With legendary Nikon optical glass., multicoatd optics and improved chromatic aberration reduction provides bright, high contrast images with true color rendition in most lighting conditions. And internal texturing minimizes reflective light loss inside of the scope. Ergonomic and lightweight, the new body style is compact and very packable.A new focus knob has been placed on top of the scope for faster target acquisition and tactile rubber armor has been placed around the objective lens for improved grip and purchase. Nikon’s new built-in sliding sunshade both eliminates glare in bright conditions, and keeps dust and rain off the objective lens in rainy or dusty conditions. And like every model in the PROSTAFF line features waterproof, fogproof construction, nitrogen purged and O-ring sealed for legendary durability. A 20-60x zoom eyepiece with large ocular offers wide field of view for subject acquisition at 20x; and excellent detail resolution at 60x. With a turn-and-slide eyecup, this new eyepiece also offers enhanced eye relief.
