Mamiya 645 MF to Nikon F Adapter

This adapter connects Mamiya 645 manual focus lenses to Nikon F-mount cameras. It enables infinity focus and manual aperture control for digital or film photography. The all-metal construction uses chrome-plated brass mounts for a secure fit. Professionals can mix vintage glass with modern DSLR or SLR bodies.

Mechanical-Only Mount with No Electronics

The adapter contains no electronic contacts so autofocus, AE metering and image stabilization are disabled. Infinity focus is allowed by design though some lenses may not reach the infinity mark. Camera must be set to Manual or Aperture Priority mode for metering. Precise machining ensures zero play or wiggle once the lens is mounted.

Suits Photographers Using Manual Focus Mamiya 645

Ideal for shooters who want to adapt legacy Mamiya 645 manual focus lenses to Nikon F bodies. Not compatible with Mamiya 645AF or Phase One XF mount lenses. Buyers needing electronic aperture control or autofocus should look elsewhere. Works with a wide range of Nikon DSLR models from D40 through D800E and film SLRs.

Questions about this item

How does the 645 format lens perform when adapted to a Nikon F-mount body?

The adapter enables infinity focus with Mamiya 645 manual focus lenses on listed Nikon F cameras such as the D800, D700 and D4 series. Electronic functions including autofocus and metering are not transmitted, so the camera must be used in Manual or Aperture Priority mode.

What mount standard does the adapter use and what functions does it support?

It converts Mamiya 645 manual focus mount to Nikon F-mount. The connection is purely mechanical; aperture control stays on the lens and no EXIF data or autofocus signals pass through the adapter.

What physical clearance does the adapter need on the camera side?

The all-metal construction with chrome-plated brass mounts fits the standard Nikon F flange distance, so it mounts directly on any compatible F-mount body listed without extra spacers or modifications.
