Pentax - 8x43 Z-Series ZD ED Binoculars

The B&H Binocular Buying Guide

With an eye for the discerning nature enthusiast, the Pentax 8x43 Z-Series ZD ED Binoculars features 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 and extra-low dispersion (ED) glass. The aspherical elements eliminate distortion around the edges of the lenses for clear edge-to-edge views and correct lens astigmatism that can prevent the ability to bring subjects into sharp focus. ED glass corrects for chromatic aberration to ensure colors are accurately rendered. Anti-reflection fully multi-coated 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'. A protective external lens coating helps to repel dust, water, and oil to ensure obstruction-free viewing. For longer glassing sessions, these binoculars are tripod mountable with an optional adapter.
