I am looking to find more about this brand that put out some lenses at some point - Gemini. Anyone knows anything about them? I haven't been able to find much. An older thread mentioned they are an importer, but then I'm curious who they contracted with for manufacture. They're listed on the wikipedia list of K-mount lenses: http://en.wikipedia.org/wiki/Pentax_KAF2_mount#Gemini. Also, to make this post a bit more useful, this is an interesting link I found about 3rd party manufacturers with lots of interesting historical tidbits: http://bbs.dartmouth.edu/~fangq/blog/index.cgi?note/photo/3PartyLens.
