I'm in the midst of gathering information for a future post and I've hit a stumbling block. I've always assumed that there was a Japanese lensmaker in the 1960's called Komine; many Vivitar lens, for instance, are attributed to this manufacturer. However, the deeper I dig, the less I find. There seems to be several hints that Komine was somehow involved with the Nittoh Kogaku company who made made the "Kominar" series of lenses, but I can find nothing to substantiate this. Can anyone supply some information establishing that there was indeed a lens manufacturer called Komine, and has anyone ever seen a lens bearing this name either as a brand or as a manufacturer? Any help would be appreciated.
