Designed to provide an immersive experience for nature and bird watching, Pentax’s 8×40 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.
