In this ultimate guide, we will answer all these questions and more.
We will explain what binoculars are and how they work, what terms and specifications you need to know, how to select the best binoculars for your purpose,
how to use them correctly and comfortably, how to maintain and protect them, and what accessories you can get to improve your binocular performance.
By the end of this guide, you will clearly understand how to choose and use binoculars like a pro. Let’s get started!
Introduction to Binoculars
Binoculars are optical devices that use lenses and prisms to magnify distant objects and make them appear larger and more transparent.
They consist of two identical telescopes mounted side by side, one for each eye, that produce a three-dimensional image with depth perception.
The essential components of binoculars are:
Objective lenses
These are the large lenses at the front of the binoculars that gather light from the object you are viewing.
The diameter of these lenses determines how much light the binoculars can collect and how bright the image will be.
Eyepieces
These are the small lenses at the back of the binoculars that you look through.
They magnify the image formed by the objective lenses and bring it into focus for your eyes.
Prisms
These are glass or plastic elements inside the binoculars that reflect and bend the light from the objective lenses to the eyepieces.
They also correct the image orientation to appear right-side up and not inverted.
Focus wheel
This is a knob or lever that simultaneously adjusts the focus of both eyepieces.
It allows you to fine-tune the sharpness of the image according to your eyesight and the object’s distance.
Diopter adjustment
This is a ring or knob that independently adjusts the focus of one eyepiece.
It allows you to compensate for any difference in vision between your eyes and achieve a balanced image.
Eye cups
These rubber or plastic rings surround the eyepieces and provide eye comfort.
They also block out any external light that might interfere with your viewing.
Some eye cups are foldable or retractable to accommodate eyeglass wearers.
Hinge
This joint connects the two barrels of the binoculars and allows you to adjust the distance between them.
It helps you align the binoculars with your eyes and achieve a comfortable fit.
Understanding Binocular Terminology
When you shop for binoculars, you will encounter some terms and numbers that describe their specifications and performance. Here are some of the most important ones that you need to know:
Magnification
This number indicates how much larger an object appears when viewed through the binoculars compared to the naked eye.
For example, 10x magnification means an object will appear 10 times larger without binoculars.
Magnification is usually expressed as a single number (e.g., 8x) or part of a pair of numbers (e.g., 8×42).
Binocular Magnification Chart
I wrote some information on binocular magnification and how it affects the field of view, brightness, and image clarity.
I have summarized the results in a table below.
Please note that this is only a general comparison, and the actual performance and quality of the binoculars may vary depending on the brand, model, features, and accessories:
Magnification | Objective Lens Diameter (mm) | Field of View (degrees) | Exit Pupil (mm) | Brightness | Clarity |
---|---|---|---|---|---|
7×50 | 50 | 6.8 | 7.1 | High | High |
8×42 | 42 | 6.3 | 5.3 | Medium-High | Medium-High |
10×50 | 50 | 5.5 | 5.0 | Medium-High | Medium-High |
10×42 | 42 | 5.0 | 4.2 | Medium-Low | Medium-Low |
12×50 | 50 | 4.9 | 4.2 | Medium-Low | Medium-Low |
15×70 | 70 | 4.4 | 4.7 | Medium-Low | Low |
As you can see, the binoculars’ magnification affects the field of view, exit pupil, brightness, and image clarity.
The higher the magnification, the narrower the field of view, the smaller the exit pupil, and the lower the brightness and clarity.
The lower the magnification, the wider the field of view, the larger the exit pupil, and the higher the brightness and clarity.
The objective lens diameter also affects the brightness and clarity of the image.
The larger the objective lens diameter, the more light it can gather, and the brighter and sharper the image will be.
The smaller the objective lens diameter, the less light it can muster, and the dimmer and blurrier the image will be.
Therefore, when choosing binoculars, you must consider your needs, preferences, and your target’s lighting conditions and distance.
For example, if you want to see far and detailed objects in low-light or night-time conditions, you may choose binoculars with high magnification and large objective lens diameters, such as 15×70 or 20×80.
However, these binoculars will be heavy and bulky, and you may need a tripod or a monopod to stabilize them.
