Fujifilm XF23mm f/1.4 R LM WR Lens

The Fujifilm XF23mm f/1.4 R LM WR Lens is a wide angle prime lens from Fujifilm for Fujifilm X mount, suited to landscape. It has a 58mm filter thread, an aperture of f/1.4 and weighs 375g.

The XF23mm F1.4 WR is a new-generation prime lens, designed with a view to supporting future camera sensors of even greater resolution and setting a new benchmark for XF lenses.

Focal Length and Bokeh

With the highly versatile wide-angle focal length of 23mm (equivalent to 35mm in the 35mm film format), the lens boasts uncompromising optical performance to deliver incredible sharpness, giving users wide shooting flexibility.

Its shallow depth of field renders the background out-of-focus for creamy bokeh, adding three-dimensional definitions to the main subject.

The use of nine aperture blades ensures a nearly round shape bokeh effect even at maximum aperture. The use of a linear motor means the AF system is driven silently to attain a highly accurate focus in as fast as 0.04 seconds. This large-aperture prime lens is easy to handle, weighing approximately 375g and measuring 77.8mm long with a filter thread size of 58mm.

The dust- and moisture-resistant construction has the capability to operate at temperatures as low as -10°C while providing outstanding optical performance.

New-generation resolution performance with edge-to-edge sharpness when wide open at F1.4

The lens consists of 15 lens elements, including two aspherical elements and three ED elements, in 10 groups to effectively minimise chromatic and spherical aberration, delivering edge-to-edge sharpness even when wide open. The middle focusing group controls aspherical and chromatic aberration.

A two-element lens group including an aspherical lens at the far end reduces the fluctuation of aberration caused by the movement of focusing elements, securing superior image quality across the entire focus range.

Boasting the maximum aperture of F1.4, the lens allows users to produce high-quality pictures with minimal camera shake and digital noise even in low light conditions such as poorly-lit interiors and nightscapes.

At F1.4, the lens provides a shallow depth-of-field to render background out-of-focus for creamy bokeh, adding a clear contrast and three-dimensional definition to sharply-focused the main subject matter.

Chromatic aberration is also well-controlled to capture small light sources as round points, avoiding colour casts in the background bokeh. The use of nine aperture blades ensures a nearly round shape bokeh even at the maximum aperture.

b>Popular wide-angle focal length and broad shooting range

The XF23mmF1.4 offers a popular and highly versatile focal length of 23mm (equivalent to 35mm in the 35mm film format) with the minimal working distance of 19cm and the maximum magnification of 0.2x.

The close-up capability is a huge improvement over the previous model, allowing users to enjoy greater flexibility.

Silent, fast and highly-accurate AF

The lightweight design of XF23mmF1.4’s focusing lens group means it is driven by a linear motor, resulting in silent, fast and highly accurate autofocus. AF is achieved by the Inner Focus system, which keeps the range of movements for the focusing lens group small while improving the level of precision in controlling the amount of focusing required within the range.

Focus is attained in as fast as 0.04 seconds, ensuring that users do not miss a decisive photo opportunity”.

The lens maintains focus accurately even in the AF-C mode and is also optically designed to reduce changes in the 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 focusing group together reduces the fluctuation of aberration, producing clear and crisp images at all focus positions.

Advanced mobility based on compact, lightweight and weather-resistant construction

The XF23mm F1.4 is compact and lightweight, weighing approximately 375g and measuring 77.8mm long with a filter thread size of 58mm.

The external diameter of the focusing lens group is kept small to accommodate a linear motor in the space created to achieve a slimline design. The lens barrel is weather-sealed at 11 locations so that it is dust and weather resistant and can be used in temperatures as low as -10℃, accommodating snapshots in rain or astrophotography during cold winter nights for reliable performance in all shooting conditions.

The focus ring has improved control resolution ideal for manual focusing at a shallow depth of field.

The gear pitch inside the focus ring is carefully designed for advanced movement detection, enabling linear focusing that responds precisely to the subtlest of fingertip movements. The A (auto) Position Lock offers reliable operation, locking the aperture ring in place to avoid any unintentional adjustment during shooting. The shape of knurling on the focus ring is carefully designed to make it easy to remove dirt stuck in grooves.
