Description — Minolta 90mm f/4
The Minolta 90mm f/4 M-Rokkor is a prime telephoto lens designed specifically for the Leica M mount rangefinder system. With a fixed 90mm focal length and full-frame coverage, it delivers a consistent telephoto perspective suitable for portraiture, travel, and detail-focused work. The f/4 maximum aperture keeps the optical design compact, contributing to the lens's impressively low weight of just 250g — a meaningful advantage when shooting handheld or traveling light.
Focusing is entirely manual, in keeping with the deliberate, precise nature of rangefinder photography. There is no image stabilization, so technique matters. The 40.5mm filter thread is petite, keeping compatible filter accessories affordable and easy to carry.
Whether used on a classic film M-mount body or a modern digital rangefinder, this lens offers a straightforward, no-frills telephoto option in the M-mount ecosystem.
