In good condition and was the lens I always went to. I however never utilized the leaf shutter.

120 Backs:
Both work great and are in good cosmetic condition. On of the inserts however a spring is loose and therefore one of the tabs that holds one of the spools is a little loose, but hasn't ever caused any issue.
$40 for the one with the insert that has no issue (also with cap), $30 for the one that does.
