Rei,

I'm pretty sure the glass from a 39mm filter and the Summitar filter  
is the same size. I'm not willing to take apart one of my Summitar  
filters but I will buy a bargain one and remove the glass. Bargain  
Summitar conical filters are in the $19-$20 range. Then I'll replace  
the glass with one from a 39mm cut filter. I'll report here in a week  
or so.
