JJC ES-628 Wireless Remote Controller is designed for cameras with a remote shutter socket. The remote controller allows you to control the camera from afar when shooting, so it also prevents camera shaking. The unit includes three parts: transmitter, receiver and a connecting cable. It powers easily. The ES-628 controller can trigger the camera shutter at five modes: single shot, unlimited continuous shots, bulb shot, 3 continuous shots and 5 seconds delay shot. This system works at a 2.4Ghz frequency allowing the transmitter to trigger the receiver and then your camera shutter without direct line of sight up to 100 meters. The receiver has a universal 1/4"-20 tripod mount socket on the bottom, so you can even mount it onto a tripod.
