The eminent Japanese manufacturer of photographic equipment Nikon feels very well in the field of optical devices. Therefore, it is not surprising that his binoculars are highly valued among both amateurs and professionals.

Zoom

As the name implies, the universal model Nikon Aculon A211 8-18x42 boasts an adjustable magnification factor (from 8x to 18x). Changing the diameter of the exit pupil is carried out using a lever mechanism located on the upper face of the housing. When zooming, this indicator can vary from 5.25 mm to 2.3 mm. Accordingly, with an increase in the magnification of the approximation, the angle of the field of view and the aperture ratio will decrease.

High aperture

At minimum magnification, the binoculars provide a field of view of 80 m (at a distance of 1 km to the object of observation). Due to the high twilight factor, which is 18.3, as well as the presence of elements with a multilayer antireflection coating in the design of the binoculars, the optical device forms a clear and detailed image in low light conditions. However the large diameter of the lenses affects the overall weight and dimensions of the binoculars — it weighs 825 g and takes up quite a bit of space.

Versatility

Most often, tourists, hunters and nature lovers pay attention to binoculars. They can observe objects of interest from a distance of 13 m without worrying much about possible mechanical damage — the body of the optical device is shockproof. It also features a 1/4" tripod mount and diopter adjustment on the right eyepiece for those with imperfect vision.
