Overview
Pentax's 8x40 S-Series SP WP Binocular can be used with confidence in all weather and lighting conditions. The 40mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path without making them overly cumbersome for a long day on the trail. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The coatings ensure bright and clear high-contrast images even in low-light, and its utilitarian 8x magnification brings subjects close while maintaining 363 field 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.
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).
