Fotodiox Pro Lens Mount Adapter Mamiya 645 AF/AF-D to Nikon Z camera accessory

Lens Mount Adapter Mamiya 645 to Nikon Z

This adapter connects Mamiya 645 AF and AF-D lenses to Nikon Z-Mount mirrorless camera bodies. It provides a secure, light-tight fit that supports infinity focus and manual aperture control. The built-in de-clicked iris allows variable aperture adjustment even when the lens electronics are inactive. Durable construction handles the weight of larger medium-format optics.

Photographers with existing Mamiya 645 glass

Shooters who own Mamiya 645 AF or AF-D lenses can use them on a Nikon Z system without buying new glass. The adapter adds minimal bulk at 3 x 3.3 x 2 inches and 0.5 lbs. Buyers who need autofocus or electronic aperture communication should look elsewhere, as the connection is fully mechanical. Videographers requiring smooth, click-less iris control will appreciate the built-in iris ring.

Mechanical flange-distance correction

The adapter bridges the flange-distance difference between the Mamiya 645 system and the Nikon Z mount, enabling infinity focus. No optical elements are included, so image quality depends entirely on the adapted lens. The de-clicked iris ring provides stepless aperture control for exposure adjustments during recording. Compatibility is limited to Mamiya 645 AF and AF-D lenses; other Mamiya mounts are not supported.
