We found a newly published Panasonic lens design patent which shows a 27mm f/1.8 lens designed for a fixed lens mirrorless camera with Four Thirds sensor. The patent also shows some possible variations of the lens design (24mm f/1.8, 25mm f/2.8 and 21mm f/2.8).
I am yet not sure Panasonic will ever launch a LX100 version with that lens.
