How to Choose Binoculars for Birding & Hunting (Step by Step Guidelines – 2019)

(How to Choose Binoculars): Choosing Best Binoculars is challenging. There is more binoculars optics ranging across multiple price points.

Regardless if your hobby is bird watching, hunting, nature, outdoors observers or something else, this article will help explain the different specifications, technical information and features of best binoculars you need to know before making a purchase.

Most of this post discusses all the confusing, technical information and other information’s that you are going to encounter as you buy.

The Features Need to Know About ‘How to Choose Binoculars’

When you shop for the best binoculars, it is inevitable that you are going to read shiny marketing details and designed to intend to buy that particular product.

To choose the best binoculars for your specific needs, it may be difficult to read a brochure or a salesperson’s line. Remember that each company has a mission to sell binoculars, so sales departments work to appeal to their product as much as possible.

The purpose of this section is to provide education. I want you to feel confident about choosing shopping and binoculars and start with these terms, numbers, features, and a firm understanding of what you will go through.

01: Magnification (How to Choose Binoculars)

Every binocular has two numbers in its description. For example, 7×42, 10×42, 8×32 or 12×50 etc. will show a combination.

The first number of features you read is magnification. So, 10×42 optics would have a magnification of 10.

Magnification is a quality that is enhanced through binocular, such as:

what is Magnification?, Magnification, magnification physics, magnification formula, what is magnification in biology, magnification calculator, lateral magnification, magnification microscope, magnification binoculars, total magnification,total magnification in binoculars, binocular magnification chart, which binocular magnification is better, which is the best magnification for binoculars?,
Magnification Strength

My recommendation: Try to choose binoculars that have an evolution of 7-10x. Anything above 10x usually provides so many measurements that the image will be vague because you cannot hold enough remote binoculars without a tripod.

If you do want magnification above 10x, then my recommendation: buy a binocular with tripod!

02: Objective Lens Diameter (How to Choose Binoculars)

The second number of the feature in a binocular is the diameter of the millimeter (mm), the objective lens diameter. So a 10×42 binocular is a objective lens diameter of 42mm.

Purpose lens is not closest to your eye; it’s the closest lens to what you are watching.

The objective lens size is important because it is responsible for the amount of light flowing through your binocular. The objective lens gets bigger and more-light that enters the binocular. More light is good because it allows you to watch better colors and bright images.


Do not use a wet cloth to rub the lens, use a dry and clean cloth or microfiber cloth to rub slightly.

My recommendation is to look for the binoculars in 30 – 42mm. A problem with a larger objective lens diameter is that it increases the overall weight. I like optics up to 30 mm and 42 mm because they seem to hit a sweet spot in performance and size.

30 mm The objective lenses below are generally considered to be compact binoculars because they are small and lighter, which makes the binoculars very much for children!

03: Close Focus (How to Choose Binoculars)

what is close focus?, close focus, what is focus?, close focus lens, close focus binoculars for butterflies, close focus monocular, close focus diopter, minimum focus distance calculator, minimum focus distance eye, celestron nature dx 8x42, close up lens canon, close up lens nikon,
Close Focus

Focus: Close focusing Get a measure of how often you can get your measurements (eg, birds, butterflies) and still get focus and get a clear picture.

Small you can get your close focus, good! Usually, it is considered to be some good less than 6.5 feet (2m). But again, it is better to compare the binoculars with this number, which has the same Magnification.

04: Field of View (The Visible Area Seen Through Your Binoculars)

Field of View (FOV) is visible only through the binoculars that you see through them. Think about FOV as the amount of action shown by your optics!

While watching birds or animals, small scenes may be frustrating because it’s easy to lose track of them as they move. Field of View (FOV) is measured in 1000 yards.

 field of view, what is field of view?, field of view calculator, field of view definition photography, field of view microscope, field of view binoculars, field of view compact binoculars, instantaneous field of view, monocular field of view, binocular field of view comparison,
Field of View (FOV) is measured in 1000 yards.

