Best 10x50 Binoculars

What Does 10×50 Mean?

People often get confused by the two numbers used to describe binoculars, but they have a relatively simple explanation. The first number, 10, is the magnification. Looking through 10×50 binoculars, objects will appear ten times closer than with the naked eye.

The higher the magnification, the closer the image will appear compared to the naked eye.

The second number, 50, refers to the size of the objective lens, measured in millimeters. The objective lens is the larger one farthest from your eyes.

Larger objective lenses are best for low light conditions as they gather more light. Therefore, they are perfect for evening wildlife viewing and amateur stargazing.

However, a larger objective lens adds to the overall size and weight, and significantly increases the price.

What to Consider When Choosing 10×50 Binoculars

Before buying your 10×50 binoculars, there are several factors to consider to find the best product for your needs.

Lens Material

The lenses made for binoculars are usually glass, but plastic lenses are also available. Binoculars with plastic lenses are often cheaper, and as expected, do not offer the same quality of optics.

Plastic lenses are more durable and can handle falls better. We recommend plastic lenses for novice users and children.

Lens Coating

The lens coating reduces the amount of light reflected while allowing the maximum amount of light to go through the lens. Coated lenses transmit more light, offer more clarity and sharper images overall.

The overall quality of the lens ensures the image viewed is aberration-free and has a sharp contrast. Cheaper binoculars can lose over 30% of light before the image reaches your eye.

A superb quality lens works better in low light conditions, transmitting more light. It also ensures the colors are vibrant and not distorted.

There are several types of coatings available, and the type used on the lenses will normally be reflected in the price of the binoculars.

  • Coated: If it just says ‘coated,’ it means that there is just one anti-reflective coating on at least one lens.
  • Fully coated: This means that the coating is on the ocular lens, objective lens, and prism.
  • Multi-coated: Multi-coated means that there are multiple layers on at least one lens.
  • Fully multi-coated: For this, every surface, the objective lens, ocular lens, and prism have multiple coatings, which is a sign of the highest quality of binoculars.
Photographers and Beginners

Exit Pupil

When you point a pair of binoculars out a window during the day, you will see a little circle of light, thanks to the exit pupil. Better put, the exit pupil is the tiny hole in the ocular that allows you to see images.

A higher number for the exit pupil means more light gets to your eye, especially in low light situations. It also means it will be easier to maintain a full, crisp image of your object regardless of whether your hands move or shake.

To calculate the exit pupil size, you divide the diameter of the objective lens by the magnification number. Given your binoculars are 10×50, 50 divided by 10 would equal an exit pupil diameter of 5mm. Therefore, the 10×50 binoculars would be perfect for low-light situations like dawn and dusk.

Field of View

The field of view is a pretty simple factor to keep in mind because it tells you the width you can see when the binoculars are not zoomed.

If a binoculars’ field of view is 450 yards it means that, at 1,000 yards from where you are viewing, the image you can see through the binoculars measures 450 yards edge to edge.

So, for example, if you want to go bird watching, a wide field of view is best to scope out the landscape better.

The smaller your field of view, the harder it is to follow your subject of interest, say wild game.

A small field of view also means that much less light gets in; thus, the images can be slightly dark.

Eye Relief

This is the amount of distance between your eye and the eyepiece that allows you to see the whole field of view offered by your binoculars without the image vignetting. Eye relief is mainly an issue for spectacle wearers.

Today, most manufacturers accommodate people wearing glasses by providing retractable eyecups. If you wear glasses, our recommendation would be to adjust eyecups to the minimum position to provide enough eye relief.

Using binoculars with an eye relief lower than 10mm, you can only see the center of the image. Most binoculars have an eye relief of 8-13mm. But newer LE models offer eye relief of up to 18mm, and this can make all the difference for people who wear glasses.


Binocular sizes are often broken down into compact, mid-size, and full-size categories based solely on the size of their objective lenses.

It is also essential to note that though binoculars are categorized by size, variations in design and construction mean that similarly sized pairs are likely to differ in weight.

  • Compact binoculars: The objective lens size is less than 30mm (10×28, 8×25).
  • Mid-size binoculars: The objective lens size is between 30mm and 40mm (8×32, 10×30).
  • Full-size binoculars: The objective lens size is greater than 40mm (10×50, 8×42).

Full-size binoculars may be heavy and uncomfortable to hold over long periods, while mid-size and compact binoculars are the best for prolonged use.

Prism Glass

There are two types of prism in binoculars: Bak-4 and BK7. These terms refer to the types of glass used in the lenses. Bak-4 is a superior, high-density glass and is considered better quality than BK7 while costing much more.

If you are interested in bird watching or hunting, you should consider Bak-4. The antireflective properties give clearer images, thanks to their ability to transmit more light.

For casual use, on the other hand, you can go for BK7. It is a low-density glass that produces lower-quality images than BAK-4, especially in low light.

Types of 10×50 Binoculars

Porro Prism

The most common 10×50 binoculars are ones with a Porro Prism inside. This prism has the glass elements offset from each other which gives you a better depth of field and a brighter image, as it allows more light to filter through the glass.

Roof Prism

These types of 10×50 binoculars are far narrower and usually less robust than ones with Porro prisms.  Roof prism binoculars are more streamlined and easier to grip since the glass elements are aligned.

This design is more expensive than the Porro prism.

Benefits of Using 10×50 Binoculars

  • Bright images: One of the benefits of the 10×50 binoculars is that they brighten an image seen through its lens. Larger lenses and Porro Prism binoculars filter in more light.
  • Detailed images: When using the 10×50 binoculars, you can view the image in tremendous detail. For instance, you can see a bird perched up a tree with the naked eye, but with the best 10×50 binoculars, you see individual feathers and patterns that you may not have noticed.
  • Distanced viewing: The main aim of the 10×50 binoculars is to provide a better image from a distance than you would with your naked eye. The binocular lens helps you focus and see as far as 12 miles away compared to the human eye than can see up to 3 miles on a good day.

Frequently Asked Questions

Do I Need to Take My Binoculars Apart to Clean Them?

No! Binoculars are precision instruments that are finely aligned and may also be hermetically sealed to contain anti-fogging gas. Opening them for cleaning or repair should only be performed by a professional.

If you have a large pair of binoculars, then yes, you may need to purchase a tripod. Also, if you intend to use them for astronomy, a tripod would be necessary to enjoy a more steady view.

We highly recommend binoculars with an objective lens of up to 50mm and a magnification of about 16x. Buy lightweight binoculars as they are comfortable and offer a steady view without straining your hands.
