The Fujinon XF50mm F1.0 R WR ultra fast lens with a portrait focal length of 50mm (equivalent to 76mm KB) has an exceptionally wide aperture to create a beautiful bokeh effect with velvety background blur. Despite its large diameter, the weatherproof lens is comparatively light and compact, making it an ideal choice for professional photographers and filmmakers. The autofocus focuses precisely and extremely quickly on the subject even at open aperture F1.0. The face and eye detection of the X series cameras ensures pinpoint automatic focusing despite the shallow depth of field. The focus ring for manual focusing can be rotated 120 degrees, allowing both precise control of the focus and shifting of the focal plane between close and infinity.
