Pentax 8x43 Z-Series ZD WP Binoculars

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 conditionsThe 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 distortionComplementing 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 33' 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
