The PENTAX DCF SW binoculars are available in 8x25 and 10x25 models and offer high-resolution phase-coated and super-reflective coated roof prisms to provide high-resolution, high-contrast images. Waterproof and nitrogen filled (JIS Class 6), the DCF SW models allow submersion up to3 feet. The ultra-compact, dual-hinge design is exceptionally portable. Helicoid eyepiece rings with four click stops offer the most comfortable eye relief and the fully multi-coated lenses increase light transmission and color quality. The long eye relief allows for viewing with or without glasses and the click-stop adjustment locks in the right eyepiece diopter. The rubber-covered exterior provides a sure grip and protects the internal mechanisms. All PENTAX binoculars feature a Worry-Free Warranty.
