Trusted in a wide range of weather and light conditions, the Pentax 8x40 S-Series SP WP Binocular is built for dependable outdoor viewing. Its 40mm objective lenses are fully multicoated to reduce reflection and maximise light transmission through the optical path, while still keeping the binoculars comfortable for long days on the trail. The traditional porro prism design delivers a rich sense of depth for a more immersive viewing experience, and the larger body provides a secure, easy-to-hold grip. With bright, clear, high-contrast images in low light and 8x magnification that brings distant subjects closer, the binocular also maintains a 363 field of view to help preserve situational awareness.

Designed for trail use as well as optical performance, the tubes are nitrogen-filled and O-ring sealed for fogproof reliability and submersible performance to as much as 3.3. The binocular also features a generous 20mm eye relief, while the fold-down eyecups help block stray peripheral light that can reduce image brightness.
