How to Choose the Right Binoculars: The Complete Buyer's Guide
When buying binoculars, it's easy to become overwhelmed by the number of options available. Magnification, lens size, field of view, coatings, glass types, waterproofing, weight, and price all play a role in choosing the right pair.
The reality is that there is no single "best" binocular. The best binocular is the one that suits how and where you plan to use it.
This guide will help you understand the key specifications, what they mean in real-world use, and how to choose the right binoculars with confidence.
Why Choosing the Right Binocular Matters
Many people assume that more magnification automatically means a better binocular. In reality, this is one of the biggest misconceptions.
A binocular that performs exceptionally well for birding may not be ideal for hunting, while a binocular designed for long-distance wildlife observation may be unnecessarily heavy for travel.
Choosing correctly means you'll enjoy:
- Better image quality
- More comfortable viewing
- Less eye fatigue
- Greater confidence in the field
- A product you'll enjoy using for many years
Understanding a few key specifications before purchasing can save both money and disappointment.
Understanding Binocular Specifications
One of the first things you'll notice is a number such as:
These numbers tell you almost everything about a binocular.
The First Number: Magnification
The first number indicates how many times closer the object appears.
For example:
8x
Objects appear eight times closer.
10x
Objects appear ten times closer.
12x
Objects appear twelve times closer.
While higher magnification allows you to see more detail at longer distances, it also comes with trade-offs.
Higher magnification generally results in:
- More image shake
- Narrower field of view
- Harder tracking of moving subjects
- Greater fatigue during extended use
For most users, increasing magnification beyond what is necessary often reduces the overall viewing experience.
The Second Number: Objective Lens Diameter – better known as your Field of View
The second number refers to the diameter of the front lenses, measured in millimetres.
For example:
8x42 = 42mm objective lens
10x42 = 42mm objective lens
12x50 = 50mm objective lens
Larger objective lenses collect more light.
This generally provides:
- Brighter images
- Better performance in low-light conditions
- Improved detail at dawn and dusk
However, larger lenses also make binoculars:
- Heavier
- Bulkier
- More expensive
The key is balancing brightness with portability.
Which Magnification Should You Choose?
8x Binoculars
Ideal for:
- Birding
- Woodland environments
- General wildlife viewing
- Travel
- Marine use
Advantages:
- Very steady image
- Wide field of view
- Easier to locate moving birds
- Less eye strain
Potential limitations:
- Slightly less reach than higher magnifications.
10x Binoculars
Ideal for:
- Hunting
- General safari
- Open landscapes
- Wildlife observation
Advantages:
- Excellent balance between reach and stability
- Versatile for most outdoor activities
- One of the most popular configurations worldwide
Potential limitations:
- Slightly more image movement than 8x.
12x Binoculars
Ideal for:
- Long-distance observation
- Mountain environments
- Open plains
- Professional wildlife observation
Advantages:
- Excellent detail at greater distances
Potential limitations:
- Requires steadier hands
- Narrower field of view
- Heavier
- Often benefits from tripod use
Field of View
Field of view refers to how much of the landscape you can see through the binoculars at once.
A wider field of view makes it easier to:
- Locate wildlife
- Follow birds in flight
- Track moving animals
Generally speaking:
Lower magnification provides a wider field of view.
Higher magnification provides a narrower field of view.
This is one reason why many birdwatchers prefer 8x binoculars.
Weight Matters More Than Most People Think
Many buyers overlook weight.
A binocular may feel comfortable for five minutes inside a shop.
Carry it around your neck for six hours, however, and you'll quickly appreciate the value of lighter equipment.
If you're:
- Walking long distances
- Hiking
- Birding all day
- Travelling
Weight becomes extremely important.
Premium binoculars often reduce weight without sacrificing performance through advanced materials such as magnesium alloy.
Low-Light Performance
Many memorable wildlife sightings occur:
- Early morning
- Late afternoon
- Around sunset
These are also the most challenging lighting conditions.
A binocular's low-light performance depends on several factors:
- Lens size
- Glass quality
- Lens coatings
- Optical design
Two binoculars with the same magnification may perform very differently in fading light.
Higher-quality optics generally deliver brighter images, better colour accuracy, and improved contrast when light levels drop.
Lens Coatings
Every air-to-glass surface reflects a small amount of light.
Without coatings, valuable light is lost before it reaches your eyes.
Modern premium binoculars use advanced multi-layer coatings that:
- Increase light transmission
- Improve colour accuracy
- Reduce glare
- Increase image contrast
Good coatings often make a more noticeable difference than increasing magnification.
Glass Quality
Not all glass is created equal.
Premium binoculars use exceptionally high-quality optical glass that produces:
- Sharper images
- Better colour reproduction
- Higher contrast
- Less chromatic aberration (colour fringing)
While this contributes to a higher purchase price, it also significantly improves the viewing experience.
Waterproof and Fogproof Construction
Outdoor equipment should be designed for outdoor conditions.
Quality binoculars are typically:
Waterproof
Nitrogen or argon purged
Fogproof
This prevents internal condensation when moving between different temperatures or during wet weather.
Eye Relief
If you wear glasses, eye relief becomes very important.
Longer eye relief allows you to comfortably see the full image while wearing spectacles.
Many premium binoculars include adjustable eyecups that accommodate both glasses wearers and those without glasses.

The answer depends on how often you use them.
Premium binoculars generally provide:
- Better image quality
- Better low-light performance
- Superior durability
- More comfortable viewing
- Longer warranties
- Greater long-term value
For someone who spends significant time outdoors, these improvements become very noticeable over years of use.
Common Buying Mistakes
Avoid these common mistakes:
Buying the highest magnification available.
Ignoring weight.
Choosing based only on price.
Overlooking warranty and after-sales support.
Buying without considering your intended application.
Not trying the binoculars before purchasing when possible.
Final Thoughts
The best binocular isn't necessarily the most powerful or the most expensive.
It's the binocular that suits your needs, your environment, and the way you enjoy the outdoors.
By understanding the basics of magnification, objective lens size, field of view, weight, optical quality, and intended use, you'll be able to choose a binocular that provides years of reliable performance and memorable experiences.
