Voigtländer Vito CLR shutter
I bought this Voigtländer Vito CLR for a song from a parts bin. Its shutter dial was stiff, so I dug in to find out why. A simple clean and grease of the helicoid has it working much more smoothly.
This seems to be a newer model CLR and the focus ring retaining screws are hidden under the distance gauge ring.
