This adapter allows you to mount Canon EF lenses to micro 4/3 cameras such as the Panasonic GH2 and AF100, as well as any other micro 4/3 mount cameras. The adapter gives you no EXIF data or aperture control. The aperture will be wide open unless set with a Canon DSLR body.
This adapter provides no electronic communication between the camera and lens. All focus adjustments must be made manually on the lens itself. There is no ability to change aperture, it will not be displayed on the camera, and it will not show up in the EXIF data.
- If you are measuring focus, this adapter will be off by about a foot. Most shooters with not be affected by this, but if you need this ability, you want the Canon EF Lens to Micro 4/3 w/aperture.
- This adapter will NOT work with the Canon 85mm f/1.2 or 50mm f/1.0 lenses since those are electronic focus. They will not focus when mounted to the adapter. Canon EF-S Lenses will not fit on it, but third party EF-S lenses work fine.
