The Nikon Aculon A211 10-22x50 Zoom 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 Poro prism light path to deliver high-contrast images with enhanced depth of field without edge distortion, and accurate colour 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.


  • Wide 10-22x zoom magnification range provides wide views at low magnification, with the ability to make detailed observations of distant objects at high magnification
  • Large 50mm objective lenses improve light-gathering ability for bright and clear images, even in challenging conditions such as at dawn and dusk
  • Traditional Poro prism light path produces a rich depth of field, allowing the user to discern the relative distances between objects in the view
  • High refractive index BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion
  • Aspherical eyepiece lenses correct spherical aberration to produce clear and crisp images, with reduced edge distortion and astigmatism
  • Anti-reflection multi-coated optics produce neutral and accurate colour fidelity and improve contrast and image brightness
  • 199-foot field of view at 1000 yards, on 10x power
  • All Nikon Sport Optics include a 10 year Nikon warranty

    Use and Handling

    • Ergonomically placed zoom lever allows user to adjust the zoom without removing binocular from the eyes with a simple movement of the thumb
    • Large slip-resistant centre focus wheel is easy to manipulate, even while wearing gloves
    • Left-eye dioptric correction compensates for individual user's optical prescription for clearer and sharper views
    • 56-72mm interpapillary adjustment range
    • Fold-down rubber eyecups for comfortable use with or without eyewear
    • 8.6mm eye relief at 10x power
    • Comfortable 5mm exit pupil at 10x will completely cover most pupils as they open and dilate in low light for a full and complete view without vignetting
