Pentax designed the 10x42 S-Series SD WP Binoculars for a lifetime of rugged outdoor use in all weather and lighting conditions. The 42mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path. Its roof prisms are phase-corrected to correct for chromatic aberrations, ensuring bright and clear high-contrast images with true color rendition in even low light. Its 10x magnification, 60° angle of view, and 315' field of view at 1000 yards provides an immersive observation experience.

Complementing the optical performance are construction details made for the trail. The optical tubes are nitrogen-filled and O-ring sealed for fogproof performance and to make them submersible to as deep as 3.3'. The binoculars sport a generous 18mm eye relief, and twist-up eyecups ensure comfortable viewing with or without eye wear. Protective coatings on the exterior lens surfaces repel water, dirt, and oil to keep them clean for unobstructed viewing.
