Minolta 28mm f2.5 MC W.Rokkor-SI
The Minolta 28mm f2.5 MC W.Rokkor-SI lens is a wide angle lens for Minolta MD mount 35mm SLR cameras. Smooth focusing, clean diaphragm, and only minor dust in the optics- but there is some yellowing. In case you’re wondering why there’s some yellowing, it’s because this lens has some lightly radioactive glass elements. Don’t worry, you’ll be fine (do not eat the lens), but worth noting.
