Hi
I have bought a Bessa I in very good condition, but the lens has a problem. The rear element is loose in its ring (the distance between the glass and the ring is abt 1mm) resulting in out of focus images. Does anyone know how it was held in place? A rubber or metal ring perhaps?
Any advice would be appreciated.
Regards
Michael

Solved it with help from a photo.net user.
The retaining ring could be tightened with a rubber tool (vacuum pad? from Japan Hobby Tool)
