Buyer’s Guide

Having looked at 5 of the best long distance binoculars, it’s now time to think about what is important in finding the best long distance binocular. So let’s dive into the specifics as we go through some important features to consider in order to pick the right option for your needs.

Field of vision

This refers to the visible area that you can see through the binoculars without having to move it around. It is measured in feet per 100 yards and with higher magnification; it gets smaller as the objective narrows down on the subject.

Most people looking for a long distance binocular assume that since long distance binoculars are big with long lenses, they should have a wide field of vision. This is hardly the case. What you will find is that binoculars with a capacity for a wide field of view, whether big or small, are usually pricey.

This is because getting a wide field of view at a high magnification level requires more powerful optic performance for any type of binoculars. Therefore, be prepared to dig deeper for options that provide a wide field of view.

Lowlight performance

If you are going for a long distance binocular, you will need its optics to deliver the highest level of light transmission so that you distant images appear lifelike and bright enough for your viewing. For this reason, the low-light performance of your binoculars will matter.

For extreme night hunting, you will need more than regular long distance binoculars to get the job done. Perhaps a night vision binocular with an infrared sensor will do.

However, if you are only planning to stargaze with your long distance binocular, the internal light transmission and the magnification of your lens will do just fine.

Binoculars weight and Tripods

Long distance lenses tend to be huge and heavy. For that reason, it can be exhausting when you have no support and especially if you need to view your subject for extended periods. That is why most options come with a tripod adapter.

This allows you to get support for your tripod and as a result, you get to avoid shaky images that are out of focus. As an alternative to the tripod, there are a number of binoculars that come with an image stabilization feature.

How to choose binocular for long distance // Binocular for long distance buyer’ guide

These types of binoculars are usually top dollar options that use a battery for the active image stabilization mechanism. If you really need image steadiness with your binocular these can present a good alternative, however, using your tripod will work fine too.

Comfort and body durability

For a binocular, comfort begins with the grip. If you are planning to move around with your binoculars, you will need one that features decent rubber armor which will also provide a reliable non-slip grip.

While the rubber armor works well to establish a strong grip, it also gives the binoculars a rugged feel that is shockproof. This adds an extra layer of protection to your lenses.

You will also want to get binocular with water and fog resistance. This will prevent fog or dew drops from getting into the binoculars to distort your viewing.

If you are going for durability, you will also have to think about the material used to make the chassis of the binocular. Here are some of the most popular options that most manufacturers use.

Aluminum

It’s preferred for its corrosion resistant capacity. It’s also a lightweight material that is easy to work with yet strong and durable.

Polycarbonate

This material is also easy to work with and its main advantage is that it is temperature resistant to the protection of the optics inside the lenses. Its temperature resistant properties make it a good fit for binoculars built for extreme weather conditions.

Magnesium

This is another metal alloy that most manufacturers use due to the high strength to weight ratio it provides. It is a good pick for those who are looking for lightweight long distance binoculars.

Magnification and objective lens diameter

Binoculars are categorized by their magnification and objective lens diameter. That is why you will a set of numbers like this 20×60, 10×50 with every model. The first number in the equation represents the magnification of the binoculars and the second number stands for the objective lens diameter.

Most long-distance binoculars have a high magnification number to enable them to magnify objects from a long distance. The objective lens diameter, on the other hand, determines how much light can be gathered to make your distant image look bright and clear.

As a result, the bigger the magnification and objective lens diameter the better the image quality from your long distance binoculars.

Variable magnification

Variable magnification is only possible with zoom binoculars. These usually have a number such as 20-30×60.

Zoom binoculars offer great versatility however, they tend to present images with low sharpness and contrast. Generally, the image tends to suffer as you move through the magnification range.

Exit pupil

The size of the focused light hitting your pupil when you look into the binoculars is the exit pupil.  The size of the exit pupil is supposed to be bigger than the diameter of your pupil.

This way, more light from the image hits your eyes and your view is sharper and clearer. On the other hand, with a small exit pupil what you end up with is a view similar to peeping through a hole.

You can easily determine the exit pupil by dividing the magnification to the objective lens diameter.

Eye relief

Eye relief – this is the distance between your eye and the eyepiece. If you plan to use the binocular with your glasses on this feature should be among the top in your list.

This is because it will determine the comfort of your viewing. Most options offer an eye cup that positions your eyes at the optimal viewing distance. You can also go with options that have a dioptric adjustment knob that lets you fine-tune the focus according to your eye prescriptions.

Prism system

Binoculars need prisms to orient the image for clear viewing. There are only two prism designs out there. They include:

  • Porro prism: prisms in this system are arranged at an angle with the eyepiece being offset from the lens tubes. This system produces bulkier binoculars.
  • Roof prisms: in this system, the prisms are arranged in a streamlined position for a compact body. This is a common system in the more expensive binoculars.

Lens coating

From prisms to lens coating. Here, what you need to know is that when the light hits the glasses of the lenses and the prism, it tends to bounce back though reflections. As a result, some of the light is lost and the image becomes blurred and out of focus.

With a layer of anti-reflective coating, your binocular will be able to achieve high levels of light transmission for a clear image. There are three level of coating and they range from coating, multi-coating and the fully multi-coating design.

The coating levels represent the number of surfaces in the binocular with the coating layer. The top level is the fully multicoated design that is capable of over 90 percent light transmission.

Type of Glass

The type of glass used to make the lens and the prisms of your binocular need to have a high refractive index for you to achieve high levels of light transmission for image clarity.

BaK4 is one of the best options you can have as it boasts of a high refractive index and it is considered one of the top materials for prisms. Other options include BK7 and SK15.

Conclusion

Those are the main features to keep in mind while looking for the best binoculars for long distance. We have categorized our list of the top 5 according to budget, durability and the different needs you might have so as to be sure to check all boxes.
