Description — Mamiya Macro MF 120mm f/4
The Mamiya M645 Macro 120mm f/4 is a prime lens purpose-built for close-up photography within the Mamiya 645 mount system. Operating at a fixed 120mm focal length and a maximum aperture of f/4, it is classified in the standard focal length range for medium format use. Focusing is entirely manual, which suits the deliberate, controlled workflow that macro photography demands.
The lens features a 67mm filter thread, providing compatibility with a wide variety of photographic filters. At 620g, it carries the substantial build quality expected of medium format optics. There is no image stabilization on this lens, so photographers working at close distances will benefit from using a tripod or rigid support system.
