Buyer's Guide

Buyers Guide: Zoom Binoculars

You will need to consider the type and amount of zooming you are doing. Binoculars come in a variety of shapes and sizes.

Important Features to Consider Before Picking Zoom Binoculars

Field of Vision

It is the area of visible light that the binoculars can see without moving it. It is measured in feet per centimeter. With higher magnification, it becomes smaller.

People who are looking for long-range binoculars assume that because they have long lenses and large eyes, they must have wide fields of vision. However, this is not the case. You will be surprised to learn that binoculars that have a large field of view are often expensive.

This is because obtaining a large field of view at high magnification levels requires stronger optic performance for all types of binoculars. So be prepared to look deeper to find options that offer a wider field of view.

Performance in Low Light

You will want your long-distance binocular to have the best light transmission possible so distant images look bright and lifelike. Therefore, your binoculars' low-light performance will be crucial.

Weight of Binoculars and Tripods

Long-distance lenses are often heavy and bulky. In addition, it can be very exhausting to have no support, especially if your subject is difficult to see for long periods. Therefore, most options include a tripod adapter;

this will allow you to support your tripod, and you can avoid blurred or out-of-focus images. There are many binoculars available that have image stabilization features.

These binoculars, which are often expensive, use an active image stabilization mechanism that requires a battery. These can be a great alternative if you need image stability with your binoculars, but a tripod is fine as well.

Comfort and Body Durability

Comfort begins with the grip. You will be moving around with your binoculars, so you need one that has good rubber armor; this will provide a non-slip grip and a secure fit.

The rubber armor not only provides a firm grip but also makes the binoculars shockproof; it also provides extra protection for your lenses.

A water and fog-resistant binocular is also recommended; this will stop fog and dew from entering the binoculars, causing distortions.

Durability is also important. You need to consider the material used in the construction of the binocular chassis. These are the most common options used by most manufacturers.

  • Aluminum - It is highly resistant to corrosion. It is lightweight and easy to use, but it's strong and durable.

  • Polycarbonate - It is easy to work with; it protects the optics within the lenses from temperature extremes; this material is ideal for binoculars designed for extreme weather conditions because of its temperature resistance.

  • Magnesium - Due to its high strength-to-weight ratio, this metal alloy is also used by most manufacturers. As a result, this is an excellent choice for anyone looking for lightweight, long-range binoculars.

Magnification and Diameter of the Objective Lens

Binoculars can be classified by their magnification or objective lens diameter. You will see numbers such as 20x60, 10x50, and 50x50 for every model. The equation's first number represents the magnification of your binoculars, while the second number is the diameter of your objective lens.

Long-distance binoculars with a high magnification allow them to magnify objects at a great distance. In addition, the objective lens diameter determines how much light is gathered to make distant images brighter and clearer.

Therefore, the larger the objective lens diameter and magnification, the better the image quality of your long-distance binoculars.

Variable Magnification

Zoom binoculars are the only way to achieve variable magnification. These typically have a range of 20-30x60.

Exit Pupil

Exit pupil is the size of the beam of light that hits your pupil while you are looking through the binoculars. Your pupil's diameter should be larger than your exit pupil.

You will see more of the image, and it will be brighter. On the other hand, a small exit pupil will give you a view that is similar to looking through a hole.

The exit pupil can be easily determined by dividing the magnification with the objective lens diameter.

Eye Relief

This is the distance between your eyes and the eyepiece. This feature is important if you intend to use your binoculars with glasses.

It will affect how comfortable you view. Many options have an eyecup that places your eyes at the best viewing distance. Optional options also come with a dioptric adjustment knob, which allows you to fine-tune focus according to your eye prescriptions.

Prism System

To be able to see clearly through binoculars, you need prisms. There are two types of prisms available. These are:

  • Porro Prism: Porro prisms are set up at an angle, with the eyepiece offset from the lenses tubes. This system makes bulkier binoculars.
  • Roof Prisms: In this system, the prisms can be arranged in a more compact position to make them easier to fit into a small body. This system is common in more expensive binoculars.

Lens Coating

Everything from lenses to coating. You should know that the light bounces back through reflections when it hits the prism and the lenses. The result is that some of the light is lost, and the image becomes blurred or out of focus.

Your binoculars will have high light transmission and clear images thanks to an anti-reflective coating. There are three levels of coating available: multi-coating, coating, and fully multi-coating.

The coating level represents the number of surfaces covered by the coating layer on a binocular. The highest level of light transmission is achieved by fully multicoated designs that can transmit more than 90 percent.

Types of Glass

For high light transmission and image clarity, the glass used in the lens and prisms of your binoculars must have a high refractive index.

BaK4 is an excellent option as it has a high refractive index and is considered one of the most popular materials for prisms. BK7, SK15, and SK15 are also options.

Price Range

There are many price options for binoculars. Although we believe that you should pay for what you get in general, there are still great deals. But don't expect to see Mars in perfect detail.

Final Thoughts

Zoom binoculars are available in a variety of power levels. It is important to understand the purpose of your binoculars. Some binoculars work both day and night. Some work best during the day, while others are better for night.

Compact zoom binoculars can only be used during daylight hours. Because their objective lenses are small enough to collect light at night, the binoculars can be used during the day.

You need zoom binoculars that can work both day and night. A pair with a full-size objective lens (42 mm, 50 mm) is the best choice. They can also gather enough light from the target object for night vision.

These zoom binoculars rank among the top in their class. You can now decide which zoom binoculars to buy with the buyers guide we provided.

Additional Information

What does zoom mean in binoculars?

Continuously Variable Magnification
Zoom binoculars are binoculars with continuously variable magnification; the magnification range can identify them they have, such as 10--30x60 or 12-36x70. The hyphen signifies that the magnification range is variable, from the first to the second number.

What's the highest magnification for binoculars?

80x magnification
Oberwerk BT100XL-SD 100mm binocular telescope has the world's highest power. Furthermore, it can be magnified up to 80x.

How far can binoculars zoom?

A 20x20-vision human eye can see 30 miles without obstruction if there is nothing in the way. You can see up to 300 miles with 10x50 binoculars, which magnify normal vision by 10x10.

Should I wear my glasses when using binoculars?

If you wear glasses, make sure to retract your eyecups as they will hold the binoculars out of the eyes and allow in peripheral light.

Why are my binoculars blurry?

If you notice blurry images when you use your left eye to view the image, you will need to adjust your focusing ring in the middle of your binoculars. The focusing ring brings the object you are looking at into focus, while the diopter on your right eyepiece adjusts for differences between your right and left eyes.
