Prime portrait-length lens is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides an 85mm equivalent focal length. Bright f/1.4 maximum aperture suits working in low-light conditions and also affords greater control over depth of field. One extra-low dispersion element reduces color fringing and chromatic aberrations in order to achieve a high degree of clarity and color accuracy. One high refractive index element helps to control spherical aberrations and reduce distortion in order to realize high sharpness and accurate rendering. STM stepping motor enables quick, quiet, and precise autofocus performance along with full-time manual focus override. Additionally, an internal focusing design maintains the overall lens length during use for improved handling and quicker response. Integrated manual aperture ring for tactile exposure control; this ring also features an 'A' position for automated, camera-based aperture selection. Nine-blade diaphragm contributes to a pleasing bokeh quality. Integrated micro-USB port can be used to update the lens's firmware.
