This large Dot Line DLC Soft Shutter Release Button works with Fujifilm mirrorless cameras, the Nikon Df DSLR, the Leica M Digital Camera, or any camera that accepts 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 5/8" button diameter provides a low profile method to a softer and lighter means of releasing the shutter.
