The Nikon 8246 Aculon A211 binocular promotes Porro Prisms to offer clear images for casual sports without paying too high. This prism uses light deflection to give the binoculars an offset look.

They use BaK4 prisms which are thick and durable with a round exit pupil to create crisp shots. The pupil also helps to prevent distortion on the edges of the glass when the light bounces through the housing.

The lenses are fully multi-coated to brighten the image even in low-light situations. The subjects will appear brighter on a cloudy day as well. There will be some color aberrations around the lens edges, but they do not stop you from enjoying the view.

At last, the traditional Porro Prism produces a vivid depth of field to ensure that users can recognize the distant subject. Nikon makes environment-friendly lenses, so they are lead and arsenic-free.

Focus and Field of View

The Nikon Aculon’s central focus knob is smooth and allows sharp focus. It happens so rapidly without jerky distortion or movement. The close focus distance is good enough to watch a soccer game from behind the stands. With the quick focus adjustment, the distance scale takes a 450 degrees turn.

Likewise, the field of view is relatively solid and flat, giving you 314 ft sight at 1000 yds. The wide-angle of view reduces shaking of hands which is normal while holding high-power optics.

Eyecups and Eyepieces

The turn-up and slide eyecups are comfortable even for those who utilize outer eyewear. These eyepieces are made from rubber to provide comfort when used for prolonged periods.

You won’t get distortion while adjusting them; thus, be carefree. Also, the inner barrels are well coated and made from matte. These aspherical eyecups correct the spherical aberration to give images with reduced astigmatism.

Optical Performance

Nikon 8246 Aculon A211 10×42 binocular has powerful 10x magnification that gives detailed observation of faraway targets. The 42 mm objective lens helps to enhance the light gathering ability to share clarity images.

Further, the optics are multi-coated with anti-reflection to get neutral and accurate color constancy. It also helps to improve the image brightness and contrast.

Construction Quality

Nikon believes in making environmentally friendly products, so the Aculon A211 10×42 binocular uses Eco-Glass. The entire device is covered in protective rubber armor to give a comfy grip and prevent it from slipping in wet or cold weather. The grips are ergonomically sculpted.

Likewise, the one-piece tethered ocular rainguard protects the eyecups and prevents them from getting scratches. The binocular is built with sturdy material, yet it is lightweight and feels good in hands.

They have a miniature design that makes them easier to use and carry all day. Further, the lens caps come with clips to attach to the neck strap and prevent loss.

Use and Handling

The large center focus wheel is slip-resistant and can be easily controlled while wearing gloves as well. Individual user’s optical prescriptions are compensated by right-eye dioptric for a sharper and clearer view.

Nikon 8246 Aculon A211 10×42 binocular is adaptable with a tripod that offers hands-free use to reduce arm fatigue and vibration. The 11.6 mm eye relief helps with easy viewing without giving fatigue to the eyes during long period observation.

Moreover, the wide exit pupil opens and dilates in low light to cover more pupils to give a complete view without vignetting.

Water and Shock Resistance

The Aculon A211 Binoculars are not fog proof, but they are water and scratch-resistant. The thick rubber armor resists shock and water, making it less slippery during wet weather.
