  • Field of view - Field of view is important if you want to be using your binoculars for wildlife viewing or bird watching, as it allows you to track your subject in a larger frame without having to zoom out, typically at a spot of 1000 yards away, this should be between 6 and 8 degrees.

When looking at 8x42 binoculars, you might be wondering if 10x42 binos are any better as they have higher magnification and typically comes with the same weight and size. 

We have compared both 8x42 binoculars and 10x42 binoculars down below to help you decide which model is right for you. 

8x42 Binoculars 

These 8x42 binoculars have the same objective lens as 10x42 models, except use a lower level of magnification. Advantages of these binos over the 10x models are their exit pupil which tends to be larger, making it easier to line up your eyes when using the model and producing a brighter image too.

The binoculars additionally will often be a little lighter in weight too and have a larger field of view, allowing you to see more in the frame when at top magnification. As these binos are more popular they will be more affordable too. 

Drawbacks of these binoculars in comparison to 10x42 models will be their lower magnification, meaning you can't see as much detail far away. So if you want to see subjects from a very far distance, 8x binoculars will struggle more with this.


  • More affordable. 
  • Wider field of view. 
  • Lighter in weight. 
  • Brighter image. 


  • Less detailed image when magnified. 

10x42 Binoculars 

For 10x42 binos, they always win over 8x42 models when it comes to long-distance viewing, you will never be able to see the same amount of detail from a long distance with 8x binoculars as you would with 10x binos. 

However, because of this increase magnification they have a smaller field of view too and are more expensive, so might not be the best choice for birding, as you can fit as many subjects in your frame. They further have a smaller exit pupil so aren't the best for viewing in lower-light conditions. 


  • You can see more detailed images. 
  • Allows you to see things further away.


  • More expensive. 
  • A smaller field of view. 
  • Bad performance in low light.

Which Power Binoculars Should I Choose?

Overall, if you are planning to view subjects at mid-distances away and want to use your binoculars for bird or wildlife tracking then an 8x42 pair of binoculars will probably suit you better as they allow you to follow subjects with their wider field of view, they also work well in low light, making them better to use in forests or woodlands. 

On the other hand, if you want to see subjects at long distances then a 10x42 pair of binos might suit you better, especially for sport or astronomy.

How To Use 8x42 Binoculars 

When your first get your binoculars, you will probably be keen to unwrap them straight away and start observing, however, before you do this you need to ensure that they are set up correctly so as you can get the most out of their performance. 

We have put together some basic steps to using your 8x42 binoculars for the first time down below. 

  • Step one - First of all adjust the two barrels of the binoculars so as they can be the right width for your eyes without a black field around the edges of the image.  
  • Step two - Find something to focus on such as a street sign then focus the binoculars with both eyes open by turning the central focus knob.  
  • Step three - To fine focus, close your right eye and use your left eye to adjust the focus until the image you see is clear, after doing this close your left eye and adjust the dioptre until the image is clear again. 
  • Step four - Open both eyes to check if the image is clear, if not then repeat the steps making small adjustments until you see a clear image.

FAQs About The Best 8x42 Binoculars 

How much do 8x42 binoculars tend to cost?

This all comes down to the brand and the specs it comes with, they can cost between a general price range of £100-£400.

Should I clean my binoculars? 

It is important to clean your binos, but not too much, you should always use a microfibre cloth, lens cleaning solution and compressed air to clean your binoculars, never use standard soap or tissue as this will damage the lens.

Do I need a tripod for my 8x42 binoculars? 

No, despite many 8x42 binos coming with tripod adaptability, this is just an extra and you don't need to use it. Tripods are needed for binoculars with a magnification of over 12x as they can become shaky to view when handheld.

Are 8x42 binoculars good for hunting?

Yes, 8x42 binos are great for hunting as they are lightweight which allows you to hold them for long periods and they still keep their wide field of view which is excellent for tracking moving subjects.

What does Bak-4 prism coating mean?

Bak-4 Prism refers to the type of glass used during coating, these are available in different ranks, but in general, it means the lens has a high-quality finish.

Is more or less field of view better on my binoculars? 

More field of view has two disadvantages to consider, one is that it will often mean a smaller eye relief which is not great for glasses wearers, two is that a bigger field of view means less magnification, so it comes down to what you will be using your binoculars for.

For wildlife viewing, you might prefer a bigger field of view, but for astronomy, you want to be able to view images at a far distance with detail.

Should I get 8x42 or 10x42 binoculars for wildlife watching? 

In our opinion, both 10x42 and 8x42 binos are great for wildlife watching, but we tip in favour of the 8x42 models as they have a wider field of view that allows you to track and follow animals.

Are lens coatings on binoculars important? 

Your binoculars need to have lens coatings as this can dramatically improve the image you see through the lens, reducing chromatic aberrations and reflections distorting what you see, the best binos have fully multi-coated lenses.

Do I need binoculars with image stabilisation?

For 8x42 binoculars they do not need to have image stabilisation, as the magnification inside can be handheld without producing a shaking image, image stabilisation becomes useful in binoculars that have a high power over 12x.

Our #1 8x42 Binoculars For The Clearest Image 

Our number one pair of binoculars for creating a high-quality image as well as comfortable viewing is the Opticron Discovery WP PC 8x42 Binoculars thanks to their high-quality multi-coated lenses and long eye relief.
