FotodioX Tripod Collar for Canon EF 70-300mm f/4-5.6L IS USM Lens

The Tripod Collar by Fotodiox attaches your Canon EF 70-300mm f/4-5.6L IS USM 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.
