Nikon Aculon 16x50 Binoculars (A211)

The Nikon Aculon A211 family of binoculars feature quality and affordability. They are suitable for most activities, such as birdwatching and other nature viewing, astronomy, surveillance and surveying.

Nikon's Aculon A211's feature multicoated lenses fabricated with Nikon’s exclusive lead and arsenic free Eco-Glass™. This glass delivers astonishing clarity and precision in a lighter-weight. The BaK4 Porro prism systems within all Aculon A211 binoculars deliver a high quality image under a multitude of lighting conditions, making these binoculars effective from dawn till dusk.

Other excellent optical technologies are integrated into the Aculon A211 binoculars. Aspherical eyepiece lenses aid in delivering a flat field of view, while lens multicoatings enhances image brightness.

Turn-and-Slide rubber eyecups facilitates easy positioning of eyes at the correct eye-point, and allows for comfortable viewing during extended periods of use.

Smooth and fast central focus knob allows for quick viewing in addition to the Aculon A211's comfortable and ergonomic design.

16x50 binoculars are a full-sized, high-quality, and cost effective choice, offering high magnification to pull subjects in closer. The high magnification may appear more jiggly to some people, due to the higher sensitivity to movement. If you will be using these from a boat, we suggest going with a 7x or 8x model instead.

Nikon's Aculon line replaces the previous generation of Action binoculars.
