Mark II of this lens sports a more svelte and lighter weight design for greater versatility and portability. Portrait-length prime is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides a 127.5mm equivalent focal length. Bright f/1.8 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over focus position when using shallow depth of field techniques. One extra-low dispersion element and four elements made from highly transparent glass contribute to reducing a variety of aberrations in order to produce well-corrected imagery with accurate color and no color fringing. One large-diameter aspherical element minimizes distortion and spherical aberrations in order to produce high sharpness and accurate rendering. HD Nano multi-layer coating has been applied to individual elements to reduce flare and ghosting for improved contrast. Also, this coating is water-resistant to help protect the exposed surfaces from moisture. STM autofocus motor delivers quiet and precise focusing performance along with a minimum focusing distance of 2.6′. Electronic contacts convey Exif data as well as permit camera-based aperture selection. Additionally, an integrated USB port permits updating the lens’s firmware. Rounded nine-blade diaphragm contributes to a pleasing bokeh quality. Included lens hood shades the front element from flare-causing stray light and also offers some additional physical protection.
