Minolta's economy late MD standard — the 50mm f/2, a common compact kit normal from the early 80s.
The Minolta MD 50mm f/2 is a standard manual-focus lens for Minolta reflex cameras from the final MD generation of the early 1980s, when Minolta dropped the Rokkor name from most barrels. As the economy normal lens in the mature MD system, it was frequently supplied as the kit lens on entry-level Minolta bodies of the period.
This is a manual-focus standard lens with a 50mm focal length and a maximum aperture of f/2, from the last MD line. Only the focal length and aperture are affirmed; other construction figures are not confirmed here and are omitted rather than guessed. It sat below the f/1.7 and f/1.4 50mm options as the affordable normal.
The 50mm focal length gives a natural perspective close to human vision, making it a versatile everyday lens for general shooting, casual portraits and street work. A maximum aperture of f/2 provides useful low-light latitude and modest background blur while keeping the lens very compact and light.
On the used market this is a very common and inexpensive final-generation MD standard, popular as an affordable entry into adapting vintage glass to mirrorless. Given its age, inspect for haze, fungus and separation, confirm the aperture is dry and snaps cleanly, and check the focus helicoid runs smoothly. Look over the coatings for cleaning marks before buying.
