Designed for nature enthusiasts and bird watchers, the Pentax 8x43 Z-Series ZD WP Binoculars feature multiple optical technologies to improve the image quality and ensure accurate colors in all weather and lighting conditions.The image-enhancement starts with hybrid aspherical lens elements that eliminate distortion around the edges of the lens for clear edge-to-edge views and corrects lens astigmatism that can prevent the ability to bring subjects into sharp focus. Anti-reflection fully multicoated optics maximize light transmission through the entire optical path to make views appear bright and crisp, especially in low light. Finally, the BAK4 roof prisms are phase-corrected to enhance contrast and further correct chromatic aberration. These technologies work together to produce bright and clear high-contrast images with accurate colors and virtually no distortion.Complementing the optical performance is a housing that is built for a lifetime of rugged outdoor use. The chassis is made of a lightweight and durable magnesium alloy with a rubberized armor that protects against impacts while providing a slip-resistant grip. The optical tubes are nitrogen filled for fogproof performance and O-ring sealed to make the binoculars submersible to as much as 3.3'. An protective external lens coating helps to repel dust, water, and oil to ensure obstruction-free viewing. For longer glassing sessions, they are tripod mountable with an optional adapter.Optical Performance 8x magnification43mm objective lensesBAK4 Roof prism optical pathAnti-reflection fully multicoated opticsPhase corrected prisms produce high-contrast images with true color renditionHybrid aspherical lens elements correct for spherical aberrations to reduce distortion at the edges of the lens and corrects for astigmatism that can prevent sharp focusing331' field of view at 1000 yards50 angle of viewUse and Handling Closed bridge configurationLarge knurled center focus wheelRight-eye diopter adjustment22mm eye relief, 5.4mm exit pupilTwist-up eyecups for use with or without eye wearTripod mountable with optional adapterConstruction Details Lightweight and durable magnesium alloy housingRubberized armoring protects against impacts and provides slip-resistant gripNitrogen-filled, fogproof and submersible to 3.3' (1m)Internal focusing system helps to maintain waterproof sealsDust/water/grease repellent coatings keeps the optical surfaces clean
