Most cameras these days offer some kind of built-in WiFI or Bluetooth control that allows you to fire your camera from an app on your smartphone. But not all of them do. The Ricoh GRII is one of those cameras that actually does offer some remote control via an app or USB remote, but sometimes you still want that tactile feel of pushing a shutter button, and the immediate response it gives.
One GRII owner, Steloherd, has created his own method of firing the camera’s shutter via a traditional mechanical shutter release cable. It attaches via the camera’s hot shoe, and then the cable just screws into the top to push down the regular shutter button.
