Fernglas UpClose G2 20x50 Porro

Describes the internal structure of a pair of binoculars, thereby further subdividing the different types.

A classic binoculars design, in which the objective lenses are slightly further apart than the eyepieces.

The second specification in the binoculars’ model number is the front lens diameter. The larger it is, the more light the binoculars collect.

The eye relief specifies the maximum distance from the eyepiece at which the entire field of view can still be seen. A suitable distance for spectacles wearers is >16mm.

A distinction is made between different glass materials. Through the use of special types of glass, the optical image can be optimized.

Binoculars are focused by focusing on the object, or rather the eyes of the observer.

The sharpness is adjusted via a central focusing wheel.

The binoculars’ magnification may be variably adjusted using either a lever or a scroll-wheel.

Compensates for the natural trembling of the hands. The picture is so stable, as if you were observing using a tripod.

An automatic or manual feature for measuring distances.

Watertight optics are equipped with special seals and are gas-purged. This is usually with nitrogen or argon gas. Since these gases are heavier than air, they cannot escape.

The angular field of view visible with the binoculars.

The shortest distance which can still be seen sharply through binoculars.

Used to compare binoculars’ performance in low light conditions. The higher the number, the more suitable it is for twilight. However, the value should always be considered in connection with the exit pupil.

Binoculars are usually equipped with an armouring that protects the binoculars and makes them easier to grip.

Unobtrusive and quick to hand!
