The JJC JM-II series Radio Frequency Wireless Shutter is designed for most DSLR and SLR cameras that have a remote socket on the camera body. The system works at 433MHZ frequency and has 16 available channels. The JM-II receiver simply attaches to a compatible camera's accessory shoe, and then just connects the supplied JJC receiver cable to the camera's remote socket. The receiver is powered by one piece of CR-2 lithium battery while the transmitter is powered by one piece of 23A battery.
Most importantly, our JM-II transmitter is able to fire multiple receivers at the same time. The receiver itself with the connecting cable can be used as a Wired Remote Switch, then half press to focus, full press to take a photo. All these features make it good for eliminating camera shake in long exposure photography.
