SINAR Schneider Symmar -S 210mm/f5.6 lens in DB Mount - DAMAGED Filter Mount
SINAR Schneider Symmar-S 210mm/f5.6 Large Format lens in SINAR DB mount lens panel. As this is for use on a SINAR with a behind the lens shutter this shouldn't be a problem as you probably use the SINARswing in filter and/or drop in system.
