Minolta's MC macro — the 100mm f/3.5 MC Macro Rokkor, a flat-field close-focus tele from the early 70s.
The Minolta MC Macro Rokkor 100mm f/3.5 is a short-telephoto macro manual-focus lens for Minolta reflex cameras from the MC generation of the early 1970s. The Macro designation marks it as a close-focusing lens optimised for flat-field, high-magnification work, and MC the meter-coupled series. It was Minolta's medium macro of the era.
This is a manual-focus macro lens with a 100mm focal length and a maximum aperture of f/3.5, from the meter-coupled MC line. Only the focal length and aperture are stated as verified; other construction figures, and whether a matching extension tube was needed for full 1:1 reproduction, are not confirmed here and are therefore omitted.
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 MC macro Rokkor 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. Look over the coatings, and use an adapter for mirrorless mounting.
