings, use of a flash or light unit with full manual control is recommended. You will need to set the power output manually.
