Good binoculars will serve you faithfully for many years, and provide excellent approximation with a clear picture of the image. How to choose binoculars of such a level that would meet the requirements that apply to it? Today we will try to highlight the most significant parameters that should be followed when choosing a high-quality device.
- Manufacturer's choice. You need to know that the choice of the manufacturer of optical equipment should be approached very carefully, since this area is very difficult to manufacture. That is why it should pay attention to global companies such as Canon, Olimpus and others. However, domestic manufacturers should not be discarded, since many companies are still producing high-quality optical devices, which in terms of quality are no worse than global European brands. So, for example, Belarusian binoculars are very popular among our compatriots, as the most reliable models that tolerate hiking conditions.
- The increase or the multiplicity of the apparatus. This parameter is the ratio between the size of a specific object that we observe with the naked eye and the picture that we can see in the camera lens. Typically, the magnification of binoculars varies from 3x to 22x zoom, depending on what they are divided into devices of small, medium and large magnification.
- The diameter of the entrance and exit pupils. A fairly serious parameter, which determines the ability of the binoculars to transmit images in low light. After all, how to choose binoculars if we do not know the level of perception of light rays? The designation of the diameter of the entrance pupil will help you choose a reliable binocular in which even in bad weather you can see the smallest details of the object in question. For this, a 40 mm thick lens will be enough.
- The angle of view and the resolution limit of the binoculars. The area of space that is viewed in the camera is measured in degrees and is its viewing angle. As for the resolution limit, this characteristic affects the image quality of the smallest details.
- Light transmission coefficient. It should be remembered that any lens has a reflective property, as a result of which about 5% of the light flux is reflected . If we take into account that a good binocular contains up to 10-12 lenses, then we can conclude that we lose up to 50% of the total number of light rays. If you are thinking about which binoculars to choose for hunting, then you should pay attention to this important parameter and purchase binoculars with a special antireflection coating.
- System and focus range. How to choose binoculars that can provide you with a high-quality image, and will be right for you. There are devices with the simultaneous adjustment of both lenses - a central, as well as a separate focusing system, which will be convenient for those people whose vision is slightly impaired.
In addition, you should also pay attention to the depth of field, relative brightness and the presence of aspherical elements. Carefully familiarizing yourself with the technical characteristics and knowing their functional purpose, you will be able to competently approach such a crucial business as choosing high-quality binoculars.