If you want to see comprehensive and bright objects in daylight or good lighting conditions, you may choose binoculars with low magnification and small objective lens diameters, such as 7×35 or 8×25.
These binoculars will be light and compact, and you can easily hold them with your hands.
Objective lens diameter
This number indicates how large the objective lenses are in millimeters.
For example, a 42mm objective lens diameter means that each objective lens has a diameter of 42mm.
Objective lens diameter is usually expressed as part of a pair of numbers (e.g., 8×42) or as a single number followed by “mm” (e.g., 42mm).
Field of view
This measures how wide an area you can see through the binoculars at a given distance.
It is usually expressed in degrees (e.g., 6°) or feet or meters at 1000 yards or meters (e.g., 420 ft/1000 yd or 140 m/1000 m).
A wider field of view means seeing more of your surroundings without moving your binoculars.
Binocular Field of View Chart
A binocular field of view chart is a way to compare the magnification and the width of the view of different binoculars.
The field of view is the area of the sky or the landscape you can see through the binoculars at a certain distance.
It is usually measured in degrees (angular field of view) or meters or feet per 1000 meters or yards (linear field of view).
The field of view depends on the magnification and the size of the objective lenses of the binoculars.
Generally, higher magnification means a narrower field of view, and larger objective lenses mean a wider field of view.
A good lot of thought for binoculars depends on your purpose and preference.
For example, if you want to observe wildlife or sports, you might prefer a wider field of view to capture more details and movements.
If you want to see distant objects or stars, you might choose a higher magnification to get a closer look.
However, there is a trade-off between magnification and field of view, so you must balance them according to your needs.
Here is an example of a binocular field of view chart that shows the angular and linear field of view for some ordinary binoculars:
Magnification | Objective Lens Diameter (mm) | Angular Field of View (degrees) | Linear Field of View (m/1000m) |
---|---|---|---|
8×42 | 42 | 8 | 140 |
10×42 | 42 | 5.6 | 114 |
12×50 | 50 | 5 | 87.5 |
15×70 | 70 | 4.47 | 77 |
You can use this chart to compare different binoculars and see how their field of view changes with magnifications and objective lens diameters.
You can also use the converters below to calculate the angular or linear field of view from one another:
- To convert the angular to linear field of view, multiply the angle by 17.5. For example, 8 degrees x 17.5 = 140 m/1000m.
- To convert the linear field of view to an angular field of view, divide the linear value by 17.5. For example, 140 m/1000m / 17.5 = 8 degrees.
Binocular Zoom Chart
A binocular zoom chart is a table that shows how different binocular configurations affect their zoom, which is the ability to magnify distant objects and make them appear closer.
A binocular configuration consists of two numbers, such as 8×42, which indicate the magnification power and the objective lens diameter of the binoculars.
The magnification power is how many times larger the object appears through the binoculars than with the naked eye.
The objective lens diameter is the size of the front lens in millimeters, which determines how much light the binoculars can gather and how bright and clear the image will be.
A binocular zoom chart can help you compare different binocular models and choose the best one for your needs.
For example, a higher magnification power will give you a closer view of the object but also reduce the field of view, which is how much area you can see through the binoculars.
A larger objective lens diameter will give you a brighter and clearer image, making the binoculars heavier and bulkier.
Therefore, you need to balance these factors depending on your intended use of the binoculars, such as hunting, birding, or astronomy.
Here is an example of a binocular zoom chart that shows some standard binocular configurations and their specifications:
Magnification x Lens Diameter | Exit Pupil | Twilight Factor | Field of View at 1000 yards | Weight |
---|---|---|---|---|
7×35 | 5 mm | 15.74 | 387 ft | 24 oz |
8×42 | 5.25 mm | 18.33 | 393 ft | 25 oz |
10×50 | 5 mm | 22.43 | 341 ft | 31 oz |
12×60 | 5 mm | 26.82 | 288 ft | 44 oz |
The exit pupil is the size of the circle of light that enters your eye when you look through the binoculars.
It is calculated by dividing the lens diameter by the magnification power.
The larger the exit pupil, the brighter the image will be in low-light conditions.
The twilight factor measures how well the binoculars can perform in dim light.
