The Best Observation and Sight Binoculars
Binoculars are an optical instrument that is used to make long-distance observations and to spot even very distant objects. The binoculars are a valid support for those who love hiking, for those who practice bird watching, hunting, fishing and astronomical observations, but also more simply to enjoy the games at the stadium or a cultural evening at the theater. In this purchase guide, let’s see, which are the best binoculars to buy in 2018 and how to choose the most suitable for your favorite activity.
The Zeiss professional is currently the best binoculars ever, equipped with high-end HD lenses for ultra-refined observations in terms of both detail and color.
They have compact dimensions, which makes them particularly suitable for most activities. In addition, they are easy to transport and are built with superior quality materials, perfect as natural binoculars, even in adverse weather conditions.
As the best value for money, we recommend the best Chinese binoculars, the BNISE, with an integrated nautical compass to calculate the distance of objects and magnification 10×50.
The best astronomical binoculars for money value are the Bresser Astro 20×80, a pair of prism binocular glasses, 20x magnification, and equipped with a tripod connection, ideal for long observations.
Instead, we suggest Olympus Trooper 10×50 DPS, perfect for excursions and moving subject observation among the best economic binoculars.
The price range starts at around $40 for cheap binoculars and reaches $800 for top-range professionals. Depending on the type of activity and level of use, if you are looking for military professional binoculars, binoculars must be made carefully and consciously.

How binoculars work
The binoculars work through a simple principle: the image is reflected in the binoculars lens through the light, passes through the lenses, and is enlarged to the human eye. The image produced would be reversed to the observer’s eye. For this reason, glass prisms are inserted into the body of the binoculars, which overturn the image through a series of refractions.
There are different types with different characteristics and optics, and each is more suitable for use than another. Therefore, we must first consider what use we should do.
How to choose a pair of binoculars: Types and Characteristics
Depending on the use we want to do, to choose which binoculars to buy, we must evaluate the relationship between two factors: the number of enlargements and the lenses’ diameter.
We would have more or less brightness or more or less amplitude of the visual field from combining these two parameters. How can we know this data?
The combination is always indicated next to the model name and consists of two digits separated by an x. Thus, we can find 10×50, 20×80 binoculars, and so on.
The first digit indicates the number of enlargements, while the second indicates the diameter of the lenses in millimeters. Dividing the second number for the first, we will obtain a third value, called ” exit pupil,” also expressed in millimeters, essentially the optical system image’s diameter.
Depending on the use we prefer to make, we should choose the combination to adapt better. For example, the most versatile binoculars are 10×50, while those used for hiking, hunting, and bird watching are generally 8×42.
If we want to dedicate ourselves to celestial bodies’ observations instead, good astronomical binoculars should not be less than 20 × 80. Having clarified this important aspect, let’s see the other key features to be evaluated to make a good purchase.
Prisms
The prisms are the fundamental part of the binoculars because they are inverting the image, which otherwise would appear inverted. There are two types of prisms, Porro’s prisms, which owe their name to its inventor, and the roof prisms.
Porro prisms allow you to have a greater three-dimensional view of objects, even if these are very far away, and ensure greater brightness. However, this type of prism’s negative characteristic is its size, which is rather voluminous, and this also causes a greater weight in our equipment.
The second type of prism is the roof type. Roof prisms offer greater depth perception because they are composed of multiple reflecting surfaces. This could be a disadvantage because we could lose the vision’s sharpness if the surfaces are not calibrated. However, we can count on this type of prism’s compactness and its reduced size and weight on the advantages.
Lenses
The binoculars that are on the market can mount plastic or glass lenses. Plastic lenses refer to lower-quality images but are cheaper and more robust than glass. On the other hand, most products mount glass lenses because they have a higher yield and a higher quality, although they are more expensive.
The most commonly used glasses are BAK4 and BK7, the first used on high-end military professional binoculars, while the second is for medium-low-end models.
The problem of glass lenses is producing reflections, but this problem is easily solved because most models are equipped with anti-reflection treatment.
Focus
Focusing is used to visualize the object clearly and precisely and can be managed through a special wheel. Usually, this wheel is placed between the two eyepieces to be more easily managed while holding the binoculars.
In professional binoculars, we can find the independent focus, that is to say, that each lens is equipped with an adjustment ring, and you have to adjust them one at a time. We can adjust the focus differently for the right and left eyes. Cheap binoculars often feature automatic focusing.
Materials
As far as the binocular body materials are concerned, protective materials are usually used to protect against knocks and scratches. At the same time, guarantee a firmer grip on the instrument. The models designed for those who want to do water sports are often covered with non-slip and waterproof materials. The optical tubes are commonly produced in aluminum, a light metal alloy that does not weigh down the structure.
Weight
We should not underestimate the weight of the binoculars if our observation continues for a long time. For example, in bird watching, in astronomical observation, sometimes in some hunts where the same position is maintained for a long time, the binoculars must necessarily be light enough to be maintained even with one hand. In astronomical observations, the weight becomes more significant, given the increase in the activity’s lenses. Therefore, it is essential to have trestles or tripods.
