Also the Leica 45mm f/2.8 lens has been designed by Konica-Minolta?

Egami spotted that Konica Minolta patent. So it’s not Leica, but Konica that likely designed the Elmarit 45mm f/2.8 MFT lens? Wondering what kind of role had Leica on that lens development…or are they only selling the Leica logo?

Note: There are differences in the design between that Konica patent and the real Leica lens. That said it is not unusual for a patent to show different kind of design variations. So we astill don’t know if it’s Konica or not that designed the Leica 45mm lens.
