I have recently purchased an RF 100-500 lens and am very happy with its performance so far. However, the tripod ring does not seem to tighten sufficiently to prevent the lens/camera from rotating. Any advice/solution would be greatly appreciated.

Just got my new lens 1st of the month, I'm having the same issue; hate to have to use pliers/vice grip to tighten as that would certainly disfigure the quality finish, suggestions?

This issue is a recurring topic in these forums. It seems that you must close and align it caarfully when you replace it after removing it. Also, it does not take more than a full turn to loosen it sufficiently for it to rotate. It seems that over loosening it is where most people are getting into trouble.

The knob is spring loaded. Taking off: Make sure you are pulling on the knob as you loosen it while also pulling up on the clamp side. Reinstalling: Pull on the knob before closing the clamp, then tighten the knob once the clamp is fully aligned. The knob shouldn't take more than your fingers to tighten. Not pulling on the knob while closing and opening the clamp can damage the knob or the clamp area where it contacts. Inspect the knob and clamp and make sure there is no damage to either. If you suspect damage, replace the mount.

Thanks for the response and the pictures. I am familiar with the spring action of knob. There does not appear to be any damage on either side and the ring seams to line up properly on the lens when attached. I have tried several times to remove and reattach however when mounted to the tripod it is fairly easy to rotate the camera/lens unit. This may be advantageous if someone wants to quickly change from landscape to portrait but I do not believe this is the intent. Lens stability is paramount. I will call Canon support and see what they suggest. Right now it would be very inconvenient to be without the lens if it needs to be returned. I Purchased it last November so it is still under warranty.

Thanks for posting these images. I've been meaning to do it myself. I'll try and add some of my own this evening.
