Fernglas Hunter 2.0 8x42 ED

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

A compact and modern binoculars design, in which the objective lens and the eyepiece lie in a straight line.

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

42 is the answer to the ultimate question “of life, the universe, and everything” (according to Douglas Adams)

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.

Dioptre compensation can be used to compensate for differences between the right and left eye.

The interpupillary distance indicates how far the eyepieces or tubes can be pushed together or pulled apart. This is an important indication, since each person has a different interpupillary distance.

Coatings on optical surfaces have the job of minimising annoying reflections. In this way light transmission and contrast is increased.

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.

A 1/4" thread for connection to a photographic tripod. Most binoculars require an additional tripod adapter.

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.
