Heliopan has them; you just have to find someone willing to order 
them for you. I managed to find a shop in Germany that would do it 
for me and ship them to me; it cost a lot less than ordering them 
through a store here.

The other option is to use a 49mm filter, drop it in and shoot away. 
Series filters go by a simple formula: square the series number, and 
you're pretty close to the filter diameter in millimeters. Well 
actually, it only works for a couple of sizes, but the others are 
close. Series 7 is one that works.
