Nikon Aculon A211 16x50 Binocular

Built for those who demand clarity at extreme distances, the Nikon Aculon A211 16x50 Binocular is the go-to optical companion for hunters, birders, and serious outdoor adventurers. Where other binoculars fall short in low light, the 50mm objective lenses pull in maximum light to keep distant scenes bright and well-resolved — even under heavy overcast or at dusk.

Optics That Perform When It Counts

At the heart of this binocular is a traditional Porro prism design powered by high-refractive-index BAK4 glass, producing a round exit pupil, exceptional depth of field, and impressively accurate color fidelity. Aspherical eyepiece lenses eliminate spherical aberration and astigmatism, while anti-reflection multi-coated Eco-Glass elements sharpen contrast and minimize edge distortion across every view. The generous 61° apparent angle of view and a 220-foot field of view at 1,000 yards make it easier to track moving subjects and reduce the visual effect of handshake — a real advantage at 16x magnification.

Designed for Long Sessions in the Field

The sculpted, rubber-armored housing offers a secure non-slip grip in any weather, while fold-down rubber eyecups and long eye relief keep fatigue at bay during extended glassing sessions. When arm fatigue becomes a factor, simply attach the included tripod adapter for rock-steady, hands-free observation.
