Konica · Konica AR · From 1973
Konica's fast fifty replaced the 57mm f/1.4 soon after the Autoreflex T3 appeared in 1973. It's a seven-element, six-group lens with eight aperture blades, and every version focuses to 0.45 m. The first copies carry a green EE mark on the aperture ring and later ones a green AE mark, and both of those click at half stops and close to f/16. Around the FS-1 of 1979 Konica reworked the barrel. The later version closes to f/22, clicks at full stops only and is lighter, while the glass stayed the same, so the choice comes down to feel. Konica collectors rate it a hair behind the famous f/1.7 for sharpness, which is high praise, and the extra two-thirds of a stop buys you shallower focus for portraits. You'll see it less often than the f/1.7, but it isn't rare. On a mirrorless body it adapts with any plain AR adapter.
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
Three versions share the same optics. The first has a green EE mark, the second a green AE mark, and both stop down to f/16 with half-stop clicks and weigh about 290 g. The third, from around the FS-1 of 1979, stops down to f/22, clicks at full stops and weighs about 265 g. Sources disagree on when it ended, between 1984 and the end of Konica SLRs in 1987. Its predecessor is the Hexanon AR 57mm f/1.4.
The usual age faults apply here, mainly haze, fungus and oily aperture blades. A stuck AE lock button leaves the aperture ring parked at its smallest aperture.

Buying guide
We'd buy the Japan dealer's copy graded N MINT at $104 delivered, right at the $105 median, or pay $155 for one titled CLA'd if you want it cleaned before you shoot. There are at least 38 for sale and most ask $75–150 delivered, while US sellers start at $45 for copies with no grade or test claim. Early EE and AE copies close to f/16 and click at half stops, and the later, lighter version closes to f/22 with full-stop clicks, but the glass is the same, so pick by feel and condition. Ask for a flashlight photo through the back for haze or fungus, one of the blades at f/8, and for the ring to be turned out of the green AE click to show the lock button releases, and skip the $233 copy at about 2.2 times the median. It needs a Konica AR adapter, and the model page lists the adapters by camera.
