The M42 Screw-Mount Lens to MFT Mirrorless Camera Adapter with Macro from FotodioX is an all-metal adapter that allows you to connect a M42 screw-mount lens to a Micro Four Thirds body. It is designed for macro focusing, featuring an extendable helicoid that covers focus from infinity to close distances with variable magnification ability depending on the lens. For mounting, the adapter comes with chrome-plated brass mounts that help ensure a tight fit and connection.

Please note that this is a manual adapter, and so any electronic communication between the lens and the camera is disrupted. Any lens without a manual aperture control ring will stop down to its smallest f-stop by default. Manual exposure and metering are still possible with your camera's aperture priority mode.
