The Porro prism binoculars of the S series feature an objective lens diameter greater than 40 mm and are the continuation of the A series. With the same high-quality coatings as the A series, impeccable image quality is guaranteed. Characteristic of this series is the high light intensity due to the large objective lens diameter. The S series offers many of the features found in more expensive binoculars. They are robust with a full rubber housing, including an extra-large central focusing wheel. They provide exceptional optical performance with high-quality BaK4 prisms. All lenses are fully multi-coated, featuring an aluminum die-cast housing, Enhanced Light Transmission coating, complete rubber armoring, a large central focusing wheel, and a click-stop diopter adjustment.
