What is Magnification?

Ask yourself this: why do we buy binoculars? The answer is obvious, to see things that are far away and cannot be seen by the naked eye.

In other words, binoculars are tools that are used to magnify an image or scene so that we can see it up close. That is, without a doubt, the main function of binoculars.

How Does Magnification Work?

You already know that most binoculars include their magnification number in their name on the back of the lens.

Often you will see a binocular name followed by some number like 10×42 or 8×40.

The number that comes before x simply means that an image viewed through those binoculars will appear magnified according to that number.

So what does a 10×42 mean in binoculars?

10×42 simply means that a picture seen through the binocular lens will appear 10 times more magnified or near than original naked eye image.

Let me quote an example to make it easy for you.

If you are viewing an image that is 1000 yards away than by using 10×42 binocular that image is going to appear only 100 yards away.

Now that is something to consider when buying binoculars, isn’t it?

What Does Aperture or Lens Diameter Means and How it Works?

To provide you with a clear and high-quality image, magnification and aperture work together. We cannot focus only on magnification while ignoring the lens diameter.

A bigger binocular will have a bigger lens in diameter. Lens diameter basically allows light to enter in the optical pathway thus creating a bright and clean picture.

There is no rocket science involved to understand that a bigger lens means brighter and more detailed image.

Although other factors such as lens coating, use of different prism and housing material also play a pivotal role in creating a supreme quality picture.

When looking for the answer to what does 10×42 mean in binoculars, we cannot ignore the number that comes after x.

In 10×42 binoculars, the lens diameter will be 42mm. An interesting thing to note here is that while lens diameter plays a big role in determining the weight of binoculars, magnification has little to do with the size of optics.

Field of view is another issue when choosing the right binoculars. Field of view means the area that is being covered when you are using binoculars.

If you own larger lenses that simply means you get to see more area as compared to binocs with smaller lenses.
