While we're on the topic of exotic filter mountings for Leica lenses, 
I thought I'd note that B+W offers a 41/52 step ring which allows the 
use of readily available polarizers and color correction filters on 
the 65 Elmar.  The ring is a special order item from B&H, and 
delivery, in my case, took about 8 weeks.  But now I'm set to do some 
copy work with the Visoflex.
