Fujinon XF56mm f/1.7 Patent Spotted (plus XF18mmF1.4 with Slightly Different Optical System)
In 11+ years of sharing patents on FujiRumors, I have NEVER seen a single patent being shared that later on materialized into a real product.
This is why I warn you again: the patents you’ll read about today will remain on paper forever.
- Fujinon XF18mm f/1.4 with slightly different optical system than the one we already have on the market
- Fujinon XF56mm f/1.7
And no, the lens you see in the image above is not from the patent, but from a wildlife lens survey/article we shared in the past, were a reader made a mock-up of the lens.
