The Takumar is the name of a wonderful lens, that the previously Asahi Optical and now Pentax, gave to its lenses.
I bought one for 3000 yen ($33) in a shop in Akihabara (Techno district of Tokyo) that sells junk stuff. The glass is in perfect conditions and the big aperture plus the good ISO performance of the Pentax K-X makes a good combination for nocturne urban photography.
