Jerry / Todd , it sounds like another thing to deteriorate or go wrong,
yet I have not heard of any such problems.

Todd,
Thanks for the clarification. I'm glad that I didn't check my 2.8F first.
I see now that the rubberized ring acts as a displacement diaphragm, or membrane to affect an internal light seal.

Jerry,
The 2.8 A and B have felt lining the inside of a metal ring that forms a light trap as the taking lens moves in and out. The taking lens moves back and forth in the felt surround. The 2.8 C, D, E and E2 have a rubberized cloth bellows in place of the felt light trap. The rubberized cloth bellows can be hard to see because there is sometimes a lens shroud on the back element of the taking lens that obscures the bellows. The E3 and F have the felt surround.
In the 3.5 cameras, the felt surround is used up until the MX-EVS. The E, E2 and early F (ring shutter) have the rubberized cloth bellows and the later F and E3 cameras have the felt surround again.
