Fujinon XF7mm F4, XF8mm F3.5, XF9mm F2.8 and XF10mm F2.8 Patents Found
Back at the X Summit in May, Fujifilm announced the Fujinon XF 8mm f/3.5.
FujiRumors already compared the XF8mmF3.5 in size to other Fujinon lenses here.
It is no surprise that during the development for this lens Fujifilm made several versions of it, and those versions now appeared as patents.
- XF7mm F4
- XF8mm F3.5
- XF9mm F2.8
- XF10mm F2.8
Looks like Fujifilm went for the golden middle: not the widest nor the longest, not the slowest nor the fastest: hence, XF 8mmF3.5. A good decision if you ask me, but you are free to tell us your opinion in the comments.
