Mamiya ZE to Micro Four Thirds adapter

This brass and stainless steel adapter lets you mount Mamiya ZE lenses on Micro Four Thirds mirrorless cameras such as Olympus PEN and Panasonic Lumix models. An integrated aperture control dial provides manual stop-down control for exposure and depth of field. Infinity focus is maintained across the focal range and leaf springs eliminate play between lens and mount. Electronic communication is not supported so autofocus and automatic diaphragm functions will not operate.

Thermals noise and power

As a purely mechanical mount adapter there are no electronic components that generate heat or draw power from the camera. Operation is completely silent with no fans motors or active cooling involved. The all metal construction adds negligible weight and does not affect the camera battery life or thermal performance in any way.

Build integration and workflow

The adapter fits directly between a Mamiya ZE lens and a Micro Four Thirds camera body requiring no additional tools or accessories. It frees you from purchasing native lenses by unlocking your existing manual focus glass for use on a modern mirrorless system. You will need to work in stop down metering mode and focus manually since the adapter does not transmit aperture data or autofocus signals to the camera.

Questions about this item

How do I attach the Mamiya ZE lens to my Micro Four Thirds body using this brass adapter?

Align the lens mount dots, twist the adapter onto the lens until the leaf springs click, then mount the combined unit to the camera bayonet; the stainless steel finish prevents binding during the final lock.

Will the integrated aperture control dial need lubrication or replacement after extended use?

The all-metal dial runs on a dry brass-on-brass interface; no lubrication is required and the component is not user-serviceable, so it remains maintenance-free for the adapter's life.

What stops me from focusing to infinity when using Mamiya ZE glass on this adapter?

Nothing — the precision-machined brass flange guarantees infinity focus across the full focal range, so the hard stop is the lens's own infinity mark, not the adapter.
