Overview: The Nikon Aculon A211 10-22x50 binocular is a
lightweight zoom binocular that can be used in a wide range of activities. The Aculon
A211 comes with a
neck strap, eyepiece and objective lens caps, and a soft, padded carrying case.
Zoom: The Aculon A211 zoom binocular has an easy-to-reach
zoom control knob on the right eyepiece for changing the magnification. By
rotating the knob with your finger, you can adjust the magnification from 10x to
22x. There are magnification markings at 10x, 12x, 15x, 18x, and 22x.
TRA-2 Tripod Adapter: Included with the A211 is the TRA-2
tripod adapter, which enables the binoculars to be mounted onto a tripod or
monopod. The TRA-2 simply screws onto the central shaft of the binoculars, and
has a 1/4" standard tripod thread and alignment hole for mounting onto a tripod.
Multi-coated Optics: The lenses on the Aculon A211 feature multiple
layers of anti-reflective compounds for excellent brightness and resolution. The
eyepieces have aspherical lenses to give you a flat field of view without
aberration. Nikon's Eco-Glass lenses are lead- and arsenic-free.
Focus Knob: The Aculon A211 has a smooth, central focus knob for
bringing your subject into focus.
Diopter Ring: The left eyepiece has a diopter ring for
adjusting the binoculars to your eyesight. A diopter index indicates the "0"
position, as well as "+" and "-" positions.
Eyecups: The turn-and-slide rubber eyecups make it easy to
position your eyes at the correct eye-point for the greatest comfort during
Rubber Coating: The body of the Aculon A211 has a durable
rubber-armored coating to give you a non-slip grip, and to protect the
binoculars in virtually any weather.
