Flange distance for M39 is 28.8mm... Are you sure it has 28.2mm?

 

Which reminds me, I still have some B/W ISO 400 film in my Agfa Record II with Agfa Solinar 105mm f4.5 (about 45mm f1.9 FF equivalent). If I remember correctly, I still have two frames left  :ph34r:

 

More comparable to your "new" Ruski, I have a Kodak Retina rangefinder which should still work fine. Fixed 50mm lens.

Hi BC..

 

..You know me BC, in between looking up the flange distance and writing it down I always make some sort of  error.....yes 28.8mm,........then it's just a question of finding an adapter for the Pentax K mount for my very appropriate K01 with focus peaking........I will check it out....
