The TC-DBC Tripod Collar from Vello is an easy-to-use tripod collar that's made specifically for the Canon EF 100mm f/2.8L Macro IS USM lens. The collar improves stability by redistributing the camera and lens weight. Rotating your camera from vertical to horizontal orientation is fast and effortless, and the vertical and horizontal marks on the ring assures that your camera is always in perfect alignment.
The foot of this lens ring features Arca-type dovetails, making it compatible with many tripod heads without the need to add a quick release plate.
