【for Fujifilm X-mount】Prime wide-angle lens is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides a 35mm equivalent focal length. Due to its physical design, this lens is not suitable for use on the FUJIFILM X-Pro3 camera and may scratch the camera body if attached. | 【Auto Focus】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. | 【Large Aperture】Bright f/1.4 maximum aperture suits working in low-light conditions and also affords greater control over depth of field. | 【HD Nano】Two extra-low dispersion elements reduce color fringing and chromatic aberrations in order to achieve a high degree of clarity and color accuracy. Two high refractive index elements help to control spherical aberrations and reduce distortion in order to realize high sharpness and accurate rendering. | 【Compact and durable】 Integrated manual aperture ring for tactile exposure control; this ring also features an 'A' position for automated, camera-based aperture selection. Integrated micro-USB port can be used to update the lens's firmware.
