Quick-release belt-grip kind of like a simplified version of the B-Grip. Very useful to have the camera ready without occupying your hands and without having the camera shake around and potentially hit things and get damaged as on a belt. This makes use of the camera_plate from my 3d printed shoulder rig -design. Blog post: marcuswolschon.blogspot.com/2011/07/3d-printed-camera-belt-clip.html
