Fujifilm XF23mm F1.4 R LM WR Lens

The Fujifilm XF23mm F1.4 R LM WR is a compact and lightweight, weather resistant, large aperture prime lens offering high resolution with fast and highly accurate autofocus. It is a full update of the current Fujifilm XF23mm F1.4 R, with a complete overhaul of optical performance including improved close-up focusing. This 23mm lens offers exceptional image sharpness, even when wide open at F1.4 and delivers fast and accurate autofocus in both stills and video.

Wide-angle focal length and broad shooting range
The XF23mm F1.4 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. Coupled with advanced close-up capability of , the lens accommodates a broad range of shooting situations.

Fast, silent, accurate AF
The lightweight design of XF23mm's focusing lens group means it is driven by a linear motor, resulting in silent, fast and highly-accurate AF. The AF is achieved with 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. The focus is attained in as fast as 0.04 seconds.
The lens maintains focus highly accurately even in the 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.

Compact, lightweight and weather-resistant construction
This lens weighs approximately 375g and measures 77.8mm long with the 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 at temperatures as low as -10℃. The focus ring has an improved control resolution for greater control, especially during manual focusing at a shallow depth of field. The gear pitch inside the focus ring is carefully designed for advanced movement detection capability, enabling linear focusing that responds precisely to the subtlest of fingertip movements.

Optical construction
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 wide open. The focusing group in the middle controls aspherical aberration and chromatic aberration. A two-element lens group including an aspherical lens at the far end reduces fluctuation of aberration caused by the movements of focusing elements, securing superior image quality across all focusing range from close-up to infinity.

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 indoors and nightscape. At F1.4, the lens provides a shallow depth-of-field to render background out-of-focus for bokeh, adding a clear contrast and three-dimensional definitions to sharply-focused the main subject on the focal plane. Comatic aberration is also well-controlled to capture small light sources as round points, avoiding color casts in the background in bokeh. The use of nine aperture blades ensures nearly round shape bokeh effect even around the maximum aperture.
