Buyer’s Guide to Binoculars

Types of Binoculars

There are many different types of binoculars to choose from nowadays and knowing which ones will help you in different situations is also useful to know.

  • Night vision binoculars – A standard pair of binoculars are going to be next to useless for you if you are needing them at night. In these cases, you may want to consider a pair of night vision binoculars that are electronically assisted optics that take the little available light you have and amplify it through a series of photon-enhancing components.
  • Marine and waterproof binoculars – A pair of marine binoculars are specifically designed to be in and around water. They have a wider ocular and objective lens with low to moderate magnification power. When on the high seas you are going to want something that has a larger field of view with a lower magnification, as too high of magnification will cause a shaky image with just the slightest hand movement. Marine binoculars are also generally fog and waterproof.
  • Budget binoculars – You can find several types of budget binos on the market if you don’t have deep pockets. A pair of Nikon Aculon A211 10×50 suit a wide range of purposes, from birding to travel and sporting events, and are lightweight enough to bring along for the day and come with a relatively small price tag.
  • Premium binoculars – when it comes to expensive but quality binos, you would be looking around at Zeiss as they make some of the best binoculars around. With amazing quality and optimized objective lens diameter, they usually come with some fantastic features likes smooth focusing mechanics, crystal clear images with the fully coated lenses and fashionable designs. Or you can go for Swarovski. Just like the Zeiss models, the Swarovski binos have similar feature and can cost you a few thousand for a pair of these.

Field of View

When it comes to viewing your field. Most models of binoculars have a wide viewing range. Real field of view is the angle of the visible field, seen without moving the binoculars, measured from the central point of the objective lens. The larger the value is, the wider the view field available. For example, binoculars with a wider field of view such as 8×42 are advantageous for locating fast moving wild birds within the view field.

Take the Nikon 10×50 model. The first digit 8 is the magnification, which means how much times closer you are to the object and the second digits 50 is your viewing field, which means how much of the area you can see through looking into the binoculars.


Sizes and weights will vary depending on model and magnification and the viewing field. The construction of models will depend on whether they are light weight or on the bulky side, they can be made of aluminum, which makes them hard and more cumbersome to carry. Other materials used to make them include leather or neoprene. Most cases include a practical strap for a more comfortable carrying. In other cases, they are built for a specific type and size of binoculars.

In general the lower the magnification and better construction used to make them, the lighter they will be. Take the celestron nature or the Nikon monarch for example, super lightweight weighing less than 500g.

Extra Features

Lens sizes – When it comes to lens size, the choice is clear: think of what is the activity you will be performing the most. If your use for binoculars will be astronomy, a larger objectives lens size and even a larger magnification works great.

Magnification – The most common magnifications for binoculars are 5x, 7x, 8x, 10x and 12x. The lower the magnification the further you will see the objects that are far away.

Prisms – A prism is a sectioned block of glass that reflects light. The prism is important when it comes to size since it folds the path of light, allowing the size of the binoculars to be much smaller than a telescope. There are two types of prism that are most commonly used today, BAK-4 and BAK-7. The BAK-7 is used in cheaper models due to its low price and the fact that they are made of less dense glass. BAK-4 are denser and transmit more light and usually come in more complex models.


1. Which is the Best Magnification for Binoculars?

The best magnification will depend on what you are using the binoculars for. For bird watching for example most birders suggest that a magnification of 8x is more adequate for viewing birds as our hands shake and it is very difficult to keep steady hands when viewing objects move in the air.

The binocular’s magnification increases not only the size of the image, but also the apparent shakiness. So the more you magnify, the more the image is jumping around. At some point, the advantage that comes from making the image larger just gets overwhelmed by the unsteadiness of the hand. That is why many people find that they will actually see just as much detail or more with the 8x magnification.

For astronomy binoculars, most people consider 15x magnification to be the best because you get to see the stars 15 times closer. It also worth noting that using a tripod for your binoculars will make your view more steady when star gazing.

2. What is Better 8×42 or 10×42 Binoculars?

Taking into consideration that the difference between the 8x magnification and the 10x magnification is purely how close to the object you are viewing is, but with that in mind any movement that you make gets multiplied by the magnification and thus you also get more image shake with a 10×42 vs 8×42 when hand holding them and thus even though the image may have more detail if it is shaking about too much you won’t be able to appreciate it.

In good to average light condition, it is often impossible to notice a difference in brightness between the views of equal quality 8×42 and 10×42 binoculars. But in forest light the pupils in your eye expands to allow them to take in more light, the larger exit pupils created by the 8×42 configuration is a definite advantage and means they will often look to have a brighter image than the 10×42 equivalent.

As for pricing, as standard the bigger the number, the bigger the price will be. All in all for sporting events or star gazing you would consider 10×42 for getting closer to the action, but for birders then you would probably choose the 8×42.

3. What is Better 10×50 or 10×42 Binoculars?

To be honest there is not a great difference between 10×50 and 10×42. The main difference is that the 50mm lenses are 8mm bigger in diameter than 42mm ones and thus the ends of the barrels where the objective lenses are set, reflect this difference by about the same amount. As you move down towards the ocular lenses, they taper down in size as most 10×50 binoculars will incorporate the same eyepieces as that of the 42mm versions.

Another difference is the light that is better with the 50mm as of course it is slightly wider, the larger surface area of 50mm lenses means that they have the potential to capture more light when viewing than 42mm ones. The 50mm has a larger Exit Pupil which makes it easier for you to line your eye up with the light exiting the eyepieces and thus a 10×50 binoculars is simpler to use because it is easier to achieve an image without black rings on the edges of the view.

Taking everything into account, the 10×50 is gonna be slightly more expensive than the 10×42 because of the larger body and bigger eye glass, but for viewing the 10×50 binoculars are better.
