The Dinkum Systems 1/4" Fixed Mount Base for Dinkum Arms provides an alternate way of attaching Dinkum's adjustable arms to cameras. A Dinkum arm normally attaches via a Dinkum Spring Clamp. The Clamp grips onto a camera handle or onto a rod and serves as a mounting base for the arm. As the alternative, the Fixed Mount Base simply replaces the Clamp, attaching instead of it onto the camera and serving instead of it as a mounting base.
It screws right onto the camera's handle by a 1/4"-20 screw, screwing in at the turn of a knob. You can also connect it to an accessory block or to anything else that accepts a 1/4"-20 screw. You can at all times keep it connected while mounting and dismounting the arm from it as needed.
Just like the Spring Clamp is, the Fixed Mount Base is compatible with all Dinkum arms except with COMPACT Lens Shades.
