Minolta's late MD macro — the 100mm f/4 MD Macro, a flat-field close-focus tele from the early 80s.
The Minolta MD Macro 100mm f/4 is a short-telephoto macro 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. The Macro designation marks it as a close-focusing lens optimised for flat-field, high-magnification work in the mature MD system.
This is a manual-focus macro lens with a 100mm focal length and a maximum aperture of f/4, from the last MD line. Only the focal length and aperture are affirmed; other construction figures, and whether a matching extension tube was needed for full 1:1 reproduction, are not confirmed here and are therefore omitted rather than guessed.
The 100mm macro focal length gives a comfortable working distance from small subjects, valued for close-ups of insects, flowers and detail where the extra standoff avoids disturbing the subject or casting shadows. Its flat-field correction also makes it well suited to copy work, and the length doubles usefully as a short portrait lens.
On the used market this is a well-regarded final-generation MD macro sought by collectors and close-up shooters adapting vintage glass. Given its age, inspect for haze, fungus and separation, confirm the aperture is clean and responsive, and check the long focus helicoid moves smoothly throughout its extended travel. Use an adapter for mirrorless mounting.
