Given the social distancing measures in place around the world right now, this seems like a good idea. Fujifilm Japan has filed a new patent for a couple of long telephoto prime lenses. Specifically, XF 300mm f/4 and 500mm f/5.6 lenses. Designed for Fujifilm’s line of APS-C cameras, these would offer the equivalent field of view to about 450mm and 750mm respectively on full-frame systems.
There is a fair amount of in-depth technical discussion in the patent, much of which is largely irrelevant for most of us unless you’re into that sort of thing, but it essentially boils down to two possible specifications of lenses.
Embodiment 1
- Focal length: 292.94mm
- Aperture: f/4.11 (f/4)
- Field of view: 5.6°
Embodiment 2
- Focal length: 486.99mm
- Aperture f/5.76 (f/5.6)
- Field of view: 5.0°
As with all patents, there are no clues when or if these lenses will actually come to market. But there isn’t exactly a massive selection of long telephoto Fuji lenses, with the longest currently being the XF 200mm f/2. So, maybe there’s some hope for Fuji shooters who want to cover more sports and wildlife in the future.
