The Good
The Bad



There are so many good portable binoculars on the market to choose from. All you need to learn is what features matter most in terms of this type of products. In order to ease your job, we’ve gathered some useful information and made this buying guide that is showcased below.



Magnification and objective lens diameter

One important aspect when talking about small binoculars is the magnification power. The first thing you’ll notice in the product description is a set of two numbers, such as 8×35. The first number indicates the magnification of the binocular or to be more precise, how many times the object you are viewing with the naked eye appears larger.

The second one relates to the size of the front lens which is measured in millimeters. A large number means that more light enters the lens and the images resulted are brighter and clearer.

The reason why the objective lenses are quite important is that their size affects the weight and shape of the binocular. Therefore, portable and compact binoculars have in general smaller objective lens compared to larger items. The images might suffer a loss in quality, as well. But the advantage is that such an option can fit easily into your backpack or jacket pocket.

When in the market for the best mini binoculars, you need to understand that products that have a magnification of over 10x aren’t necessarily a good choice if you can’t control the shake of your hands.

Because they have a compact size and are easy of use, binoculars with smaller magnifications and objective lenses are more portable and practical.


Field of view

Depending on the purpose you intend to use the binoculars you will need a different field of view. This refers to how wide the scene you see through the binoculars is. If the magnification is higher, then the field of view will decrease substantially.

If you need binoculars for watching sports or birds, you’ll most likely need a pair that comes with a wider field of view. You need to pay attention to the information given in the number of meters that can be seen through the lenses at a specific distance.


Eye relief

Binoculars for sale come in different styles and have certain technical specifications that are suitable for specific purposes. For instance, the eye relief is a feature that refers to the distance that your eyes need to be from the binocular lenses.

You need to pay attention to this aspect because if your eyes get too close to the lenses, you will see a black crescent moon shape right in the bottom of the field view. On the contrary, if your eyes are too far away, you’ll see a dark ring around the field.

Eyeglass wearers need a tad more distance between their eyes and the lenses, so binoculars that have a 15mm eye relief and eyecups that can be twisted or folded down are a major plus.


Waterproof and fog proof

Many portable binoculars reviews recommend getting items that are built to face different weather and environment conditions.

In general, people purchase binoculars to use them outside for activities such as hiking, hunting, birdwatching or spectating music concerts. This is why you should invest in products that are waterproof. Models that are sealed with an O-ring enable the moisture from entering the binocular.

Especially if you plan on sailing with your boat, you’ll face conditions of fog when the visibility is quite reduced. Several binoculars on the market are outfitted with a special feature that consists of the air inside the binoculars being replaced with a gas that has no moisture content, like nitrogen or argon. If the product you buy has nitrogen purged in its description, then you’re good to go.
