Summitar Uv filter

[The Kook]

I am looking for opinions on a UV filter system for my Summitar 50 and Steinheil 135. I am looking to get the adapter ring to use newer filters. What are your experiences? I am gathering that the adapter ring is the best as it allows the use of newer filters. What is the product code? Thanks for any help.

I've heard from some of the experts that a 36mm -> Series VI adapter would do for the Summitar. I would also like to hear if anybody can validate or correct my statement. I would really like to use a MRC UV filter for my Summitar.

I have a K2 Leitz filter on it; they are rather hard to find in excellent condition for under $30.