It is calculated by multiplying the magnification power by the square root of the lens diameter.
The higher the twilight factor, the better the image quality will be at dawn or dusk.
The field of view is how much area you can see through the binoculars at a certain distance. It is usually measured in feet or meters at 1000 yards or meters.
The wider the field of view, the easier it will be to locate and follow moving objects. The weight is how heavy the binoculars are in ounces or grams.
The lighter the binoculars, the more comfortable they will carry and use.
Binocular Strength Chart
A binocular strength chart is a way to compare different binoculars based on their magnification power and objective lens diameter.
It can help you choose the best binoculars for your needs and preferences.
For example, if you want to see more details of distant objects, you might prefer a higher magnification power, such as 10x or 12x.
However, higher magnification also means a narrower field of view, which is the scene area you can see through the binoculars.
A wider field of view helps find and follow moving objects like birds or animals.
A wider field of view also means less shaking and distortion of the image, especially if you hold the binoculars by hand.
Therefore, you might prefer a lower magnification power, such as 7x or 8x, for a wider field of view.
Another factor to consider is the size and weight of the binoculars. Generally, larger objective lenses mean more extensive and heavier binoculars.
More giant binoculars can be more challenging to carry and hold for long periods.
They might also require a tripod or a mount for stability.
Smaller binoculars are more compact and portable, but they might not perform well in low-light conditions or produce a dimmer image.
Therefore, you need to balance the size and weight of the binoculars with their optical performance and ease of use.
Here is an example of a binocular strength chart that shows some standard models of binoculars and their specifications:
Model | Magnification | Objective Lens Diameter (mm) | Field of View (degrees) | Weight (g) |
---|---|---|---|---|
Nikon Aculon A211 8×42 | 8x | 42 | 8 | 760 |
Bushnell H2O 10×42 | 10x | 42 | 6.5 | 709 |
Celestron SkyMaster 15×70 | 15x | 70 | 4.4 | 1361 |
Vortex Diamondback HD 8×28 | 8x | 28 | 6.2 | 397 |
As you can see, this chart compares different binoculars, and you see how their strength affects their field of view and weight.
You can also check our other binocular guide below to learn more about choosing binoculars for specific purposes, such as hiking, birding, or astronomy.
Exit pupil
This measures how large the circle of light that reaches your eye from each eyepiece is.
It is calculated by dividing the objective lens diameter by the magnification (e.g., 42mm / 8x = 5.25mm).
The exit pupil should match or exceed the size of your eye pupil in low-light conditions (about 2-7mm) to ensure optimal brightness and clarity.
Eye relief
This measures how far your eyes can be from the eyepieces and still see the full image.
It is usually expressed in millimeters (e.g., 15mm).
A more extended eye relief means using the binoculars comfortably with eyeglasses or sunglasses on.
Close focus
This measures how close you can be to an object and still focus on it with the binoculars.
It is usually expressed in feet or meters (e.g., 6.5 ft or 2 m).
A shorter close focus means using binoculars to observe small or nearby objects like insects or flowers.

Choosing the Right Binoculars: Understanding Size Charts and Specifications
A binocular size chart is a way to compare different binoculars based on their physical dimensions and weight.
Binoculars are usually classified into three categories according to their objective lens diameter, which is the size of the front lenses in millimeters.
The objective lens diameter affects how much light the binoculars can gather and how bright and clear the image will be. The categories are:
- Compact binoculars: Objective lens size is less than 30mm (8×25, 10×28, etc.)
- Midsize binoculars: Objective lens size is from 30mm to 40mm (10×30, 8×32, etc.)
- Full-size binoculars: Objective lens size is greater than 40mm (8×42, 10×50, etc.)
1. Compact Binoculars
The size and weight of the binoculars also depend on the magnification power, which is the first number in the model name.
For example, 8×42 binoculars have a magnification power of 8 and an objective lens diameter of 42mm.
A binocular size chart can help you choose the best binoculars for your needs and preferences.
For example, if you want to use binoculars for backpacking and hiking, travel, or concerts they are easy to carry and store. Good for quick looks at birds or other wildlife when you don’t need super detailed views.
- Pros:
- Very small and lightweight, easy to carry and store.
