Description — Mamiya 80mm f/4
The Mamiya 645 80mm f/4 Sekor Macro C N is a prime lens designed for the Mamiya 645 camera system, built around a medium format lens standard. With a fixed 80mm focal length sitting in the standard focal length range, it provides a natural, undistorted perspective well suited to close-up and detail work. The lens has a maximum aperture of f/4 and is classified as a macro type, making it a dedicated tool for photographers focused on precision close-up imaging.
Focusing is entirely manual, giving the photographer full control over focus placement — particularly valuable in macro photography where depth of field is extremely shallow and precise focus placement is critical. The 67mm filter thread provides broad compatibility with standard filter accessories. Weighing in at 600g, the lens has a solid, confident feel.
There is no image stabilization, so use with a stable support system is advisable. Compatible solely with the Mamiya 645 mount, this lens integrates seamlessly into that ecosystem for photographers already working within the Mamiya 645 system.
