  5. Hi, everyone! I'm trying to restore a Mamiya c 330f and it's lenses, when, during the disassembly of a 180mm f4.5, i found one of it's internal elements damaged. After some calls, i found a lens builder that can make another element, but i have to tell him what kind of optical glass were used in that piece. So... does anybody knows the type of glass were used in the internal elements of a Mamiya sekor 180mm f4.5 (It has four elements in three groups and the piece i want to do is the second element from the camera to the front element). Thanks you, guys!!!!
