How to choose binoculars?
Today, choose binoculars both amateur and professional binoculars are chosen binoculars widely used in various fields of human activity. Tourists, hunters, sports spectators, and astronomy enthusiasts all frequently use binoculars. Even a trip to the theater for many is not complete without a small theater binocular, which is far from being just an accessory.
Quality binoculars are offered by many companies specializing in the production of optics or items for tourism and hunting. So, choosing a good optical device can be done without much difficulty. The main thing is to know what to look for.
Firstly, let’s understand the magnification. All binoculars are labeled with two numbers, for example, 20×40, which indicate such properties as magnification and aperture. In the example we provided, 20 is the magnification (power), and 40 (mm) is the diameter of the objective lens.
The larger the objective lens, the more light enters your pupil, making the image more contrasting even in low-light conditions. Lately, binoculars with variable magnification (so-called zoom binoculars) can be found. This is achieved through a choose binoculars lever or by rotating the front lens (similar to the zoom on a camera lens). In pursuit of high-magnification binoculars, one should not forget about the aperture, as image quality often proves to be more important than magnification.
The size of the exit pupil is the ratio of the aperture to the magnification. For a 20×40 binocular, it is 2 mm. This is a very small value (using such binoculars may cause discomfort and rapid eye fatigue), and the optimal range is considered to be 5-7 mm, which is close to the diameter of the human pupil.
Another important parameter is the field of view. It is not always specified in the name but is usually present in the accompanying description. The field of view is measured in degrees and characterizes the width of the area you can observe. Binoculars with a wide field of view are often called wide-angle binoculars and are widely used for observing sports events or during hunting when you need to keep a large part of the horizon in sight. It is easy to understand that there is an inverse relationship between the field of view and the magnification of the binoculars.
Magnification and Objective Lens Diameter
Binoculars are typically labeled with two numbers, such as 8×42. The first number represents magnification (8x in this case), while the second number indicates the diameter of the objective lenses in millimeters (42mm). A higher magnification allows you to see objects in greater detail but may lead to a narrower field of view. Smaller objective lenses make the binoculars more compact but may limit their performance in low-light conditions. Choose a choose binoculars magnification and objective lens diameter that suits your specific needs.
Field of View
Field of view (FOV) refers to the width of the area you can see at a specific distance. Binoculars with a wide FOV are excellent for activities like birdwatching, while those with a narrower FOV are better suited for detailed observations, like stargazing. The FOV is often inversely related to magnification, so balance these factors based on your intended use.
Lens Coatings
Lens coatings enhance image brightness and contrast, reduce glare, and protect the lenses. Look for binoculars with multiple coatings, such as fully multi-coated or multi-coated, for the best optical performance. Coatings improve the clarity of your view, especially in challenging lighting conditions.
Lastly, do not forget about the presence of multi-coating – sometimes called anti-reflective coating. To the eye, it looks like a choose binoculars colored film on the front lenses of the binoculars. Multi-coating allows for minimizing reflections, which results in more light reaching your eyes. This means you can observe more details in low-light conditions.
When choosing binoculars, don’t chase high magnifications. In tourist conditions, it is not always necessary. It is better to pay attention to a device with an optimal combination of characteristics. For example, binoculars with 4×30, 6×40, or 7×50 would be suitable for hiking, as they have good magnification (though not very high), a decent aperture, and an exit pupil size close to optimal.
You can purchase professional binoculars from leading world manufacturers such as Swarovski, Carl Zeiss, Canon, Nikon, and others at the store www.huntingshopfavia.com.
