If you're handy with a dremel tool or have a lot of time and a file, it's very easy to craft a custom made tab out of 1/4" plexiglass. Contour it to the lens' focus barrel then contour it to your finger, smooth it out and stick it on with 3M outdoor use double sided tape and it's just an hour or so of work at a very small expense for the plexiglass.

I'm not sure I can find a small piece of plexiglass where I live, I'm thinking maybe doing it with epoxy, dead easy to mold.. might be this weekend's minichallenge 🙂
