Dampening ring for Schneider-Kreuznach Beaulieu-Optivaron

[Jonathan Chong]

Hey there,

I have a Schneider-Kreuznach Beaulieu-Optivaron f1.4/6-70 mm lens and once I remove the Reglomatic motors the aperture ring is really loose. I'm wondering if anyone knows how to give the aperture ring more resistance so that I can use it manually and keep the aperture in place without it being accidentally moved out of position. Is there a dampening ring that can be installed on it or any other tricks? Thanks

Why did you remove the motor anyway? If you need the plain C-mount-version, I would recommend buying it instead of damaging the Beaulieu-specific extensions that weren’t supposed to be removed.

Quite serious. I've used it to fix focus for timelapse. Gaffer tape is probably a more filmic answer, if you have some, because it doesn't shed adhesive.

Because I can't afford to buy another version.
