Measure the outside diameter of the lens and send me a PM. I may be able to help you. I still have a a large box of series filter holders, adapters, etc. If I have something for you, I'll give it to you in return for a cup of coffee. That way I get to meet another APUGger.
My Mess Ikonta could use some filtering, do you know what size the 10,5cm Tessar 3.5 takes?
