Ricoh Imaging | Pentax SD 8 x 42 WP Binoculars
Pentax designed the 8x42 S-Series SD WP Binocular 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 even in low-light. Its general purpose 8x magnification brings subjects close while maintaining a wide 60° angle of view to preserve situational awareness.


Exceptional quality meets high-end expectations.

Large objective lenses incorporated in the design allow for contrast-rich, bright viewing under all light conditions.

Premium multi-layer coatings assure the maximum light transmission through the binocular. The result is bright, crisp, true-to-life images in the widest range of viewing conditions.

Specialized protective coating (SD models only) repels dust, water and grease to keep your optics clean and your image quality at its peak.

Rigid body construction makes these binoculars extremely rugged to maintain optical alignment. This ensures comfortable viewing throughout the life of the product.

Waterproof and nitrogen-filled (JIS Class 6) to handle the most extreme weather conditions (submersible to 1m).
