Fujinon GF28-100mm F4 and XF18-120mm F4 Patents Found

Two more patents have been spotted by asobinet.

One is the patent for the already release Fujinon XF18-120mm f/4 LM PZ WR and the other is for a Fujinon GF28-100mm f/4.

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.

The only patents that were accurate were the ones spotted after something has already been released.
