LTM Nokton mount problems- too far

[puqq]

The 50mm 1.5 Nokton seems to go a little too far into the mount of my Bessa R (perhaps by 10-15 degrees of a turn)- see picture. As a result the lens sits too close to film. The rangefinder seems to work fine, but the infinity focus is reached when lens scale is around 3m, and closest focus is around 1.5m, rather than 0.9m.

How could I fix this problem?

Are your pics out of focus?

It's quite normal for index lines not to be right on top of the lens. If the RF works, I suspect you have no problem at all.

On re-reading, I assume your pics ARE out of focus. But I'd still be interested...

Cheers,

R.

Thanks. The pics are in focus, just that I can't reach the closest focus of the lens (~1.5m instead of .9m)

Haha 🙂 Thanks. Piece of cake.
