You have this one? I got the knob off and it turns freely but I don't see how to get it off. It has ridges on both sides and the thing doesn't open more than half an inch. I am wondering if I am missing something obvious

anyone ever take the tripod collar off the 300mm F4.5 AI or AIS? It is a heavy duty collar and I thought it would slip off once I loosened it but it doesn't have much give. I am wondering if I have to remove the aperture ring.
I have one and the collar is easy to put on or take off! Your knob may be a little finicky but maybe a bit of penetrating oil will help. Good luck!
