    ** For 1.4X and 2X, only EF 1.4X II / III and EF 2X II / III were tested.

    *** Sometimes non-Canon-made lenses may intentionally be recognized as a new one after lens firmware updates and cause the adapter failing to recognize them and losing PDAF. In that case, please send us a jpg file with all the EXIF data. We'll add new lens data to the adapter firmware to solve the issue.

    Lenses not tested, yet

    • Most of them are supported (CDAF only).
    • A few of them may have compatibility issues.

    Please wait for the next firmware update for better lens compatibility.
