What Should We Pay Attention To When Buying Binoculars?
Posted by KeelyCarey on April 13th, 2021
Before giving advice on the right binoculars selection, hunting binoculars selection, optical binoculars for rifles, we need to give some technical information and basic concepts. After this information, we can move on to explanations about what to pay attention to when buying binoculars for whatever purpose.
Magnification Factor in Binoculars
The magnification factor is of course one of the most basic optical properties for a device whose main function is to zoom in on distant objects that are difficult to see with the eye. The first concept that amateurs who are interested in binoculars will encounter is the expressions in the form of 8 × 40, 7 × 50 on binocular models. There are also binoculars with zoom feature 8-24 x 50 - 12-60 x 70.
This expression, which will be frequently encountered in the world of binoculars, expresses two important parameters: the first number is used to indicate the magnification power and the second number is used to indicate the lens aperture. For example, a 7 × 50 binocular has 7 times magnification, 50mm lens aperture. In zoom binoculars, it is possible to zoom from 12-60 x 70, 12 times to 60 times magnification. This will be 1000 m./83 m.-1000 m./16 m in 12/60 floor approach. It is recommended to use feet in binoculars that approach 20 floors or more.
The higher the magnification power or the lower the aperture, the lower the brightness. Therefore, binoculars with high magnification factors may have difficulty showing dark objects. This is why; amateur astronomers place emphasis on light gathering power rather than high magnification in binoculars.
It is the most widely used type of binoculars in 7 × 30 daylight, as it provides a satisfactory result in terms of magnification power and image clarity. For night use, models of the same type of binoculars with 50mm aperture can be preferred.
The most efficient binoculars in terms of hunting are binoculars with a power of 7 × 50, 8 × 56, 9 × 63, provided that the brand and lens quality are good. However, it is very difficult to find other powers other than 7 × 50. Only private companies make binoculars of this power. Handheld binoculars used in the armed forces are generally 7x50mm binoculars.
Basic Concepts of Binoculars
In addition to the magnification factor and light gathering power, certain features make a difference between a wide variety of brands and models sold in the market, and the lack or insufficiency of some features reveal the quality of the device. Before evaluating the criteria we need to consider in our shopping, let's briefly go over the special terms that will help us understand these features.
Coating is a process applied to improve image quality in optical devices. It is realized through the evaporation of prisms, thin objects on lenses. Thanks to the coating, light losses are prevented and the image becomes clear. Appropriate and quality coating is one of the important factors determining the quality in binoculars as well as in most optical devices.

The focusing concept, which is also encountered in devices such as cameras and telescopes, is one of the important settings for binoculars. The clearest possible image is obtained for the point of view by adjusting the lens distances with a rotatable adjustment knob.
Center Focus Setting
In a dual scope, the center focus adjuster is used to adjust the sharpness of both parts in one motion at the same time. There are models in which the sharpness adjustment for both eyes is made with separate parts.
The exit hole is an optical value obtained by dividing the diameter of the objective lens by the magnification factor. While the large exit hole provides the advantage of brightness in low light conditions, the main thing to be aware of is that the exit hole fully matches the size of the eyepiece. While this harmony may differ from person to person, nowadays binocular exit hole sizes vary between 3-7 mm.
Field of view
Field of view is a measure that indicates the whole area that our binoculars focused on a certain point can clearly see around the focus point. The greater the binocular field of view, the wider the field of view. Wide field of view binoculars should be used while observing fast moving objects.
Dioptric correction is a tool that allows users with various eye defects to make their own specific sharpness adjustment on the binoculars.
They are large lenses located on the head of the binoculars and made up of different glass combinations.
It is the ability of electronic optical devices to clearly show the observed object by reproducing it point by point (pixel).
Eye Compatibility of Binoculars:
Check if the body of the eye fits your eyes.
As better binoculars hit the market at lower prices, it becomes important that you understand the optical technology behind the professional nature sports acceleration and be able to distinguish between low-tech optical devices. In other words, it is inevitable to be able to distinguish between good and bad in markets where all kinds of advanced technology binoculars are available.
