A tripod collar or lens support ring is a detachable ring that fits around the middle of certain long, heavy Canon lenses. It provides a more balanced and secure way to mount the lens on a tripod for better stability, especially when shooting with a telephoto lens
- Improved balance: A tripod collar balances the lens over the tripod mount, reducing stress on the lens mount and camera body. This is especially important for heavier lenses.
- Easier rotation: With a tripod collar, you can rotate the camera and lens from portrait to landscape mode without having to loosen and retighten the lens on the tripod mount. This is much quicker and more convenient.
