Minolta prime lenses had a well-earned reputation for optical and construction quality, and many older Minolta prime lenses are still sought today, by owners of the Sony Alpha digital SLR system. (Sony bought out all the Konica Minolta lens and camera designs in 2006, ending a long history of Minolta as a separate company, but carrying forward many of the excellent optical designs and camera technology that Minolta had developed over the years.) See below for models of Minolta prime lenses.
