Pentax 10x50 Z-Series ZD ED Binoculars

With an eye for the discerning nature enthusiast, the Pentax 10x50 Z-Series ZD ED Binoculars feature multiple optical technologies to improve the image quality and ensure accurate colors in all weather and lighting conditions - especially in low light, such as dawn and dusk when many birds and game are most active. The image-enhancement starts with the 50mm objective lenses that draw in copious amounts of light and extend the practical useable ability well beyond smaller objective optics. The lenses are made with hybrid aspherical elements and extra-low dispersion (ED) glass. The aspherical elements 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. ED glass corrects for chromatic aberration to ensure colors are accurately rendered. Anti-reflect fully multicoated optics maximize light transmission through the entire optical path to make views appear bright and crisp, especially in low ...
