Seikanon
Guantaray
Ricoh
Elicar
Kalimar
Sirius
Centon
Soligor
Pheonix
Just wonder if most of these lens were re-badged mirror lens from the same OEM.
I'm too new to mirror lenses to offer an opinion. Heres a site that has quite a bit of info and associated links. I suggest that anyone interested in such a lens do some research and then decide where to spend those hard earned $s. The Tamron that Ben has pictured is rated very highly. The Tokina gets good marks also. One of the newer lenses is made in Russia, Rubinar, i think and seem to be rated well but are in the $300 range from what i saw. i don't know what mount they use.
