The body incorporates an ergonomically designed, rubber coated, ridged focus ring for quick focus and easy long-term focus maintenance. Both versions are compatible with common tripods as well as Nikon's exclusive Window Mount for steadier viewing from a vehicle.
The hearts of Nikon's Fieldscope 82mm ED scopes are their advanced optical designs and components. The lens glass is a select gradeof ultra-premium ED (Extra-low Dispersion) glass that is expertly ground and precisely polished for unexcelled image resolution. The lenses and high-index BaK4 prisms are coated with multiple layers of Nikon's own proprietary anti-reflective compounds to enhance light transmission, provide true color rendition, and deliver flare free viewing, making them ideal for spotting long range game or varmints, or discerning bullet holes in distant targets
Both new models incorporate a sliding sunshade for the objective lens that not only reduces the effect of glare on sunny days, but also serves to keep rain and dust off the objective lens in wet or dusty conditions.
The Nikon Fieldscope 82mm ED straight body measures 12.8" x 4.25" and weighs 56.4 ounces with 25x eyepiece. The angled body version measures 13.3" x 4.25" and weighs 56 ounces with the same 25x eyepiece. Both models close focus down to 46 feet, and provide a 256-foot field of view at 1,000 yards with a 25x eyepiece in place. Both versions are eyeglass friendly, allowing 14.5mm of eye relief.
