several people have asked -- it takes a 50mm jam nut that i don't have, or you screw it into a lens board with that large of a threaded hole, such as the Durst the other one in my basement is on. Adorama has the jam nuts for $14.50 http://www.adorama.com/RDJN50.html
$130 to compensate for the jam nut issue?????
here's adorama's ad for the same lens, only newer. Note the astonishingly higher price from Adorama-- it is amazing they're not coming after me.
