                    While placing the ring (barely any force) on the lense it snapped. Had to repair/reinforce it with a piece of thin plastic and epoxy.

                      Two things I don't like about this product:
                      1.- It doesn't fit perfectly into my Canon Lens (24-105mm), although it says it would in the specifications.
                      2.- The ring didn't come with the stop that is shown in the picture.

                      Still, it does its work.

                          Comments about Cavision RFGR80 Follow Focus Gear Ring:

                          Sadly it seems to be practically impossible to match up these gear rings with Canon lenses. I tried many different measurements and gear rings and still have not found a ring that works well with my 17-40L, 85 1.8, or 50 macro. I am using foam and electrical tape to pad out the much too large gear rings for a frustrating but 50% usable follow focus system.

                          Why not specify what gear rings work with what lenses? Come on, Cavision.

                          Good ring but can be tricky to size

                                These rings work fine, but I found them a little tricky to size to the lens. I generally needed to go up one size based on my measurements. In addition, there are gaps between some sizes, so I had to buy the next size up and shim a couple of lenses. All of my lens are Canon lenses for the 7D. Note that none of the rings I have gotten have the stop included.
