      *** 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
