The Phottix wired remote control is a compact remote control that replicates all the functions of the camera shutter button. This remote control makes it easy to take photos with long exposure times. A half press of the shutter button will activate focus, while a full press will trigger the shutter. The shutter button can be locked for shooting in bulb “B”. Very compact, the remote control is extremely robust and light.
