Explanation of the symbols on the binoculars
Numerical designations on the binoculars, such as. 8 х 40 or 7 х 50, refer to the magnification (8x, 7x) and lens diameter (40 mm, 50 mm). On models marked 8-24 х 50 has a variable magnification, allowing the magnification to be adjusted within the indicated range.
Choosing between lenses of different diameters
With the same magnification, but different lens diameters (e.g. 10 x 30 and 10 x 30). 10 x 50), it is important to bear in mind that a larger diameter lens will give a sharper, more contrasty image. A 10 x 50 binocular will give a more accurate image than a 10 x 30 binocular, but the latter is more compact.
Binocular “readiness” in different conditions
The diameter of the objective lens also influences the binocular's good performance throughout the day and in different weather conditions. Models with a lens diameter of 42 mm are often considered less effective in low light conditions than binoculars with a diameter of more than 42 mm, which work perfectly in low light, and binoculars with a diameter of 50 mm, which are effective even at night.
Binocular zooming
A designation such as 8-16 x 40 or 10-30 x 50 indicates the possibility of zooming, i.e. temporarily zooming in. These parameters indicate the range of magnification by which visibility can be adjusted.
Magnification and lens diameter selection
It is not recommended to choose binoculars with high magnification and small lens diameter, such as 22 x 32. These models have a high aperture but low illumination power, which negatively affects the image quality and functionality of the binocular.
