Fujinon XF 16mm F1.4 R WR

 The XF 16mm f/1.4 R WR is a 24mm-equivalent wide-angle lens designed specifically for FUJIFILM X-mount mirrorless cameras. Two aspherical and two extra-low dispersion elements are featured in the optical design and help to reduce spherical and chromatic aberrations for improved sharpness, clarity, and color accuracy. Complementing the optics is a floating focus system that benefits autofocus speed and also maintains consistent performance throughout the focusing range. Additionally, the lens body is also weather-sealed to support working in trying environmental conditions. Notably fast f/1.4 maximum aperture affords increased control over depth of field and greatly benefits working in low-light conditions. Two aspherical elements control distortion, the curvature of the field, and spherical aberrations, which help to improve sharpness and realize more accurate rendering.HT-EBC coating has also been applied to the entire surface of each element to reduce lens flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. The weather-resistant design includes nine different seals in eight areas to prevent dust and moisture from entering the lens and to enable worry-free use in inclement conditions and freezing temperatures as low as 14°F.
