Bright FUJINON 23mm f/2 fixed focal length lens

Optimisation of the sensor for the 23mm f/2 lens fully exploits the advantage of a single focal length lens for superior edge-to-edge image quality.

23mm f/2 single focal length lens

Stunning image quality without compromise,  packed into a slim compact body... These were the highest objectives when the FUJIFILM X100S was being developed! And they have been achieved through the incorporation of a newly developed, non-interchangeable, non-collapsible, fixed focal length lens. While featuring the generous brightness of a maximum f/2 aperture, the large-diameter rear lens group is integrated into the body for an ultra-slim profile. In addition, the optimisation of the sensor for this special lens fully exploits the advantage of a fixed focal length lens for superior edge-to-edge image quality.

Optical design focussed on performance

The simple all-glass lens configuration (6 groups/8 elements) is designed around a single high-performance double-sided aspheric lens. Uncompromising image quality is assured by the application of multi-layer HTC-EBC(High Transmittance Electron Beam Coating) and other technologies. The result is perfectly balanced optical excellence promising low aberrations, sharp resolution and faithful colour reproduction.

Double sided aspherical lens

The use of an aspheric lens increases the freedom in lens design; however, it does not necessarily lead to the development of a good lens. For the FUJIFILM X100S, spherical lens elements are used as much as possible, and one double-sided aspheric lens made by a glass moulding process has been adopted as the most effective element for delivering maximum performance.

Super EBC coating for the highest quality images

All the lens elements used in the FUJIFILM X100S have been treated with multi-layer Super EBC (Electron Beam Coating), the same process used for Fujinon broadcasting video lenses and large-format camera lenses. By reducing ghosting and lens flare, EBC guarantees high image quality.

Capture superb "Bokeh" effects with the 9-blade aperture diaphragm

Providing a circular opening at the largest aperture, the 9-blade aperture diaphragm lets you capture pleasingly defocused background effects. Even with a slightly wide angle, the background is softly out of focus while the foreground is sharply defined.

Built-in ND filter

Equivalent to three stops, the built-in neutral density (ND) filter in the FUJIFILM X100S lens is ideal in situations where the light is very strong but you want to shoot at a slow shutter speed or a wide aperture.

The ND filter can be turned on or off quickly in the setup menu, or can be assigned to the Fn button for faster access.

10cm macro

The FUJIFILM X100S lets you get up close and personal with your subjects by allowing you to focus down to just 10cm

Wide Conversion Lens* - broadening the scope of the FUJIFILM X100S

Specifically designed to seamlessly unite with the look and feel of the X100S without impacting on its exceptional performance, the Wide Conversion Lens expands the angle of view from the original 35mm** to 28mm**. Its very light weight of 140g and compact design let you explore a wider range of expression without sacrificing the excellent portability of the X100S.
