This is a clip that locks the Sony 4K camera's viewfinder into the open/on position, keeping it from being pushed back in until clip is removed. No more missed videos because someone accidentally knocks your viewfinder and turns your camera off. This will also keep you from having to expose the fragile and expensive LCD to the elements during your skydives. The leash on the right side helps keep the clip on your camera for easy locking/unlocking of view-finder. Fitted and tested on the Sony FDR-AX53 (pictured), but is also compatible with FDR-AX40/AX55/AXP55 cameras.
