The Delkin Devices Fat Gecko DSLR Camera Mount Quick Release Accessory features a quick release base plate that fastens to your DSLR camera. Then, the base plate slides into the adapter plate, which features a push button key to lock the camera into place. This simple push and release function makes for ultra-quick removal of your camera from the Fat Gecko Mount during shoots. Plus, the accessory even features dual liquid levels that help you set up precise angles, and the sturdy base / adapter plate edges and push button key prevent your camera from slipping out of the mount. For added flexibility, the Mount features a 3/8-16 thread on the bottom with a 1/4-20 reducer bushing - meaning it can fit both standard sizes.
