Thanks. The lenses I have with these seem to center on 1.5-1.7m (35/1.4 ASPH, 21-35 dual, 40 Rokkor). I was actually thinking of putting one of these on a 90 M-Hexanon, since it has a short throw, a light action, and the Heavystar tab just fits aft of the knurled part of the focus ring. Needs some compression to make contact, but it would be kind of cool if it worked...
