Fast and wide, the XF 16mm f/1.4 R WR is a 24 mm-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. Both a Nano-GI coating and HT-EBC coating are also used to control ghosting and flare for enhanced contrast and color fidelity when working in strong lighting conditions. 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.
