| Adapter PM-EA |
| Summary | Main Characteristics | Notes - Related Units |
| The Adapter PM-EA allows the Exposure Meter EMM-7 to be used with the Auto Bellows, allowing accurate control of both exposure and color temperature. | Its tube accepts the photosensitive probe of the EMM-7. To use it, the camera is removed from the Auto Bellows and the PM-EA is mounted. |
The OM-2 does not require the EMM-7 because of its built-in automatic exposure control system. |
