Pentax's 10x50 S-Series SP Binocular features large oversized fully multicoated 50mm objectives to reduce reflection and maximize light transmission through the entire optical path. 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 large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities, and its high 10x magnification provides an immersive observation experience whether users are bird watching or comet hunting. 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).
