Superior performance results from cutting-edge optics and lens technology in these Nikon EDG II 8x42 Binoculars that deliver amazing clarity and color in distant objects. Extra-low dispersion (ED) glass compensates for chromatic aberration. Dielectric high-reflective multilayer prism coating teams with multilayer lens coating and flatter lenses to provide sharp and bright images across the entire field of view, even at dawn and twilight. Phase-correction-coated roof prism enhances image resolution. Turn-and-slide rubber eyecups and a high-eyepoint design make use with sunglasses and prescription eyewear easy. The eyecups are horn-shaped and can be removed. The body’s short bridge makes these binoculars easy to grip. Rugged, waterproof design. Comfortable, ergonomically designed strap.
