• Ultra-wide prime lens designed for Fujifilm APS-C-format X-mount mirrorless cameras where it provides a 20mm equivalent to full-frame 35mm focal length. Bright f/1.4 maximum aperture suits working in difficult lighting conditions and helps to maintain a relatively compact form factor. 14 lens elements in 11 groups provide a sophisticated optical design. Two aspherical lens elements are optimized for distortion and off-axis optical aberration allowing the lens to maintain excellent resolution throughout the entire focusing range. HD Nano multi-layer coating has been applied to individual elements to reduce flare and ghosting for improved contrast.Four ED (extra-low dispersion) lens elements greatly reduce color fringing and chromatic aberrations to produce greater clarity and color accuracy no matter which aperture you choose. The lens adopts steady, fast and smooth AUTO FOCUS,STM autofocus motor delivers quiet and precise focusing performance along with a minimum object distance of just 8.7",and support EXIF and an integrated USB port permits updating the lens's firmware.
