Minolta Rokkor PF 58mm f1.4 brand_Yashica the camera itself runs onThe Minolta Rokkor PF 58mm f1. 4 is a fast Minolta MD mount lens. Has some dust, a minor bend on filter ring (doesn't impact ability to mount filter) and small circular etching on the edge of the front element (also doesn't show up on images). The focus is smooth and diaphragm blades are clean. Not perfect, but a really nice lens all the same.
