Originally posted by twilhelm Not too long ago I purchased a Voigtlander Bessa R with the intention of having a camera I could purchase and use Russian made M39 lenses on.
Browsing through this thread I see that many of you are using these lenses on the Pentax DSLR's.
My question is what adapters are you using to mount M39 lenses, and what potential problems are there?
I would love to use them on my *ist DL or better yet my K10d!
There are two types of FSU 39mm screw mount lenses. The first type is LTM and were designed for use on rangefinder cameras such as the Zorki, FED and your Bessa. They cannot attain infinity focus with your Pentax dSLR, though they are popular with the EVIL camera users. The second type was designed for use with early Zenit SLR cameras. The M39/Zenit many be adapted for use on the Pentax system. It is important to know which lenses you are dealing with, though the task is made somewhat easier because there is not a lot of overlap of lens names between the two systems. There are Jupiter-9 85/2 models in both mounts, but I think that may be it.
The short story is that your Bessa R lenses will not work for general shooting, though my understanding is that the Jupiter-8 in LTM makes a decent close-focus lens on an SLR!
