The FUJINON XF90mmF2 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.
