The Olympus 10x50Explorer S Binoculars feature high magnification and wide objectives that offer an immersive viewing experience in all light conditions from pre-dawn through late dusk. Their traditional Porro prisms present you with a rich depth of field that allow you to more easily discern the distances between objects in your view for a real "3D" experience. Anti-reflection coated optics maximize the light entering the objectives to produce bright and clear images with accurate colors and crisp resolution. A knurled center focus wheel and an elastic polymer armored grip assist handling and give you precise control of the optic, while fold-down eyecups provide comfortable use with or without eyewear.
