Fuji 23mm f1.4 lens | Buy FUJI 23mm f1.4

The XF23mmF1.4 is a next-generation prime lens, designed with an eye toward supporting future camera sensors with even higher resolution and setting the new benchmark for XF lenses for the highest level of image resolution capability. With a highly versatile wide focal length of 23mm (equivalent to 35mm in the 35mm film format), the lens boasts uncompromising optical performance to deliver incredible sharpness even when wide open at F1.4. It controls camera movement and digital noise in low-light conditions, giving users flexibility on when to shoot. Its shallow depth of field makes the background out of focus for creamy bokeh, adding three-dimensional definitions to the main subject. The use of nine aperture blades ensures an almost round-shaped bokeh effect even around the maximum aperture.

 Along with advanced close-up capability, the lens adapts to a wide range of shooting situations.

The new XF23mmF1.4 features fast, high-precision AF in a compact, lightweight and rugged construction to take advantage of completely overhauled optical performance in stills, video and all shooting situations. The use of a linear motor means that the AF system is silently operated to achieve high-precision focusing in as little as 0.04 seconds, capturing a decisive photographic opportunity in all conditions. *1 The lens is easy to handle despite being a large aperture lens, weighing approximately 375g and measuring 77.8mm long with a filter thread size of 58mm. The additional reinforced design that offers dust and moisture-resistant construction and the ability to operate in temperatures as low as -10°C, provides the characteristic mobility of the X system while delivering the advanced optical performance expected of large-aperture lenses, in all shooting conditions. The XF23mmF1.4 rewrites the existing benchmark to drive the evolution of the X-Series over the next decade and beyond.

2.Product Features

(1) Next-gen resolution performance with edge-to-edge sharpness when fully open in F1.4

・ The lens consists of 15 lens elements, including two aspherical elements and three ED elements, in 10 groups to effectively minimize chromatic aberration and spherical aberration, delivering edge-to-edge sharpness even when fully open. The focus group in the middle controls aspherical aberration and chromatic aberration. A two-element lens group that includes an aspherical lens at the far end reduces aberration fluctuation caused by movements of the focus elements, ensuring superior image quality throughout the focus range from foreground to infinity.

・ With a maximum aperture of F1.4, the lens allows users to produce high-quality images with minimal camera shake and digital noise, even in low-light conditions, such as dimly lit interiors and nightscapes. At F1.4, the lens provides a shallow depth of field to render the background blurred for creamy bokeh, adding clear contrast and three-dimensional definitions to sharply focus on the main subject in the focal plane. The comic aberration is also well controlled to capture small light sources such as round dots, avoiding color hues in the bokeh background. The use of nine aperture blades ensures an almost round-shaped bokeh effect even around the maximum aperture.

 (2) Popular wide-angle focal length and wide shooting range

The XF23mmF1.4 offers a popular and highly versatile focal length of 23mm (equivalent to 35mm in the 35mm film format) with a minimum working distance of 19cm and a maximum magnification of 0.2x. The close-up capability, a huge improvement over the previous model, allows for a dynamic framing feature of wide-angle lenses, capturing the main subject in the foreground while providing greater dispersion of the background in the frame. Users enjoy greater flexibility as they do not need to worry about the distance from the main subject.

(3) Quiet, fast and high-precision AF

• The lightweight design of the XF23mmF1.4's focus lens cluster means it's driven by a linear motor, resulting in quiet, fast and high-precision AF. AF is achieved with the Inner Focus system, which keeps the range of motion small for the focus lens group while improving the level of accuracy in controlling the amount of focus required within the range. Focusing is achieved in as little as 0.04 seconds, ensuring that users don't miss a decisive photo opportunity. * 1

• The lens maintains focus with great precision even in AF-C mode, and is also optically designed to reduce changes in angle of view, caused by focus breathing, to approximately 0.011%, making it an ideal choice for video recording.

• The mechanism that drives the six-element focus group together reduces the fluctuation of the aberration caused

• The mechanism that drives the focus group of six elements together reduces the fluctuation of aberration caused by focusing, producing clear and sharp images in all focus positions, from foreground to infinity.

(4) Advanced mobility based on compact, lightweight and weatherproof construction

• The XF23mmF1.4 is compact and lightweight, weighing approximately 375g and measuring 77.8mm long with a filter thread size of 58mm. The outer diameter of the focus lens group is kept small to accommodate a linear motor in the space created to achieve a slim design.

• The lens body is weather-sealed in 11 locations to make it dust and weather resistant and can be used in temperatures as low as -10°C, accommodating snapshots in the rain, astrophotography on cold winter nights, and changes in external conditions seamlessly.

• The focus ring has an improved control resolution for greater control, especially during manual focus at shallow depth of field. The gear pitch within the focus ring is carefully designed for advanced motion detection capability, allowing for linear focusing that responds precisely to the subtlest movements of the fingertips.

• Position A (auto) lock offers reliable operation, locking the aperture ring in place to prevent any unintentional adjustments during filming.

• The shape of the flute on the focus ring is carefully designed to make it easy to remove dirt stuck in the grooves.
