Fujinon GF17-30mmF4, GF17-35mmF4 and GF17-35mmF4-5.6 Patents Spotted

Patents for the Fujinon GF 17-30mm f/4, Fujinon GF 17-35mm f/4 and Fujinon GF 17-35mm f/4.5.6 have now been spotted by the Japanese website asobinet.

We remind fellow FR-readers that 100% of the patents ever shared on FujiRumors in 11+ years of blogging never saw the light of the day.

Also, we now have the stunning Fujinon GF20-35mmF4, which kind of makes all these patented GF lenses redundant.
