Designed for both astronomical and terrestrial use, Pentax's 12x50 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 12x magnification provides an immersive observation experience whether users are bird watching or comet hunting.

The binocular sports a generous 11mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images. Its over-sized objectives add weight and bias the center of gravity forward making user fatigue a concern and hand-shake a possibility, so to aid long observation sessions the binocular can be mounted on a tripod using an optional adapter.

Designed to provide an immersive experience for nature and bird watching, 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.
