The KIPON Mamiya 645-S/E E 0.7x Adapter is an electronic adapter that can mount Mamiya 645 lenses onto Sony E mount camera bodies and control the aperture of the lens with the camera. The adapter offers infinity focus exclusively in manual mode.

The adapter is equipped with a contact and built-in circuit board with a chip, allowing the camera lens and body to interact electronically. With this adapter, you can control the lens aperture electronically with the adapter itself. The 0.7x optic adapter eliminates the crop factor and increases the aperture.
