Instruction:

• If you own a Canon  EF 70-200mm F4, EF 200mm F2.8, EF 70-200mm F4L IS, EF 300mm F4L, EF 400mm F5.6L, EF 80-200mm F2.8L Lens, you own one of the best. To make either of these lenses even better, add a Canon Tripod Mount Ring 
• The Canon Tripod Mount Ring main purpose is to provide a better balance when mounted on a tripod. The 70-200 f/4 lenses do not require this ring to be mounted on a tripod - the camera body tripod insert can be used. But, this setup is front heavy. A top-notch ballhead can handle this load, but a lesser one will drop some amount after it is tightened. Care must also be taken to not tip the off-balance tripod forward. By moving the tripod mount to a centrally-positioned tripod ring (collar), balance is restored
• The advantages do not stop here. Since the tripod ring freely rotates, a nice amount of setup flexibility is gained. With the Canon Tripod Mount Ring in use, switching from horizontal to vertical orientation is fast and easy. Otherwise, a major tripod head adjustment is required (such as dropping a ballhead into the drop-notch)

• The thumbscrew tightens/loosens the tripod ring friction as needed. Simply rotate the ring to the desired position and lock it tight. If not needed, rotate the ring to an out-of-the-way position when not in use. Alternatively, loosen the tripod ring and pull out on the thumbscrew to completely release the ring from the lens. This release is accomplished via a hinge (noticeable in the pics). A hinged design allows the Canon Tripod Mount Ring to be removed without the need to unmount the lens from the camera
• A tripod ring allow various accessories to be attached to the lens - flash brackets being one of the most popular. I use a Wimberley P20 Lens Plate on my Canon Tripod Mount Ring. This allows me to quickly mount the lens to any common Arca-Swiss-compatible quick-release clamp (Arca-Swiss, Wimberley, RRS ...) on a ballhead, monopod clamp, flash bracket
• At one point, Canon had two Tripod Mount Ring A (W) models and one (B) model (W = White, B = Black). Both (W) models are shown in the pictures below, are interchangeable and are basically the same in their functionality

How to Use a Lens With a Tripod Mount:



A tripod is a necessity for the serious photographer. Old-style tripods were not flexible because they required a tripod mount directly onto the bottom of the camera. New tripod mounts, made especially for digital cameras, provide much more maneuverability while keeping the lens stable in its center of gravity. Today's tripod mounts, made of plastic in contrast to the old metal ones, allow you to alternate between vertical and horizontal shots with an easy adjustment to the tripod, not to the camera.

• Research the right kind of tripod mount for your lens before you make such a major purchase. Make certain that the weight and substance of the mount matches that of the lens.
• Calibrate your lens to the movement of the tripod mount before you begin a photography session.
• Weigh your lens and compare it to the weight of the tripod mount to make certain that the mount will hold it securely.

Tips & Warnings

• Make certain that your lens is attached firmly to the tripod mount before you attempt any movement. Always use two hands in such endeavors to protect your expensive equipment from being damaged if it becomes unfastened or is dropped.
