Konica · Konica AR · 1965 to the late 1980s, in several versions
Konica made a 28mm f/3.5 for the whole life of its AR mount, starting with the Auto-Reflex in 1965, and redesigned it more than once, which is why listings vary so much. The first was a preset lens. The auto-aperture Hexanon that followed used seven elements in seven groups, first with a chrome ring and a yellow EE mark, later all black with a green AE mark. Around 1978 Konica switched to a smaller five-element, five-group design, and from about 1980 it closes to f/22 and has a rectangular AE lock button. Every version focuses to 0.3 m. Konica collectors rate the last seven-element version as the best, and say the switch to five elements lost a little quality. In some markets Konica sold it in kits with a body, a fifty and a 135mm, so it's one of the easiest Konica lenses to find. On a mirrorless body it's a compact, sharp 28, if slow at f/3.5.
On a mirrorless camera
It’s a Konica AR lens, and its mount sits 40.5 mm from the film. Every mirrorless mount below sits closer than that, so a plain adapter ring fills the gap and the lens still focuses to infinity. On a smaller sensor it frames tighter, like a longer lens.
Versions
The first 28mm f/3.5, from 1965, is a preset lens with a 58mm filter and seven elements in six groups. The auto-aperture Hexanon that followed has seven elements in seven groups and closes to f/16, first with a chrome ring and yellow EE mark, then all black, then with a rubber focus ring and green AE mark. Around 1978 it became a lighter five-element, five-group lens, and from about 1980 that one closes to f/22 with a rectangular AE lock button. The Hexar AR 28mm f/3.5 is a separate budget lens, reportedly made for Konica by another maker.
Most disappointments come from getting a different version than you expected, since the 7-element and 5-element lenses look alike. The big front element isn't recessed, so look for scratches and cleaning marks, and use a hood to keep contrast up.

Buying guide
We'd buy the US copy titled tested and clean, with a rear cap and case, at $60 delivered, under the $65–120 band, or pay $91 for one with caps and Konica's own hood, worth having on a lens whose big front element isn't recessed. There are at least 60 for sale, mostly from US sellers at $45–113 delivered, often with caps, a case or a hood. A 16 as the smallest aperture means the older 7-element lens that Konica collectors rate higher, and a 22 with a rectangular AE lock button means the late 5-element one, so look at the aperture ring in the photos. Check the front glass for scratches, ask for a flashlight photo through the back and one of the blades at f/8, and skip the $220 Japan copy at about 2.4 times the median. It needs a Konica AR adapter, and the model page lists the adapters by camera.
