Binoculars can serve a purpose in different activities, from our hobbies to professional work.

Now, depending on our specific purposes, different binoculars are suitable for us. 10×42 and 10×50 binoculars are quite the hot topic now. So, which one is better? What are their differences?

Well, the answer lies in the numbers. The first number (10) refers to the magnification power, while the second number (42 or 50) refers to the size of the objective lens.

Our 10×42 vs. 10×50 Binoculars comparison guide will go into the details of what sets them apart. So, read on to learn which one is a better choice for you.


The Thing About Binoculars – What Do the Numbers Mean?

Binoculars are basically two telescopes based on one platform that allows both the eyes to view an object from afar together. Like any other technical tool, binoculars also have some specifications. Let us talk about the number that describes the specification of binoculars and what they mean.

10×42 vs. 10×50 Binoculars | Which One Is Better?

  • Magnification of the Binoculars

In the number 10×42, 10 means the binocular’s magnification is 10 times. Yes, that means in binocular size specifications, the first number is always the magnification.

The bigger the number, the bigger the image you will see through the glasses. Whether or not you need specifically larger or smaller magnification depends on your use.


  • The Objective Lens 

When we are talking about a 10×42 binocular, the second number indicates the objective lens size in mm. It means a 10×42 binocular has a lens size of 42mm each. These lenses capture the light from the object and take it to the next step. So, the lens is an important factor.


The Different Uses of Binoculars 

Binoculars are used in many activities. Starting with things like wildlife viewing, hunting, hiking, and stargazing. And to events like gold, sports events, nighttime viewing, marine activities, etc., different types of binoculars exist for these purposes. The sizes, weights, and specifications for all of these may differ.


About 10×42 Binoculars 

10×42 binoculars have a magnification of 10x, and the size of the diameter of the lenses is 42mm. For outdoor or wildlife-related activities, 10×42 binoculars are a great choice. The 42mm objective lens provides a bright image of the object, and the 10x magnification provides a standard, clear view of the object.

People mostly prefer these 10×42 binoculars for watching outdoor activities like concerts, sports events, hunting, wildlife viewing, or bird watching. These binoculars are a pretty popular option as it is cheaper, easy to carry around, and great for normal use.


About 10×50 Binoculars 

10×50 binoculars have 10x magnification and 50mm diameter of the lens. While the magnification is the same as the previous one, the diameter of this is slightly bigger. The overall shape and weight of 10×50 binoculars are bigger too.

Now, the difference that comes due to the 50mm objective lens is that due to the bigger lens size, it can capture more light. As a result, it helps with viewing images even during low-light situations.

The price of the 10×50 lenses is slightly high too. This binocular can be used almost the same as 10×42 ones. So, where’s the big difference? 10×50 binoculars can also provide clear visions during night times, or at least in very low light conditions. This allows you to observe things from very far away, even at night.
