The 10x25 Premier LX L Binocular from Nikon is a pocket-sized set of glasses and feature a weather-sealed magnesium-alloy housing and an Eco-Glass optical path that contains neither lead nor arsenic. Phase-corrected roof prisms finished with a highly reflective silver coating allow the Premier binocular to preserve sharpness and color fidelity without sacrificing brightness. The magnesium-alloy housing is nitrogen-filled for fogproof performance and wrapped in a textured rubber armoring that provides a slip-resistant grip. A dual-hinge configuration allows the footprint of the binocular to be further reduced for storage in the side pocket of a day pack or even a cargo pocket. Complementing its image quality and compact footprint, the 10x25 Premier LX L displays a 50.5° apparent viewing angle and is capable of focusing as close as 10 ft, making this binocular suitable for almost any viewing task. Turn-and-Slide eyecups with multiple click-stop positions and a 15mm eye relief can provide a comfortable viewing distance for almost any viewer—with or without eyeglasses.
