The Pentax’s 8×40 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.
Fully-multi-coated optics assure maximum light transmission resulting in high quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view. Aluminum-diecast body adds strength and durability. View your subjects even in dim light with high-quality BaK4 prisms that transmit more light at the edges to enhance illumination.
