Nikon 7x50 Aculon A211 Binocular

Nikon 7x50 Aculon A211 Binocular
Regular price 525.00


Pairing a relatively low magnification with large objectives, Nikon's black 7x50 Aculon A211 Binocular is outfitted with enhanced light-gathering capabilities, a large exit pupil, and long eye relief, which work together to produce an optic that is optimized for use in challenging light conditions.

The light-gathering ability offered by the 50mm objectives helps to ensure bright and clear views at dawn and dusk, or when peering into dense underbrush, while the large exit pupil ensures complete coverage as pupils open and dilate as light fades—which keeps views bright and clear without vignetting. 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, as well as accurate color fidelity. All these features work together to present users with an immersive observational experience.

The Aculon's sculpted rubber-armored housing is designed to fit naturally into the observer's hand and provide secure non-slip handling. It 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 from holding a large-objective optic such as this, the binocular can be tripod mounted using an optional tripod adapter. The combination of image quality and user-friendly design makes the 7x50 Aculon A211 a natural option for medium-range glassing in even the most challenging light conditions.
