Each element has been covered with anti-reflective coatings, which are supposed to significantly minimize light reflection and the appearance of light leaks and flares. It is also supposed to improve overall contrast of photographs in demanding conditions. The lens is equipped with a 8-blade aperture which can be regulated within the range of f/2.8-f/16. The focal length of 25mm ensures 10.3-grade field of view. The lens is, of course, manual.
