Mamiya 120mm f/4 Sekor D Macro Manual Focus Lens for Mamiya 645AF, Phase One Body Review

The Mamiya 120mm f/4 Sekor D Macro is a manual-focus medium format macro lens designed for Mamiya 645AF cameras and Phase One digital backs. As a legacy optic, it occupies a niche spot in the medium format ecosystem, offering dedicated macro capabilities in the 120mm focal length with a 67mm filter thread. This lens is typically found on the used market, where condition varies from good to excellent.

For photographers already invested in the Mamiya 645AF system or Phase One digital backs who need macro work, this lens delivers the focal length and magnification required for close-up product, botanical, or technical photography in medium format. At 482 dollars, it represents an affordable entry point for medium format macro compared to newer AF alternatives, though manual focus demands patience and skill, especially at macro distances where depth of field is razor-thin.
