The Olympus 8-16x40 Explorer S Zoom Binoculars feature a powerful zoom capability that offers an immersive viewing experience. You can scan the terrain for objects of interest on low power and dial up the magnification to make detailed observations and identification at long ranges.

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.

Optical Performance
