The black 8-18x42 Aculon A211 Binocular from Nikon is a handheld zoom optic with multicoated aspherical lenses and an ergonomically-designed housing. For the redesigned Aculon series, Nikon packages the Aculon A211 binoculars with environmentally-friendly Eco-Glass elements composed of responsibly-sourced arsenic-free material. The Aculon binocular's Porro prism design delivers enhanced depth of field, and its multicoated aspheric optical path deliver the image clarity and flat FOV demanded by nature observers.
Also new to the 2013 version of the Aculon binocular is a sculpted rubber-armoured housing that is designed to fit comfortably into the observer's hand and provide non-slip handling. Grooved ridges atop the housing and a generously-sized focusing wheel enable adjustments to the interpupillary distance and the point of focus even while wearing gloves. The lever located next to the right eyepiece puts control of the 8x to 18x magnification range at the observer's fingertips. The combination of image quality and user-friendly design make the 8-18x42 Aculon A211 a cost-effective option for intermediate to long-range glassing.
