How to Tighten Rings on Canon Lenses
Take care when tightening the ring to not damage the camera. (film-camera on camera-bag image by Andrii Oleksiienko from

When working with Canon cameras the ring around the lens can become loose over time. For some it does not pose a problem, but some may find it aggravating and bothersome. Fixing the problem is relatively easy, but it may void any warranty that you have, so check with the manufacturer or retailer before attempting the repair.

  1. 1

    Remove the rubber ring that is used to focus the lens. It will peel off, but take care as it could easily tear or break.

  2. 2

    Rotate the ring that is on the lens of the camera. There is only one ring that is actually attached to the lens itself, the other rings are attached to the camera and are behind the lens. Line up the screws on the lens with the access holes that are on the ring.

  3. 3

    Screw the spacers that control the amount of space that is located between the ring and the barrel. The spacers are located between the ring and the barrel. Do this in small increments so as not to over adjust the screws. Tightening the screws will keep the barrel of the lens from shifting, which is known as barrel creep. After each incremental turn, put camera back together and check to see that the barrel is no longer shifting on its own. If the lens is not shifting, but is hard to adjust, you have overtightened it and will need to turn the screw in the opposite direction. Loosening the screws will make the tension on the barrel tighter. Once you have adjusted the lens to your satisfaction, replace the rubber ring.
