Nikon A211 overview

  • 1Description

With its powerful magnification and large objectives, Nikon's black 10x50 Aculon A211 Binocular is an ideal device for hunters, birders, and outdoor enthusiasts who require an optic that delivers the capability of making detailed observations of distant subjects from dawn to dusk.

The enhanced light-gathering ability offered by the 50mm objectives helps to ensure bright and clear views, even 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. Despite it's 10x magnification, this version of the A211 has a wide 60° angle of view that helps to offset the appearance of visible hand-shake that is common with high-power optics such as this, while presenting the user with spacious views.

The Aculon's sculpted rubber-armored housing is designed to fit naturally into the observer's hand and provide a secure non-slip handling and is offered here in a subdued black color. Twist-up rubber eyecups and a comfortable eye relief enable easy viewing without eye fatigue, especially during long observation sessions. For those who might experience arm fatigue or visible hand-shake from holding a high-power/large objective optic such as this, it can be tripod mounted using an optional tripod adapter. The combination of image quality and user-friendly design make the 10x50 Aculon A211 a natural option for long-range glassing in even the most challenging light conditions.

Optical Performance
  • Powerful 10x magnification allows for detailed observations of distant subjects
  • Large 50mm objective lenses improve light gathering ability for bright and clear images, even 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 multi-coated optics produce neutral and accurate color fidelity, and improve contrast and image brightness
  • Wide 60° apparent angle of view reduces the appearance of visible hand-shake that is common when holding high-power optics such as this
  • 341-foot field of view at 1000 yards
Use and Handling
  • Large slip-resistant center focus wheel is easy to manipulate, even while wearing gloves
  • Right-eye dioptric correction compensates for individual user's optical prescription for clearer and sharper views
  • 56-72mm interpupillary adjustment range
  • Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter for hands-free use with reduced vibration and arm fatigue
  • 11.8mm eye relief allows easy viewing without eye fatigue, especially during long observation sessions
  • 5.0mm exit pupil 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
  • Protective rubber armoring provides a comfortable slip-resistant grip even in cold weather
  • Ergonomically sculpted grips

Nikon A211 reviews

10x50 Aculon A211 Binocular is rated 4.8 out of 5 by 20.
Rated 5 out of 5 by from 3 b's Bueno-Bonito-BaratoAdquiri un par de estos Binoculares para poder ver un concierto y ademas me prestaron uno mas de otra marca. Los de la otra marca Bushnell 16x50 que me prestaron no obsequiaban la misma calidad de imagen que los Aculon Nikon. Los Nikon ofrecen una claridad de imagen impresionante y mucho mayor alcance que los que me prestaron. Lo mejor es que la imagen se aclara en un concierto donde existe poca luz. Otra caracteristica que desconozco es que enfocabas el objetivo y entre 10 a 15 metos a la redonda lograbas ver todfo enfocado sin necesidad de cambiar el ajuste. Muy satisfecho con la inversion.

Rated 5 out of 5 by from Fabulous binocular for bird watching! These binoculars were a great purchase for bird watching. The clarity and definition can't be beat at this price point. My son and I each bought a set and we couldn't be more pleased.

Rated 5 out of 5 by from Great for Birding even at dawn/dusk These are bright, easy to use and extremely clear. I purchased them for bird spotting in conjunction with my Nature Photography - but of course will be used for mammals as well.

Rated 5 out of 5 by from Excellent Binoculars I was really wanting a telescope for star gazing but got talked into buying a good pair of binoculars first. I would still like a telescope for seeing planets up close and personal but am really glad I purchased these binoculars as an entry level (and cost effective) way of viewing the stars and moon. The view through these binoculars is clear as a bell and very easy to focus. If you are in the market for a quality pair of binoculars for star gazing (or bird watching) I would highly recommend these. I think the magnification is perfect unless you want to use a tripod. These binoculars come in a box with a strap and case as well as dust covers for the lens and eyepiece. I can really find no fault with these other than it would also be nice if they were waterproof. B&H did an excellent job of packaging and providing expedited shipping as well as the lowest price I could find anywhere. Excellent experience.

Rated 5 out of 5 by from good bang for the buck Good bang for the buck...very clear optics and adjustments allow me to compensate for differences in my eyes left to right. Not too heavy but better used with some elbow support as they are a bit hard to hold steady as any 10 power units are going to be..still a good value
