Buyer’s Guide

How to choose a binocular? Mankind is constantly changing the surrounding reality. People want to drive faster, fly higher, know more about the world and see further. For the past four hundred years, the last aspiration is achievable due to a variety of optical devices. Of course, binoculars are definitely very popular equipment.

In this section, we will ruin main weak knowledge points and give some essential tips on how to pass this choice-challenge head-on. Ready, steady, go!

Magnification and Lens

When choosing any equipment, you have to pay attention to its main technical characteristics. For binoculars, this is magnification and diameter of the lens. These parameters are so important that they are traditionally indicated by the manufacturer in a model’s title. For example, 10×42 means that the binoculars have the 10-times magnification and lenses with a diameter of 42 mm.

The majority of binoculars have fixed magnification. However, there are models with zoom, which is a variable magnification. At first glance, the latter option is preferable since it is more versatile and offers greater adjustment capabilities. But in practice, zoom binoculars lose in image quality to models with a fixed magnification noticeably. This is especially true for low-budget devices. In this case, the complex zoom element can be hardly performed at a decent level.

The lens is traditionally responsible for the most important role. In simple words, it must collect enough light and construct an image of the object of observation in the focal plane. The task of the eyepiece is to help consider the picture built by the lens. We can describe this element as an ordinary magnifier.

Let us be more precise. The binoculars of 25 mm diameter are great for a daytime-use. Their distinguishing feature is a compact design. The models with 30-40 mm diameter are suitable for observing during the day and considering the main objects at dusk. Besides, these products are still quite compact and convenient in use. Then, equipment with larger lenses is more specific and dedicated to a minimal number of needs. In addition, they require tripods because they are too heavy for hand-use. For instance, binoculars with 70 mm diameter and more are awesome for survey observations by sailors and the military.

Construction

First of all, the body of binoculars must have sufficient strength so as not to break and not be damaged when dropped. The shockproof indicator depends on the fact whether the body is rubberized. Thanks to this feature, binoculars are firmly held in hands.

Another property to pay attention to is binocular’s water resistance. Modern models can be so fluid-tight that moisture will not penetrate into them, even if they fall into water and stay there for some time.

Protection against lens fogging is achieved by filling the space between the lenses with nitrogen. This technique helps the lenses not to fog up even during sudden changes of temperature.

There are also binoculars with special features, such as built-in compass, laser rangefinder or image stabilizer. You can use these elements to solve many non-standard tasks. As a rule, the price of such advanced equipment is several times higher than of common models with similar characteristics but without special options.

Field of View

Another important characteristic of binoculars is its field of view. It can be indicated in degrees and linear magnitude from a certain distance. For instance, it can be 110 m from a distance of 1000 m, or 372 feet from a distance of 1000 yards. This parameter is inversely related to magnification. As a rule of thumb, the more powerful the binocular is, the smaller its field of view is.

Exit Pupil Parameters

In the pursuit of high magnification, many users forget about such an important parameter as the diameter of the exit pupil. Simply put, this is the diameter of the light flux that leaves the eyepiece to the observer’s eye. Calculating it is very easy. For that, you need to divide the diameter of lens in millimeters by the binoculars’ magnification. For instance, with 10×50 equipment, the exit pupil will have a size of 5 mm.

The larger the exit pupil is, the more light will reach the lens of the eye. In the daytime, human pupil narrows to 2-4 mm. But with the arrival of twilight and night, it can expand to 6-8 mm. If for observations on a clear, fine day, the exit pupil of 5 mm can even be a bit too much, then at night you need more.

Transparency

Naturally, when light passes through the optical system, some reflection and absorption losses occur. Due to that, the brightness of the resulting image decreases. When viewed through binoculars, objects look less illuminated than without it. Moreover, the more complex the optical device is, the greater these losses are.

The transparency coefficient is the ability of a binocular to transmit light rays, denoted by a metric fraction. For example, if the loss is 40% of the light, then the transparency coefficient is 0.6. Therefore, the maximum value of the transparency coefficient is equal to one.

Losses of this kind are in no way related to field of view or the binoculars’ magnification. To reduce or even eliminate them, customers use measures such as optical illumination. In more details, that is the use of a special transparent coating on the surface of optical elements. This action helps reduce optical distortion and light loss, thereby improving the quality of the image under consideration.

FAQ

1. What is the distinguishing feature of binoculars?

Unlike other optical tools, binoculars provide stereoscopic vision. Comfortably observing with two eyes, you can feel the volume of the picture. The greater the distance between the lenses of the device, the brighter this effect is.

2. How do Porro and Roof prisms differ?

Porro prism binoculars are classic and the most popular. This erecting system allows you to achieve high light transmission and a wide viewing angle. The binocular lenses are spaced apart. Also, they are not on the same optical axis as the eyepieces. Porro prism binoculars promote achieving a stereo effect and provide a three-dimensional image. Due to the so-called phenomenon of total internal reflection, this prism causes the fact that the loss of light on the entire system is practically zero (if you do not take into account the absorption of light by glass). Compared with Roof prism devices, this equipment possesses larger bodies.

In binoculars with Roof prisms, the lens and the eyepiece are located on the same axis. Unlike the Porro prism gadgets, they are lightweight and therefore more convenient in use. This advantage can be important for extreme sports enthusiasts, climbers, hunters or bird watchers. They travel a lot with binoculars through the woods or in the mountains and appreciate small size. However, Roof prism equipment is usually more expensive. It requires perfect precision grinding and polishing to produce high-quality images.

3. Which binocular accessories are necessary to buy?

The main accessories are usually included in the kit. For instance, these elements can be a strap for carrying the device on a chest, a cover for safe and convenient transportation, and a bracket. However, the tripod is not on the list. If you select a relatively big binocular, then you can definitely decide to purchase a suitable tripod for it.

4. What should people consider first when they are looking into buying a new pair of binoculars?

The first thing to think about is how and when you plan to use your binoculars. This equipment tends to be split into two different types: compact models and standard size models. The first option is great for a city break or a day trip out. Compact models can be packed easily into your hand luggage or fit into a coat pocket. Standard size models are more preferable if you want to achieve a highly-qualitative image. With their large objective lens diameter, you can observe objects well even in low-light conditions.

There are some other essential parameters to think about when decision-making. In our Buyer’s Guide section, you can get acquainted with them. Have a pleasant reading!

5. Is there a universal binocular?

Without a doubt, you can choose a binocular with medium parameters. For instance, 10×42 models are usually highly recommended. But everything depends on the purpose of use. In general, there are a lot of their types. For instance, theater and children’s binoculars possess a pleasant souvenir performance. With simple optics, they allow customers to achieve an acceptable picture with such compact sizes. Naturally, this equipment is unsuitable for hunting. In this perspective, Porro prism devices will be the best solution to consider. Nature and birds observers prefer a classic 50 mm binocular with really high-quality optics.

Conclusion

All in all, binoculars are a solid investment for a pretty large audience. Of course, you can use it for specific needs like hunting. But even newcomers will find this product precious and advantageous. With it, anyone can take a better look at the surrounding nature or observe the beauty of the sky and stars.
