Product description The B&H Binocular Buying Guide Read More Nikon's black 10-22x50 Aculon A211 Binocular is an ideal device for hunters, birders, and avid outdoor enthusiasts who require a range of magnifications for wide-field and detailed observations in all light conditions.This version is outfitted with large 50mm objectives to draw in copious amounts of light and ensure bright and clear views in challenging situations like at dawn or dusk, or when peering into dense underbrush. Anti-reflection multi-coated aspherical lenses, made with environmentally friendly Eco-Glass elements, complement the BAK4 Porro prism light path to deliver high-contrast images with enhanced depth of field without edge distortion, and accurate color fidelity.The Aculon's sculpted rubber-armored housing is designed to fit comfortably into the observer's hand and provide a secure non-slip handling. A thoughtfully placed lever located next to the right eyepiece is easy to find with the thumb without having to take the binocular away from the eyes—putting control of the 10 to 22x magnification range at the observer's fingertips. Its zoom range and large objectives can make holding the A211 steady for long periods of time challenging, so Nikon includes a tripod adapter that allows it to easily mount onto a support system for hands-free use without the vibration, shake, and arm fatigue that can occur when holding powerful optics like this.The combination of image quality and user-friendly design make the 10-22x50 Aculon A211 a natural option for intermediate- to long-range glassing. This model of the A211 comes complete and ready to use in convenient clamshell packaging. - Optical Performance
