Designed to provide an immersive experience for nature and bird watching, Pentax's 8x40 S-Series SP Binoculars boast 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 their utilitarian 8x magnification brings subjects close while maintaining wide 430' field of view at 1000 yards to preserve situational awareness. The binoculars sport a 13mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images.Optical Performance8x magnification40mm objective lensesBAK4 porro prism optical pathAnti-reflection fully multicoated optics430.5' field of view at 1000 yards65.6° wide-angle of viewUse and HandlingClosed bridge configurationLarge knurled center focus wheelRight-eye diopter adjustment13mm eye relief, 5.0mm exit pupilFold-down rubber eyecups seal against ocular cavity and block stray peripheral lightConstruction DetailsInternal focusing systemRubberized armoring protects against impacts and provides slip-resistant gripTripod mountable with optional adapter
