A manual-focus telephoto lens for 35mm SLR cameras with Konica AR mount, offered in f/2.5 and f/3.5 versions

Overview

The Konica 135mm is a telephoto lens designed for 35mm SLR cameras using the Konica AR mount. Two primary versions are documented: the Hexanon AR 135mm f/2.5, announced in 1973, and the 135mm f/3.5 (late), introduced in 1978 and produced until 1987. The f/3.5 late version is distinguished by its rubber focus grip and minimum aperture of f/22, suggesting a design update from earlier iterations. The f/2.5 version traces its lineage to a 1961 F-mount lens, later adapted to the AR mount in 1965.

Design

The Konica 135mm f/3.5 (late) features a rubber focus grip and is noted for its compact size and lightweight build. The f/2.5 version includes a focusing ring for manual operation and shares the same AR mount compatibility. Both versions are built for durability and smooth handling on Konica SLR bodies.

Context

The f/2.5 version was positioned as a faster alternative to slower 135mm offerings like the f/3.2 and f/3.5, making it more suitable for low-light use. It remained in production through the 1970s and 1980s, outlasting earlier compact 135/3.5 models discontinued by 1970. The f/3.5 late version, introduced in 1978, reflects a refined iteration within Konica’s telephoto lineup.

Market

The Konica 135mm f/2.5 has appeared in the used market at prices ranging from $74 to €129, with one listing at $120 OBO. At under $100, it has been described as a "steal" by forum users, reflecting its value among vintage lens collectors. No common failures or maintenance issues are reported.
