Konica's telephoto for AR mount — the Hexanon 135mm f/3.5, a decent vintage telephoto.
The Konica Hexanon AR 135mm f/3.5 is a telephoto prime from Konica's own Hexanon lens line for their AR-mount SLR cameras. Konica's Hexanon lenses were the brand's first-party optics, generally regarded as high-quality and well-corrected compared to third-party alternatives in the AR system.
The lens delivers 135mm at f/3.5 maximum aperture with Konica AR bayonet coupling, manual focus, aperture ring, and full-frame coverage. Hexanon optical quality and Konica build standards were competitive with Nikon, Canon, and Minolta first-party lenses of the equivalent era.
Konica Hexanon lenses have a dedicated following among vintage glass enthusiasts for their rendering quality and build. The AR mount adapts readily to Sony FE, Micro Four Thirds, and Fujifilm X via available adapters, giving Hexanon glass a path to modern use.
Test Konica AR coupling and AE lever operation. Check aperture blades for oil contamination — common in Konica lenses of this era. Inspect element condition and Hexanon coating. For modern adaptation, Konica AR adapters are commercially available.
