What are different configurations of a Binocular? Used for Birding by BirdFeederist

Binoculars are the two telescopes that are aligned in the same direction to point out in the same direction to get a clear and good view. These devices allow the user to point out in the same direction with both eyes. These are very helpful in viewing distant objects. You can use the Binoculars to get the 3D dimensional view, unlike the telescope.

A Binocular can have different configurations and other features depending upon their prices. These configurations can affect the view of the objects depending upon their distance. Moreover, some people also prefer the different settings of the Binoculars depending upon their needs.

Various configurations of a Binocular                         

The best binocular can have different configurations from 10×42, 8×42, 8×32, and 10×26. Each configuration has its benefits according to their uses. Let’s see the various configurations of the Binoculars to know about the effects of these configurations.

1. Magnifications

Magnification is one of the most important things related to any Binocular. Whenever you go for buying a Binocular, you will see the Binoculars with different magnification. The most common magnifications of the Binoculars are 7x, 8x, 9x, 10x, and 12x magnifications. The magnifications of a Binocular can affect the Binocular in many ways. For example, the magnification can change the view and the performance of a Binocular.

When we talk about the higher magnifications, they can increase the detail of an image with a narrower field of view. Moreover, the higher magnifications decrease the brightness of the image as compared to smaller magnifications. It’s sometimes harder to keep the image still with the higher magnifications. So the smaller magnification Binoculars are usually good to see the nearer objects.

2. Objective lens size

A Binocular is mainly divided into four different categories depending upon the diameter of their objective lenses. For example, a compact size Binocular has a lens diameter between 21mm to 28mm, and a full-size Binocular has the lens diameter between 42mm to 50mm. The objective lenses can play an essential role in the overall size and the weight of the Binoculars.

The broader objective lenses are usually bigger and heavier as compared to the smaller objective lens sizes. The broader objective lenses give you a brighter image with better quality. Moreover, these are usually more expensive because they required more glass as compared to the smaller objective lenses.

3. Lenses quality and coating

A Binocular can have a different type of lens quality and coating depending upon their prices. The quality of any lens ensures the better contrast of the image. Moreover, the right quality lens provides the image is aberration-free. When we talk about the coating, it plays a role in reducing the reflected light. Furthermore, it helps the maximum light to enter. The more expensive and best lenses ensure the better image quality in less light as well with more light transmission. Moreover, they also prevent the colors from wash outing and distorting.

4. Exit pupil

The exit pupil is referred to as the image formed for your pupil to see. This image is usually formed on the eyepiece; you can get the exact pupil size by dividing the lens size with the magnification. When we talk about the maximum light, a 7mm pupil size gives the maximum brightness. This pupil size Binocular is perfect for the twilight and dark conditions. So the exit pupil size can affect the view and image quality in the twilight and dark conditions.

5. Eye-strain

The size, weight, and shape of a Binocular affect eye comfort. Usually, the low weight and small size Binoculars are perfect for the eyes. The regular Binoculars are generally hard to use after some minutes of use due to eye strain. But the high-end Binoculars are very comfortable for the hours of use without causing any eye strain.  You can easily use these Binoculars for hours with stretch features if needed.

6. Aiming

The aiming configuration of the Binoculars is also affected the image quality and view. You can set the aim of your Binocular from the middle of the Binocular settings. It usually depends upon your target and the distance from the target.

7. Waterproofing

Usually, all the Binoculars are waterproof, which makes them excellent outdoor devices. But some regular models can’t bear the water for more than a few minutes. So we can say that the waterproofing configuration of a Binocular can affect the usage time of a Binocular, especially in the rainy season.

What are the primary uses of the Binoculars?

A Binocular can be used for multiple purposes depending upon their lens diameter, magnifications, lens quality, and many other features. Just make sure you follow the right steps to buy perfect binocular. Let’s see some great uses of a Binocular.

  • Binoculars are handy for birders in observing natural beauty without disturbing the birds. You can easily see the birds from some distance without disturbing them. Binoculars are usually a fundamental tool for birders. The Binoculars with magnification 8x to 10x are very popular among the birders.
  • Some people also use Binoculars for hunting purposes. Usually, the hunters need the Binoculars to see the animals in the field where they are generally difficult to see the animals with naked eyes. The most famous Binocular among the hunter is 8x magnification Binocular.
  • The Binoculars have a long history of usage in the military. The soldiers use the Binoculars to know about their enemies’ move. Usually, the higher lens diameter Binoculars are used for this purpose.
  • The Binoculars are also used by the Astronomers for the general observation. They are handy in cornet and supernova seeking. The wide field of view of the Binoculars makes them very important in this field.


From all the above discussion, we can conclude that a Binocular has different configurations, which can affect the Binoculars in many ways. The most important configurations of a binocular are about the magnifications, lens diameter, lens quality, and the exit pupil. The higher lens diameter binoculars are usually good for distant objects. You just need to see the different configurations according to your need.
