However, how to choose a binocular of such a level that would be ideal for you and would completely cope with all the functions assigned to it? To do this, you must purchase a good optical instrument, which will be a great helper for you on any journey. Good binoculars will serve you faithfully for many years, and provide excellent approximation with a clear picture of the image. How to choose a binocular 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 guide the choice of high-quality apparatus.
- The choice of the manufacturer.You need to know that the choice of the manufacturer of optical technology should be very careful, because this area is very complex production. That is why here should pay attention to global companies such as Canon, Olimpus and others. However, domestic manufacturers should not be discarded, since many firms are still engaged in the production of 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 well.
- Increase or frequency of the device.This parameter represents the ratio between the size of a particular object, which we observe with the naked eye and the image that we can see in the camera lens. Typically, the multiplicity of binoculars varies from 3x to 22x times the approximation, depending on what they are divided into devices of small, medium and large magnification.
- The diameter of the entrance and exit pupils.It is a rather serious parameter that affects the ability of binoculars to transmit an image in low light conditions. After all, how to choose binoculars, if we do not know the level of perception of light rays? Indicating the diameter of the entrance pupil will help you choose reliable binoculars, in which even in bad weather you can see the smallest details of the object in question. For this lens with a thickness of 40 mm will be quite enough.
- The angle of view and the resolution limit of binoculars.The area of space that is viewed in the camera is measured in degrees and is the angle of its view. 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 consider that good binoculars contain up to 10-12 lenses, then we can conclude that we are losing 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 it will suit you. There are devices with simultaneous adjustment of both lenses - a central, as well as a separate focusing system, which will be convenient for those people whose eyesight is somewhat impaired.
In addition, you should also pay attention todepth of field, relative brightness and the presence of aspherical elements. Having carefully studied the technical characteristics and knowing their functional purpose, you can competently approach such a responsible matter as the choice of high-quality binoculars.
