Benefitting making long exposures with the Olympus OM-D E-M1 Mark II and E-M5 Mark III mirrorless cameras, the RM-CB2 Release Cable is a remote shutter release that helps to prevent camera shake when working atop a tripod or other support. This cable release connects directly to the camera via a 2.5mm mini stereo jack, allows you to remotely release the shutter, and has a locking function for making bulb exposures.
