Things to Consider Before Buying

Here we will discuss the important features that you should look for before picking any model of zoom binoculars. Amongst others, these include the magnification, objective lens; field of view, exit pupil, eye relief, and other design features such as fog and waterproof.


This is the important feature that sets the zoom binoculars from the fixed magnification binoculars. The fixed ones are often identified by the numbers, for example, 7×50 where the 7x is the magnification level and the 50 is the objective lens diameter in millimeters.

Beware of the fixed multiple magnification levels such as 7x/10x/20x. It doesn’t mean they are zoom magnifications but fixed magnifications.

The advantage of the zoom binoculars is that you have a product with multiple zoom capabilities. The zoom feature allows you to move from low to high magnification so that you can reveal as many details as possible of your target. It is actually a great feature for long-range viewing where you spot birds or watch a sporting game that is miles away.


However, higher magnifications are linked to a narrower field of view when viewing objects. The image may be difficult to reveal the finer details. In this regard, beware of the ridiculously high magnification levels because they will make your viewing a difficult task should you opt for the high magnifications.

When viewing objects farther away, try the lowest magnification to spot the objects and then zoom accordingly until you reveal the finer details. The lowest magnification gives you a wider field of view than you would start with the higher magnification level. Typically, the ideal magnification shouldn’t be higher the objective lens diameter.

Objective lens diameter

Usually, the lens diameter is indicated by the last number in the description of the product. For example, in Binger 10-30×50 zoom binoculars, the lens diameter is 50mm. It basically plays a significant role in providing clearer images to the viewer.

The higher the number of the binoculars objective lens diameter is the more light into the binoculars to see more details of the product.

So, if you have two products with identical features but different objective lens diameter, pick the one with the larger diameter as it will bring more light, more especially in low light conditions. Obviously, the larger diameters will impact the price of the product. For someone who is keen to invest in binoculars that should not be a problem at all. 

Exit pupil

The exit pupil is yet another important feature to look for because it tells you about the brightness of the object when viewed in unfavorably low-light conditions.

The number is measured in millimeters and it is determined by dividing the objective lens diameter by the magnification number. A larger exit pupil will give you the bright and crystal images.

Still, on the exit pupil, we have the relative brightness which is determined by squaring the exit pupil number. The higher the result is the more brightness the binoculars are. The feature is also imperative in low-light conditions.


But note that models do play a role here as well because the binoculars with identical exit pupil numbers do not necessarily indicate they have the same quality. The optical coatings, prism type, and the lens play a role in that.

Eye relief

The best binoculars are the ones that allow you to operate them without taking off your eyeglasses. This is made possible by the eye relief. Usually, the binoculars have the retractable eyecups to accommodate the wearers of protective glasses. You can adjust them to the minimum position so you can use the binoculars.

The eye relief is the distance between your eyes and the eyepiece. Make sure it’s sufficient to let you use the binoculars with the eyeglasses. The long eye relief provides more comfort of using the binoculars away from your eyes. Together with the eye relief size, check the adjustable eyecups for the convenience of your protective glasses.

Lens coatings

Normally, the light that passes through the lenses will be reflected away if not coated. The reflection diminishes the amount of light transmission and as a result, provides a blurred image.

Spy Glass Dawn Binoculars Spy Spying Birdwatching

Binoculars often feature multi-coated optics in a quest to reduce this light reflection so that you can have crystal and clearer images. For quality assurance, you must check if the optical lenses are coated whenever selecting any binoculars. 

Other features

These include features such as waterproof and fog-proof. If you are going to use the binoculars in an area frequented by fluctuating climatic conditions with downpours, it’s advisable to consider the waterproof binoculars.

Weatherproof products are not necessarily waterproof. Usually, the waterproof binoculars feature the O-rings that seal away the moisture from penetrating the product.

Fog-proof is also an important feature to look for especially when you move from one temperature setting to another. Fog can be damaging to your binoculars.


Also, check the warranties given by the manufacturers when buying these products. Most of these binoculars are expensive and prone to fall and get broken just after receiving the package. So, a product with no warranty puts you in distress.

Now that we have discussed the important features that you should look for, let’s devote time on the product reviews. We have highlighted the important aspects of each product.
