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.

Related Questions and Answers

Q: 1. Does it get longer of its own accord? I have an Eagle Optics (R.I.P.) harness that has stretched considerably in its 6-year life. The straps also tend to slip through the adjustment buckle, so the nocs hang lower.

A: The newer type of fabric should keep stretching to a very minimum in the Nikon ProStaff Suspender Harness Binocular Strap for many years to come.

Q: 2. Does the harness set include any hardware, like split ring, etc. to connect the harness to the binocular?

A: The Nikon ProStaff Suspender Harness Binocular Strap does not include split rings as they are not needed for most binoculars.

Q: 3. Does the Monarch M5 have better optica than the original Monarch 5?

A: No the Monarch M does not have better optics than the Monarch 5. I does have a slightly larger field of view and a newer type of optical coating on the elements.

Q: 4. I have read, in the Nikon web, that the aculon zoom models do not have aspheric lens. Is there any mlstake in the description of the item? It happens all over the wold web pages. Please advice.

A: We stand by our listed description.

Q: 7. With respect to my previous question and your answer regarding: Can the Nikon 847 Tripod connected / carry this Nikon 10-22 / 50 binoculars? and the answer: Yes, the tripod can support 4.4lbs and the binos weigh 2lbs. BUT my question is if the mechanical adaptors of both are the same, so the binocular can be attached to the tripod WITHOUT the need for additional adapter. Thanks in advance

A: You will need to use the included tripod adapter.

Q: 8. Waterproof??

A: The Aculon A-211 appears to be Water Resistant and grip well in Wet Weather--They are not completely Waterproof--

Q: 9. These binos are indicated to work with a tripod adapter/mount, but you don't seem to sell the adapter?

A: Nikon Monarch Binocular Tripod Adaptor BH #NIMATA • MFR #8177 would be the appropriate adapter for this model.

Q: 10. What is the difference between this model and the #6489 model?

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.
