A couple of new lens patents have now been spotted by the Japanese website asobinet.
51mmF1.4
54mmF1.4
56mmF1.2
74mmF1.4
Interestingly the lenses seem to be designed for Full Frame rather than APS-C or GFX.
It’s not the first time that a full frame lens patents surfaced. We already spotted the 40mmF2.
