The National Geographic 8x25 is a compact, lightweight binocular that fits easily into a backpack, glove box or handbag, for travel, hiking, game drives and sports events. It gives 8x magnification with 25 mm objective lenses, a good size for daytime viewing. Like the rest of the National Geographic compact range it has coated optics, a central focus wheel and a diopter adjustment. We could not find the maker's full specifications for this exact model (field of view, weight, prism type), so please check the packaging for these details.
