The Nikon EDG 8x42 incorporates advanced optical technologies and thoughtful design elements to provide a premium viewing experience.
ED Glass Lenses: The binocular uses Nikon's Extra-low Dispersion (ED) glass, which effectively compensates for chromatic aberrations. This results in images with superior contrast and outstanding resolution, free from color fringing .
Field Flattener Lens System: A key feature for serious observers, this system minimizes field curvature. It ensures that the image remains sharp and clear all the way to the very edge of the lens periphery, not just the center .
Advanced Prism Coatings: The binocular features a combination of high-performance coatings. A dielectric high-reflective multilayer prism coating ensures consistently high light transmission (over 99%) throughout the visible spectrum for bright, vivid, and natural colors . This is complemented by a phase-correction coating on the roof prisms for high-resolution images .
User-Friendly Focus Mechanism: The large, easy-to-grip focus knob integrates the diopter adjuster. This clever design helps prevent unintentional changes to the diopter setting once it's been adjusted to your vision .
Comfortable Viewing Design: A high-eyepoint design provides a clear field of view for eyeglass wearers. The turn-and-slide rubber eyecups with a multi-click system allow for precise adjustment of the eyepoint. It also includes unique horn-shaped, detachable eyecups that block peripheral light for an unobstructed view .
Durable and Portable Build: Constructed with a lightweight yet durable magnesium-alloy body, it is wrapped in rubber armoring for shock resistance and a firm, comfortable grip. The "short bridge" design contributes to its superior ergonomics and secure handling .
All-Weather Reliability: The EDG 8x42 is engineered to perform in tough conditions. It is O-ring sealed and nitrogen-purged, making it waterproof (to a depth of 5 meters for 10 minutes) and completely fog-proof .
Environmentally Conscious: In line with modern manufacturing, all lenses and prisms are made from Eco-glass, which is free from lead and arsenic .
