    Description

    The Pentax SP 8x40 Binoculars are designed for both astronomical and terrestrial use. They feature large, fully multi-coated 40mm objectives that reduce reflection and maximize light transmission through the entire optical path

    Designed for both astronomical and terrestrial use, Pentax's 8x40 / 10x50 /12x50 /16x50 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 10x 12x 16x magnification provides an immersive observation experience whether users are bird watching or comet hunting.

    The binocular sports a generous 13mm (8x40, 10x50, 12x50) 11mm (12x50) 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. 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.

              Jason P. ★★★★★

              The wide 65.6° field of view made scanning for birds feel effortless, and the focus wheel is buttery smooth. Took them out at dawn and the fully multicoated optics pulled in plenty of light even in dim conditions.

              Emily ★★★★★

              The rubberized armor gives a confident grip even with damp hands, and the large center focus wheel snaps into sharp clarity fast. I spent an hour watching warblers in the treeline without any arm fatigue, which surprised me for an 8x40.

              John X. ★★★★★

              The 65.6° wide field of view is what sold me, and it really does make scanning for warblers feel effortless. The center focus wheel turns smoothly even with gloves on, and the rubberized body has survived two rainy hikes without a slip. Genuinely sharp edge to edge for the price.
