Posted - Jan 09 2010 : 7:10:39 PM Hi all I picked up a mint HELIOS-44M 2/58. here is my question. M42 mount? It will not thread onto my Pentax K-M42 adapter. It will thread onto a M42 body but not the adapter?

Posted - Jan 10 2010 : 09:37:03 AM well all my Pentax lenses work no problem. I have a couple of 3rd party lenses that work fine in the adapter also. Just not the Helios for some reason. The Helios works fine on 2 other M42 bodies. Must be the Pentax adapter has a real close tolerance. That's the only thing I can think of.

Posted - Jan 10 2010 : 05:03:34 AM Is the auto diaphragm pin on the bottom of the lens catching in part of the adapter? Perhaps in one of the cut outs that the removal tool fits into- it has happened to me- or possibly the thread of the adapter is damaged. I have 3 Infinity m42-k adapters and all work with every m42 lens I have, including the Helios 44-m
