I'm hoping it is OK to post 1.2s NOT shot on a Df. I have a Sony A7RII (horrors!) that allows me to shoot a few different 1.2s that do not fit on a Nikon DSLR First two with a Cosina 55mm f1.2 in Pentax PK mount (not the Porst version--probably Tominon). Second two late Nikon 55mm f1.2. Third two Nikkor CRT 55mm f1.2. Fourth two Canon LTM 50mm f1.2. Last two, just for fun, Elgeet STL Navitar (Space Technology Laboratories) 86mm f1.2...anyway, it's a 1.2...
