Tripod Mount Ring for Canon 70-200mm f/4 (White)
Tripod Collar
The white Tripod Mount Ring for Canon 70-200mm f/4 allows you to balance your lens when using it with a tripod. Rather than allowing your Canon 70-200mm f/4 lens to hang off the front of your camera, secure it directly to the tripod using this mount. It features a metal construction, and the UNC (Unified National Coarse Thread) is 1/4.
