This convenient release cable with a pin jack terminal (2.5mm diameter) features a bulb lock function convenient for long exposures. The connector features an L-shaped design to ensure a compact form when connected to the camera. 

The RM-CB2 cable release enables you to focus and trigger your camera without the vibration associated with using the shutter release button. This is especially useful for macro and micro photography, where it’s critical that the camera remains still.
