A new Konica-Minolta lens patent describes the construction of a new 50mm f/1.4 lens design for the Micro Four Thirds system. It is well-known that Konica designed some of Panasonic MFT lenses. So it is likely that this design will become a real product branded as Panasonic or Leica.
Konica designed the following “Panasonic” lenses:
Leica 45mm f/2.8 (patent here)
Leica 8-18mm f/2.8 (patent here)
Panasonic 150mm lens (patent here).
