Description — Mamiya 645 80mm f/2.8 N
The Mamiya Sekor C 645 80mm f/2.8 N is a prime lens built for the Mamiya 645 camera system, operating in the medium format space. With a maximum aperture of f/2.8 and a focal length of 80mm, it covers the standard focal length range and offers a useful degree of light-gathering performance. The lens is manual focus only, putting full control of focus in the photographer's hands — a workflow that pairs naturally with methodical studio and controlled-environment shooting.
Weighing in at 310g, it is a practical option for a medium format prime, avoiding the bulk that some longer or faster lenses in this format carry. The 58mm filter thread opens up a broad range of compatible filter accessories. There is no image stabilization, so technique and support equipment become important factors when shooting at lower shutter speeds.
With its native Mamiya 645 mount, this lens fits directly onto compatible bodies without adapters or compromises.
