The top handle is designed for SHAPE A7S II, A7R II, and A7 II cage and features the unique patented SHAPE red Push-Button technology. SHAPE is well known for its patented Push-button system, now used by so many professionals in the industry. The technology was developped to give filmakers quick and easy adjustment. By simply pressing the button, you are allowed a 360-degree rotation to place the top handle in the best position for your use. Push, adjust, release, and then its lock. It is designed to be installed on the hot shoe adapter on our cage and fixed with a screw. The handle sides features several 1/4-20 and 3/8-16 threaded holes for accessory attachment.
