The TR-III Tripod Collar by JJC attaches your compatible Canon telephoto lens to a tripod or monopod while stabilizing it. A locking knob helps safely secure the collar to your lens. The knob can be loosened, allowing you to turn your camera from landscape to portrait mode without removing your camera from your tripod or adjusting your tripod head. The collar is coated with a matte white finish.
Compatible with: Canon EF 70-200mm f/4L, Canon EF 300mm f/4L, and Canon EF 400mm f/5.6L lenses
