This is one of the smallest and lightest 10x40s currently on the market. One of the elements of the objective lenses is made of “Prominar XD” low dispersion  glass (Kowa sometimes calls this “Fluorite” glass), which is also used in Kowa’s top line of instruments (Genesis binoculars, Highlander BT, spotting scopes) and is supposed to minimize the inherent chromatic aberration (CA). Due to the very short build of the binocular, which generally can lead to more pronounced aberrations, the goal of reducing CA is only partially achieved, but overall, the image is clear, bright and shows quite good contrast. The transmission ratio of the central focusing mechanism is faster than many other 10x40s.