- Often more affordable than other types.
- Cons:

I hope this helps you understand a binocular size chart and how to use it.
Features to Consider When Buying Binoculars
Binoculars have various features that affect their performance and quality. Some of the most essential features to consider when buying binoculars are:
Magnification and objective lens diameter
These are the two numbers that describe the basic specifications of binoculars, such as 8×42 or 10×50.
The first number is the magnification, which indicates how much larger the object appears through the binoculars than with the naked eye.
The second number is the objective lens diameter, which indicates the size of the front lenses in millimeters.
The objective lens diameter affects the amount of light that enters the binoculars and the image’s brightness.
Field of view and exit pupil
These numbers describe the visual characteristics of binoculars, such as 330 ft/1000 yds or 5.25 mm.
The field of view is the width of the area you can see through the binoculars at a certain distance.
It is usually expressed in feet or meters per 1000 yards or meters.
The field of view affects how much of the scene you can capture and how easy it is to follow moving objects.
The exit pupil is the diameter of the circle of light that you see when you hold the binoculars away from your eyes.
It is calculated by dividing the objective lens diameter by the magnification.
The exit pupil affects how well you can see in low-light conditions and how comfortable your eyes are.
Prism type (roof prism vs. porro prism)
These are two prisms used to invert and correct the image in binoculars.
Prisms are optical elements that reflect and refract light.
Roof prisms have a straight and slim shape, while porro prisms have a zigzag and bulky shape.
Roof prisms are more compact, lightweight, and durable but require more complex coatings and alignment to achieve high image quality.
Porro prisms are more straightforward, cheap, and easy to produce but result in more extensive and heavier binoculars.
Coatings and lens quality
These factors affect the transmission, reflection, and absorption of light in binoculars.
Coatings are thin layers of material that are applied to the lenses and prisms to reduce glare, enhance contrast, and improve color fidelity.
Lens quality refers to the shape, material, and precision of the lenses that affect the image’s clarity, sharpness, and distortion.
Waterproof and fog-proof capabilities
These features protect binoculars from moisture, dust, and temperature changes.
Waterproof binoculars have sealed o-rings that prevent water from entering the body.
Fog-proof binoculars have nitrogen or argon gas in the body, preventing condensation from forming on the internal optics.
Ergonomics and weight
These factors affect how comfortable and easy it is to use binoculars.
Ergonomics refers to binoculars’ design, shape, size, and grip that affect how well they fit your hands and face.
Weight refers to how heavy or light binoculars are, which affects how long you can hold them without fatigue or strain.

Binocular Technology and Innovations
Binoculars are devices that have evolved and improved over the years, thanks to the advancement of technology and innovation.
Modern binoculars have incorporated various features and functions that enhance their performance, functionality, and convenience.
Some of the most notable binocular technology and innovations are:
Image stabilization technology
This feature helps reduce or eliminate the image shake caused by hand movement, wind, or vibration. Image stabilization technology can be either optical or electronic.
Optical image stabilization uses a gyroscope or a prism to adjust the position of the lenses or prisms to compensate for the motion.
Electronic image stabilization uses a sensor or a processor to detect the movement and crop or shift the image accordingly.
Digital binoculars and camera integration
These binoculars have a built-in digital camera or a connection to a smartphone or tablet.
Digital binoculars and camera integration allow you to capture photos or videos of what you see through the binoculars and store them in a memory card or a cloud service.
They also allow you to share, edit, or enhance images or videos with various apps or software.
Night vision binoculars
These binoculars allow you to see in dark or low-light conditions.
Night vision binoculars use either infrared or thermal technology to create an image.
Infrared night vision binoculars use an infrared illuminator to emit invisible light that reflects off the objects and is detected by an image intensifier tube.
Thermal night vision binoculars use a thermal sensor to detect the heat emitted by the objects and create an image based on the temperature differences.
Smart binoculars with built-in tech features
These binoculars have integrated various tech features that enhance their functionality and convenience.
Smart binoculars with built-in tech features may include:
- A GPS that can locate your position and track your movements
- A compass system that can indicate your direction and orientation
- A rangefinder system that can measure the distance and angle of your target
