Binoculars

From professionals who use binoculars for observation purposes, to water sport, mountain sport, hiking, theatre, bird or plane enthusiasts: binoculars are hugely versatile when it comes to observing and spanning long distances. The multi-functionality of binoculars makes them ideal for trips, events, sports or nocturnal use.

Versatile magnification

Binoculars can be subdivided into two key types: roof prism (or penta prism) and the wider porro prism. The former directs light in pretty much a straight line to the eyes. The second type directs light via parallel prisms to the eyes. The choice is subjective, with weight and comfort playing crucial roles in decision-making. The 'best' magnification factor - the first number listed - primarily depends on the subject: on average, 7x is the most versatile. For theatre use it is 3-5x and for events and ball games it is 5-7x. For water sports or nature observation it is usually 8-12x and for bird and plane spotting it is often 12-20x.

Light intensity

The light intensity can be ascertained from the second number listed, usually between 30 and 50, and represents the front lens' diameter. An interesting value is the exit pupil value (the diameter divided by the magnification factor). This is an important visibility indicator in poor light. The greater the number, the better perception by the human pupil of the bincoular's image field. After all, in reduced light, the pupils enlarge. The same happens as we age.
