Konica's standard Hexanon fifty — the 50mm f/1.7 for AR mount, a classic fast prime.
The Konica Hexanon 50mm f/1.7 is a fast standard prime from Konica's Hexanon lens range for the AR-mount system. The f/1.7 maximum aperture places it between the common f/1.4 and f/2 standard primes, providing strong low-light capability.
The lens delivers 50mm at f/1.7 maximum aperture with Konica AR bayonet coupling, manual focus, aperture ring with AE indexing, and full-frame 35mm coverage. Hexanon optical quality in the standard prime range is consistently well-regarded.
The Hexanon 50mm f/1.7 is among the most sought-after AR-mount lenses for adaptation to modern systems, offering fast aperture and Konica's characteristic rendering at a moderate price. It is well-suited for street, portrait, and available-light photography on adapted mirrorless bodies.
Check aperture blades for oil contamination at f/1.7 where clean blade operation directly affects bokeh quality. Test focus ring for smooth, precise travel. Inspect Hexanon coating on all elements. Verify Konica AR coupling engages and locks positively.
