Buyer’s Guide

Binoculars are intended for remote observation of nature or other objects. This product exists in great variety on the market so that it is difficult to know the model whose purchase constitutes a good investment. This buying guide aims to help you recognize the model that can meet your expectation.

Magnification level

The magnification of binoculars is a measure that causes a lot of confusion. But reading is simple if you know the meaning. It is only by making your choice based on this feature that you can find the model that suits you.

The magnification is in the form of figures such as 7 × 50. The first digit indicates the magnification factor while the second expresses the diameter of each objective. A 7 × 50 magnification allows you to see an object that is 100 meters away, 2 times 50, as if it were 14 meters away, 100 divided by 7.  The higher the magnification factor, the more the object appears close to the real distance where it is.

You should not be content to race for magnification if the intended use of binoculars does not require it. You may experience a tremor effect if the magnification is too high. Consequently, if the object observed is in motion, you will be hardly able to follow it.

There are circumstances that require having high magnification binoculars to better observe certain objects. You can switch to the comparison table after considering this feature.

The lens surface

The second point is the second number indicated (for example, 10 x 25), the 25 here represents the surface of the lens. The wider it is, the more the field of vision is, and the more the lens captures luminosity. You should know that many models present themselves as adapted to night conditions, often have nothing more than the others than large lenses and it is advisable to be wary of this indication.

However, a large number also involves heavier equipment and therefore has an impact on the weight of the binoculars. Their format will also be different, and if you need compact and light models, it is better to favor restricted lens formats.

Weight and size

The third point therefore obviously concerns the weight and size. It is difficult to find the perfect balance between strength, performance and lightness. For children or people who do not want to charge, the lightest models should be favored. This criterion is also very important, especially when hiking where the user must carry his equipment throughout the day.

A weight that is close to the kilogram can really be heavy in the long run, especially when you consider that the strap pulls on the neck and thus pulls it more and more forward as the day goes by.

The objective

The objective should be considered if you want to have a quality device that gives you a result that meets your expectations. This criterion determines the quality of the images.

The element to consider on this objective is its diameter. The latter is expressed in millimeters and is proportional to the field of vision that you can have. The field of vision is wider when this diameter is considerable and you can have more brightness to better see the object observed.

Be aware that binoculars with a large objective diameter are bulky. Objectives with a considerable diameter are synonymous with an important measurement both in terms of weight and volume.

Other features

The small details make the difference. Resistance to humidity, anti-UV treatment, non-slip coating, eyecups suitable for wearers of glasses, lens caps that are not lost at the slightest movement of air. These are little things, but they will make your experience even more enjoyable.

The quality of the glass and its processing should always be of high quality that not only minimizes reflections but also promises a long service life and can be repaired if in doubt. If the difference between two identical models is a few dollars, invest in a comfort model.


How can you maintain the optics of the binoculars?

You can get a lens brush and a rubber blow from a specialist optics store to gently remove dust from the lenses. However, raindrops should be removed with a tissue or a clean linen cloth that has been washed several times.

If you wipe off dust with a cloth, you will sand the lens surface matt over time and the optics will get an undesirable soft-focus effect. On the other hand, dried raindrops leave edges that can be removed by breathing on with the said paper handkerchief or linen rag.

What is the difference between 8 × 42 and 10 × 42 binoculars?

If you have to buy binoculars, you must first know how to identify the criteria that distinguish them from each other. The 8 × 42 binoculars, unlike the 10 × 42, offer a wider field of vision. It is precisely at this level that the difference is found between these two types of binoculars.

So if you want to get a “panoramic” view worthy of the name, 8 × 42 binoculars would be best. These have a wider field of vision, up to 20 to 30 meters. In other words, they stand within 20℅ of difference compared to 10 × 42 binoculars.

How to recognize a good pair of binoculars?

To help you better recognize a good pair of binoculars, you should first refer to the magnification and objective of the binoculars you need. Make your choice according to the diameter of the objectives. The amount of light depends on the diameter of the lens.

For better brightness, and better image quality, binoculars with larger lenses are recommended. Then consider the weight of your binoculars. And to go hiking or to venture into a forest, lighter binoculars will be essential to help you.

How to choose your marine binoculars?

To choose your marine binoculars, you must take into consideration criteria such as weight, luminosity, type of prisms, and above all its waterproofness. Since you are going to take your binoculars on board, you must make sure that they do not weigh more than 1 kg.

At the same time, a pair of binoculars with good brightness will be more practical and useful. As for its type of prisms, those in Porro are most often used, given its high optical quality.

Finally, we stress: it is essential to ensure the tightness of the device. This will protect them from moisture, as well as from dust.

How to calculate the magnification of binoculars?

It is important to know that the first number of the reference of a twin pair defines its magnification capacity. For example, for 8 × 42 binoculars, the subject you are looking at will appear 8 times closer through the binoculars. This means that even if the subject is actually 800m from you, it will appear to be 100m away.

How do night vision binoculars work?

In the binoculars of night vision, there is an element called an intensifier tube. It is responsible for projecting the image you are looking at through the binoculars. Since the principle with night binocular is not about magnification, they only offer magnification between 2x and 8x. The device also has objective lenses through which light enters. This then meets the photocathode of the intensifier tube.

On the other hand, the photocathode is responsible for producing high-energy electrons. These electrons are responsible for creating an image on the luminescent screen which is located at the back of the tube.


A pair of binoculars is worth considering for hikers, anglers, hunters, bird watchers, concert lovers, theatergoers and all other nature or culture lovers. Since there are many different binoculars on the market, you should think about the purpose for which you are looking for. Keep in mind, brightness and clarity undoubtedly remain the highly essential and priority characteristics to look for in binoculars for a flawless adventure.
