But now it's time to put a follow focus on it. As anyone who owns this lens will know, the focus ring has old-school ridges that make it tricky to put a focus gear on, but right underneath it is a "smooth" area that I am convinced could be made to turn with my iDC System Zero follow focus (if not by itself, then with a standard office ziptie or something similar).

The problem is, the shape of this device puts the rubber about a millimeter shy of where it needs to be. It's so close, but it doesn't quite touch:

If I could find a way to add even 1/8 of an inch to the lens, I think that it could make contact and possibly work. But my problem is that all adapters tend to do something. I want one that does not do anything. Since it's a manual lens to begin with, I won't be losing any functionality.

Does anyone know of anything like this, or another workaround?
