Pentax SP 8x40 Binocular

Pentax's;8x40 S-Series SP Binocular;boasts a wide 65.6° angle of view and porro prisms that produce a rich depth of view. 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. The coatings ensure bright and clear high-contrast images even in low-light, and its utilitarian 8x magnification brings subjects close while maintaining wide 430' field of view at 1000 yards to preserve situational awareness. The binocular sports a 13mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images. 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.
