What are 10×42 Binoculars?

10×42 is the optical configuration of a pair of binoculars. The two numbers represent two separate performance measures. The first number is the magnification power and the second refers is the objective lens diameter.

Best 10x42 Binoculars

This means that in a 10×42 binocular, ten refers to 10 times magnification power i.e. the binoculars can make the image appear ten times larger than its actual size.

The second number 42 refers to the diameter of an objective lens which is an essential parameter in determining the amount of light that is allowed to pass through the lens and enter your eyes.

The 10×42 configuration of a binocular is sometimes considered to be the universal configuration because it is practical and adequate for all types of situations.

What to look for in Binoculars

There are certain concepts that act as the factors which you need to consider before choosing the best 10×42 binoculars for your conditions.


Magnification power of a binocular decides the extent to which an image can be zoomed or magnified by it. Higher magnification means that you can focus on distant objects more clearly. But the level of magnification achieved by a pair of binoculars can affect its light gathering and retention capabilities. This means the more the magnification, the less is the brightness of the image. Therefore, you need to maintain a balance between magnification and brightness. 

Objective Lens Diameter

The objective lens diameter or width determines the light transmission and retention rates of a pair of binoculars. The greater the size of the objective lens, the wider will be the field of view. The brightness also increases with the increase in field of view. This will eventually increase the overall brightness and clarity of the image.

Visual Clarity

One yearns for a crystal clear image when using any optical gear. The optical clarity and quality of the images produced by a pair of binoculars are among the most important factors you’ll have to consider before purchasing them. If a pair of binoculars possesses the ability to make you feel that you are viewing the object in real without an aide then, such a binocular is a must have.

Low Light Performance

On any kind of outdoor excursions, there is a high chance that you encounter a situation where you wish to capture stunning visuals in low light conditions. This may not be possible with binoculars that cannot perform well in poor lighting and you will eventually be left abandoned in capturing some of the rarest moments you will ever see. Make sure to buy binoculars that allow you to observe and focus on subjects even in poorly lit surroundings and have the ability to magnify not only the image but the brightness as well.

Overall Optical Quality

The overall optical quality is a very crucial factor that you need to consider before deciding on a pair of binoculars. One needs to ensure that the binoculars employ lenses made out of best quality glass if they wish to observe breathtaking views. The optical quality of a component used in a binocular refers to the clarity of glass used and how well the surface of the lens has been polished. Better optical quality ensures a reduced amount of reflection or dispersion of light.

Lens Coating

A lens must have an appropriate coating to enhance its performance. It is very important to have your lens coated properly to get rid of its irregularities and protect it from dust and scratches. This will help prevent the diffraction, distortion and spreading of light. Also, another kind of coating known as an anti-reflective coating may be used to reduce the reflection of the lens surface. A lens coating also tends to smoothen the surface of the lens and make it easier to clean.

Exit Pupil

Exit pupil is simply a window which allows the light to enter and pass through the binoculars. Just like we have pupils to allow the light to enter our eyes, binoculars possess pupils too. The larger the size of the exit pupil, the more light is allowed to pass through the binoculars. This results in a much brighter view.

Field of View

The area of vision which a pair of binoculars can provide at 1000 yards with utmost clarity is defined to be the Field of view of the binocular. For example, a field of view of 329 feet means you will be able to clearly see an area of 329 feet, a 1000 yards away from you.

Close Focus

Close focus refers to the amount of focus you can achieve on an object using a pair of binoculars. It depends not only on the binocular but also on the viewer’s eye and focusing ability.

Prism type

There are two main categories of prisms used in binoculars: Porro prism and Roof prism. Among these, the Roof prism is considered to be of great use. It is lightweight and slim in design and dimensions, as it is in a direct line with the eyepiece. And the best part is its reflecting power is which can reflect the transmitted light five times. Speaking of the Porro prism, it requires a larger body to assist itself with the reflection of light. The biggest drawback of this prism is that it isn’t placed in direct alignment with the eyepiece, due to which the actual position of the object gets misplaced. Porro prism binoculars are only recommended for people on a tight budget.

Eye relief

This is a very crucial element of a binocular, especially for those who wear glasses. Eye relief is the distance at which you can hold the binocular from your eye and still be able to see a clear-cut picture. It is recommended that people with glasses should opt for binoculars with an eye relief of 14 to 15 mm.

Additional features

It is pretty essential for a pair of binoculars to be waterproof, fog proof and dust proof since they are categorized as outdoor gear. This will allow you to continue using binoculars even under the harshest weather conditions and still observe your target.
