Chromatic Aberration Reduction
The combination of fluorite ED (extra low dispersion)  and super ED lens elements minimizes color fringing and delivers clear, crisp images.

High Dynamic Range

Natural bokeh achieved with nine iris blades

By adopting nine iris blades, FUJINON 4K lenses achieve a nearly circular aperture. This makes it possible to render images taking full advantage of a softer, more natural bokeh.
