Nikon's black 10-22x50 Aculon A211 Binoculars are ideal 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 multicoated 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 binoculars away from the eyes—putting control of the 10-to-22x magnification range at the observer's fingertips. Their zoom range and large objectives make holding the A211s steady for long periods of time challenging, so Nikon includes a tripod adapter that allows them 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.

Optical Performance

  • 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 Porro 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 multicoated optics produce neutral and accurate color fidelity and improve contrast and image brightness
  • 199-foot field of view at 1000 yards, on 10x power

Use and Handling

  • Ergonomically placed zoom lever allows you to adjust the zoom without removing the binoculars from your eyes, with a simple movement of the thumb
  • Large slip-resistant center 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 interpupillary 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

Construction Details

  • Environmentally friendly Eco-Glass is made without lead and arsenic
  • Black rubber armoring
  • Ergonomically sculpted grips
  • Tripod adapter included for hands-free use to eliminate the vibrations/shakes and arm fatigue that are common when holding high-power optics
  • One-piece tethered ocular rainguard protects eyecups
  • Objective lens caps can be clipped to neck strap to avoid losing them during observation sessions
  • Weight: 33.9 ounces

Nikon did it again. Excellent!

I have tried more than one in this range for sky observation, and none is compared to Nikon 10-22x50 Aculon. To me the most relevant in a binocular is beside magnification, is precision, and the focus control has an excellent precision when we talk about focus. I strongly recommend this binocular.

This is the second pair of Nikon glasses I have purchased. I bought these based on the ability to vary the magnification from 10x-22x. These do exactly as advertised - clear glass, sharp images at high magnification, and not uncomfortably expensive. I would recommend them to friends

Shipping awful

These binoculars are a steal at the price - great optics, very nice grip, and zoom is awesome. I really enjoy viewing the Blue Ridge Mountains from my back yard and can’t wait to take them to the beach. They work perfectly for me and the shipping from B&H was super fast.

The product is better than we see in picture. And delivery is also faster than we expected.

When they arrived, my wife and I were inspired to go out on a road trip to see the beautiful vistas just south of our house up on Magazine mountain. We were blown away by the brightness and the flexible zoom from 10 X 50 to the 22X50 mm. It was worth the price when I spotted an eagle soaring and was able to zoom out and see it's feathers in the morning sun. We were so happy we decided on the Nikons with the zoom. Like having multiple pairs of binoculars.

How much does this weigh?
Asked by: Anonymous
Probably a couple pounds. Not something you would want to pack for hiking. They are very nice though. We use them to watch from our house.

What is the difference between this model and the #6489 model?
Asked by: Deborah A.
Compare the product highlights of the Nikon MFR # 8252 to the Nikon MFR #6489: the later comes in clamshell packaging (plastic) rather than the cardboard box of the former. The contents are the same.
