I have just bought a Werra wide-angle Flektogon lens (2.8, 35mm). The exchangable Werra lenses couple to the rangefinder in the body - a pin slides out as the focus is altered. But oddly, on this Flektogon, the pin works between 10ft and infinity, but won't move when I focus any closer than 10ft. Is this by design? It's hard to think of a failure which could make the pin only work half way. Unless someone knows different?
Any ideas about what might be wrong, or advice on how to disassemble and fix gratefully received! |

As you say, the rangefinder is actioned by a pin. At the lens end such pin rides on the progressive cam on the reverse of the lens module. Your problem sounds to me as though the lens has been serviced and the focusing helix reinstalled incorrectly.
That is to say - the pin is now riding on the wrong part of the cam for any given focusing point.
An alternative explanation could be that the pin-receiver quadrant as under the camera's top-plate, is wrongly adjusted.
This too woud produce incorrect focusing. |
