The FUJIFILM XF 50mm f/1.0 R WR; is a portrait-length prime lens featuring an impressive and unique f/1.0 maximum aperture. A Super EBC coating also suppresses flare and ghosting for greater contrast when working in bright and backlit conditions. Additionally, complementing the optics is a fast-performing DC autofocus motor and a robust physical design that is weather-sealed to suit working in trying environmental conditions. Exceptionally bright f/1.0 maximum aperture excels in difficult lighting conditions and also provides impressive control over depth of field for isolating subject matter using selective focus techniques. Two extra-low dispersion elements reduce color fringing and chromatic aberrations in order to provide greater clarity and color accuracy.DC autofocus motor is well-suited to move large elements and helps to realize quick, accurate, and smooth focusing performance. The weather-resistant design incorporates 11 distinct seals that prevent dust and moisture from entering the lens and enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.
