The Fotodiox Canon EF Pro Lens Adapter with Built-In Iris Control for Micro Four Thirds Cameras is a high quality adapter that allows you to mount a Canon EF mount lens to a Micro Four Thirds camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment. Additionally, this lens features iris control from f/1.7 to f/22.

This adapter will not allow for electronic control over lens functions. In order to function with automatic metering you will need to place the camera in manual or aperture priority mode, where the camera will utilize stop-down metering to determine the appropriate shutter speed.
