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.

Questions about this item

Does the adapter add any electrical load or heat to the camera body during extended shooting?

No, the adapter is purely mechanical with no electronics, so it draws no power and generates no heat during all-day use.

What must my Mamiya 645 AF/AF-D lens already have for this adapter to control aperture?

The adapter includes a built-in de-clicked iris ring, so it works even if the lens's electronic aperture is non-functional; no lens-side aperture ring is required.

Will infinity focus be accurate when I pair this adapter with older manual-focus Mamiya 645 lenses?

The adapter is designed for AF/AF-D lenses and guarantees infinity focus with that mount; compatibility with purely manual-focus M645 lenses is not confirmed.
