This small DLC Soft Shutter Release Button from RPS Studio works with Fujifilm mirrorless cameras, the Nikon Df DSLR, and Leica M, as they all accept a standard shutter release. Once it is screwed into the shutter release socket, the DLC Soft Shutter Release enables enhanced tactile response and reduces camera movement. Its 1/2" button diameter provides a low profile method to a softer and lighter means of releasing the shutter.