Many manufacturers will give the Angle of View instead of the Field of View (FOV). They represent the same thing, but you will need to convert the Angle of View to Field of View (FOV). To do this, multiple corners by 52.5. For example, if the Angle of View is 6.9 degrees, then FOV will be 362 feet. (6.9 x 52.5 = 362)

Field of View (FOV) is not related to the size of the objective lens diameter!

05: Porro Prisms vs. Roof Prisms

While selecting binoculars, you can choose two different prism styles you can choose.

Porro Prisms:

When the lens enters the lens, it is a zig-zag with a distance to reach your eyes. Until the roof prism was turned on the binoculars, these prisms were standard.

The most notable advantage of a bird prism is that they are cheaper than the roof prism, which means you can get high-quality binoculars for the same price.

The disadvantage is that the panoramic binoculars are more complex, holes, and almost strange to carry! I think they are very old and look out of style. I still have a hard time finding Porro Style binoculars for sale.

Roof Prisms:

The light of the roof prism allows your eyes to go directly through the barrel. Although the roof prism is smaller than the compact, streamlined and porro prism, internally it is even more complex.

Highly Recommended: Most hunter-gatherers and birds will be watching a telescope and a roof prism design. They are pretty easy to carry around and use. They are very good in your hands and the weight is low and the distance of Porro prism.

06: Waterproof and Fog-proof (How to Choose Binoculars)

Many times I went out and had to fight snow, ice or rain. I have fallen face first in mud and slipped into the hay. Fortunately, I do not have to worry about my optics in this situation and I recommend you choose a binocular with the following features:


Many companies use this term that water cannot enter. Generally, they may point out how far they can go before or how long they can go down the water. Make sure the binocular is waterproof and weather-proof.

Fog Proof:

In order to prevent your lens from being pushed into moist or humid conditions, your binocular needs to be replaced with dry nitrogen (or argon) gas instead of oxygen. Many times the details will be “nitrogen purged” or “nitrogen filled”.

07: Ease of Focus (How to Choose Binoculars)

Every optic focuses somewhat differently, so it is important to consider how easy it is to focus.

Is it easy and smooth or solid and tough to harden? Can you focus fast?

How to do focus?

  • Close your right eye then sight an object together with your left eye. Rotating the center focus wheel until the picture is sharp and clear.
  • Open your right eye then close your left eye. Rotating your right eye-piece until the object sighted is sharp and clear.
  • Both sides are now in focus. Need to use just the center focus wheel to focus on the other objects.

08: Warranty (How to Choose Binoculars)

Before you spend your hard money on expensive binoculars, consider whether a warranty is included.

In my opinion, a warranty for binoculars is a reflection of how confident their product is. Do they believe in their engineering? Will it hold birds, victims, or other outdoor use rigors and stress?

Many companies offer a “lifetime warranty” for manufacturer errors, but this does not include accidental drops or collisions that have occurred to you.

It is common for you to check your warranties but only for a limited time, for the loss of accidental damage. For example, during this writing, Get has included a 5-year counterfeit policy, which makes any damage due to regular and intended use!

According to my knowledge, these binoculars have all the features. If you want, can see it once.

Never look directly at the sun with your binoculars, as it may cause serious damage to your eyes, so be careful.

Conclusions and Recommendations – How To Choose Binoculars

We spent the last 1520 words talking about how to choose the perfect binoculars for you.

In short, here are my three recommendations:

Familiarize yourself with the technical features and features that are listed on each binoculars.

Set a budget. A decent set of dinner can cost as little as $ 100 and cost as expensive as $ 3,000. My guess is that most people read somewhere between these ranges. I think it is important to understand aspects that affect the value of the binoculars, so you know what you are paying to spend more money.

Most importantly, find as many binocular as possible and test! The only way to find the one that fits your hands perfectly. You can see many lenses, but it helps determine the amount of your desired measurements or the area of your choice.
