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. 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.
