The FUJINON XF90mm F2 R LM WR is a fast-aperture prime lens with a focal length equivalent to 137mm; and a maximum aperture of F2.0, that delivers ultra-sharp images with rich bokeh even at the maximum aperture setting. The optical construction of 11 elements in 8 groups (including three ED glass elements) minimizes vignetting and creates beautiful bokeh thanks to the rounded diaphragm, which makes it perfect for portraiture as well as other applications. The optical construction comprises 11 elements in 8 groups, including three ED (extra low-dispersion) elements, which reduces chromatic aberrations to deliver sharp, rich images even at the widest aperture of F2.0. The rounded aperture blades combined with an optical construction designed to minimize vignetting creates beautiful circular bokeh right to the edge of the image. In addition, stunning depth is possible in images thanks to the differentiation between the subject and the bokeh in front and behind it. A linear motor is fast, quiet and accurate, but here four magnets are used for higher torque. The high-speed autofocus provides a more versatile shooting experience, allowing users to quickly react to subtle changes in a subjects facial expression. The lens features a weather- and dust-resistant structure with seven seals on the lens barrel. It can also work in temperatures as low as -10C. This keeps the lens protected from rain, dust and splashes of water when shooting outdoors. Model 16463668. Compatibility: Xf lens mount. Compatible with x-series cameras. 35mm focal length.
