Hi All,

I have an old (1970’s) 150mm Schneider Xenar lens F4.7 with a Compur 0 shutter. Until now it has been fine, but now the shutter no longer opens on B. All other speeds appear to work fine, and the shutter cocks OK, but when I set it to B the shutter just ‘clicks’ but it doesn’t open at all.

Before I condemn this aging piece of clockworks to the grave, is there anything I can do to remedy this situation ? I find it difficult to use this lens inside for naturally lit still subjects as I need the depth of field from long exposures.

Many thanks
Steve
