Panasonic stated multiple times they will not make APS-C L-mount lenses. But yet here we are with a brand new Panasonic patent disclosing the 18mm f/4.0 APS-C lens. I am uncertain if this lens will have L-mount or still be for MFT.
I don’t see Panasonic making APS-C lenses any time soon. They focus now will be on making new FF lenses as fast as they can.
