Description The entire housing is made of magnesium. Thanks to ED lenses, multi-coatings and matched optics, they offer a wide field of view, high edge-to-edge sharpness and transmission values, as well as a shorter close focus. Their robustness and optical performance make them unique performers in their class. You will not find a comparably equipped binocular in this price range.
