What Binocular Magnification Is Best for Birding? – In-Depth Guide with FAQs

What binocular magnification is best for birding is what we are going to talk about in this article.

Let’s get started!

What Binocular Magnification Is Best for Birding?

Binoculars are categorized by sets of numbers such as 7×35, 8×42,10×50, etc. 7X and 8X are better for beginners. More details make it easier to see the birds.

A 10x binocular offers more magnification than an 8x binocular. However, there is no real advantage in having a higher-power lens.

A pair of 8x binoculars will provide you with the most value for your money. You should avoid buying cheap 10x binoculars.

Why Not Get The Highest Magnification?

Binoculars with high magnifications are better than low ones. A wide FOV allows you to see more.

Higher magnifications allow you to see more detail. A wider field of view allows you to see more of your surroundings. With a larger field of view, you may be able to spot a bird or follow it as it moves around in the trees.

A smaller field of view means less detail. However, this advantage comes with a trade-off. You get a brighter image, but it may be too bright for your eyes.

Buying Guide for Binoculars

Binoculars have become much more affordable than they used to be. You don’t need to spend as much money on them anymore. However, there are still some rules to follow when buying binoculars.

  • the objective lens size must be at least 40mm.
  • the magnification power of your binoculars should be at least 10x.
  • A 30mm lens is the smallest any birder would want to go.

Lens Size

Birders should use 8×40 or 8×42 binoculars. Smaller binoculars are more convenient to carry around. Binoculars with larger lenses are brighter and offer wider fields of view.

A higher-quality lens will give you a clearer picture. You’ll need more money to buy a bigger lens.

Objective Lens

A bigger objective lens will give you better results than a smaller one. You’ll be able to see more details when the light levels drop, and therefore, more opportunities to view birds.

Exit Pupil

So a pair of 10x 50s would have an exit pupil size of 5mm (5/10 0.5), and 8x 32s would have an exit pupil size of 4mm (4/8 0.5).

You can see this beam of light when you hold up binoculars (eyecups towards you). It appears in each eyepiece as a tiny circle of bright light.

Adjustable Focus Lens

Binoculars have an adjustable focus lens that allows you to zoom in or out to get closer or further away from objects.


When you use binoculars, the size of the object you’re looking at determines how much magnification you need. The larger the object, the more magnification you need. In this case, the object is the Exit moon.

Close Focus

Close focus is the shortest distance between your eye and the lens of the binocular. Binoculars are designed to give you a clear view of objects at a short distance.

At closer distances, the image gets smaller and harder to see. You may need to adjust your binoculars’ focus to get a clearer picture.


Binoculars are expensive because of the quality of the lenses.

  • The more expensive ones have better optics than the cheaper ones.
  • A cheap pair of binoculars may have a smaller field of view but they won’t be as sharp or clear.
  • Cheap binoculars usually have plastic lenses, while expensive ones use prisms.

Should I Choose 10×50 Bird-Watching Binoculars?

For your first pair, we recommend 10×50 binoculars that will work well for most birding habitats including coastal areas, marshes, and open fields.

What Are the Best Size Binoculars for Bird Watching?

Binoculars are useful tools for bird watching. A beginner should start out with an 8×42 binocular. This gives you enough magnification to identify birds but also allows you to see them in more detail.

You’ll be able to spot details such as feathers, beaks, legs, tails, etc. An 8×42 binocular is also great because it’s compact and lightweight.


Bird-watching binoculars are great for beginners. They come with waterproof, shockproof, multi-coated ED glass lenses. They also have no batteries, and adjustable, easy-to-clean designs.
