Fold-Down Rubber EyecupsOVERVIEW

Designed for nature and bird watching, the Pentax's 8x40 SP Binocular is your binocular of choice. It 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.
