Know more about this product

The Olympus 8×40 Explorer S Binoculars feature a 60° wide-angle of view that offers an immersive viewing experience in the woods, at the stadium, or on your porch. Their traditional Porro prisms and anti-reflection coated optics maximize the light entering the 40mm objectives to produce bright and clear images with a rich depth of field. A knurled center focus wheel and an elastic polymer armored grip assist handling and give the viewer precise control of the optic, while fold-down eyecups provide comfortable use with or without eyewear.
