The Wireless ShutterBoss III with Release Cable for Fujifilm Cameras Kit from B&H expands the compatibility of your remote switch by pairing it with a 2.5mm shutter release cable compatible with select Fujifilm cameras. The cable connects the receiver to the camera, enabling wireless communication with the transmitter for remote shutter release. Two other release cables, one for Nikon 10-pin cameras and another for Nikon DC-2 cameras, are already included with the remote switch for additional compatibility.
