Binoculars Buying Guide

How to Pick the Right Binoculars

To the untrained eye, one set of binoculars resembles the other. Some are smaller than others, but they’re always built up of a pair of barrels with lenses on one end and a hinge in the middle that connects them.

If you dig a little deeper, you’ll find a slew of features and characteristics that decide how good a pair of binoculars is and what activities they’re best for.

What are the best binoculars to buy?

If you’ve ever looked for or used a pair of binoculars, you’ve probably noticed that they all have a set of numbers written on them, such as 8×42 or 10×25.

The magnification level is specified by the first number. A pair of 8x lenses will magnify your subject by eight times, while a set of 10x lenses will magnify it by ten times. In millimetres, the second number indicates the size of the objective lenses (the huge ones at the end).


The magnification level is the most crucial number to consider. Isn’t it true that more is better in this case? That isn’t entirely correct, though. While a 10x or 12x magnification allows you to view things that are further away a little closer, higher magnification has side effects.

Holding binoculars steady enough to see a stable image becomes difficult at greater magnification levels. A narrower field of view is often associated with increased magnification. Another figure on the binocular is the field of vision (or FOV). When you peer through them, it’s usually represented in degrees and relates to how much you can see from left to right.

For bird watching, what is the optimal magnification level?

8x binoculars are ideal for birdwatching and wildlife observation. This gives you a wide field of view (typically around seven to eight degrees) and magnification, as well as allowing you to handle them comfortably without distracting vibration.

You’ll want a greater magnification level – 12x and up – if you’re more of a stargazer and need binoculars for staring at the moon and constellations, but you’ll need to consider using a tripod.

What are the advantages of purchasing larger-lens binoculars?

When it comes to the quality of the image you view via your binoculars, the size of the objective lens is most important. The stronger the lens’ light-gathering power, the larger it is. The image will be foggy and dim if the binoculars are too small; yet, if they are too huge, they will be too unwieldy and heavy to use.

Because they strike the ideal combination between light gathering and practicality, we’ve largely concentrated on binoculars with 42mm objective lenses (as do most manufacturers). Choose a set with 25mm or 32mm lenses if you want pocketable binoculars.

You can get away with larger lenses if you’re mostly going to be stargazing or installing your binoculars on a tripod. In summary, an 8×42 pair of binoculars amplifies a scene by 8 times and has 42mm lenses, whilst a 10×25 pair has 10x magnification and 25mm lenses.

Should I be concerned with details like prism kinds or ED glass?

Porro prism, roof prism, and ED glass are some other words associated with binoculars that you may hear and see on specifications sheets.

Prisms are used in all binoculars to keep the size down; otherwise, they’d all be big and appear like a pair of telescopes strapped together. Porro and roof prisms are used in all binoculars. Prisms, on the other hand, come in a variety of shapes and sizes, and the sort of prisms you employ determines the shape and size of your binoculars. Porro prisms are commonly used in A-shaped binoculars.

Roof-prism binoculars are larger and thicker, although Porro prism binoculars are slightly less expensive. Roof prisms are used in newer H-shaped binoculars. Because they are smaller and lighter than Porro-prism optics, they are the most prevalent variety in use today.

ED (extra low dispersion) glass (also known as HD glass by some manufacturers) is a specific form of glass that is meant to reduce chromatic aberrations. A black item silhouetted against a bright background, such as a kestrel against the sky, can be used to detect chromatic aberrations.

Color fringing appears around certain things as a result of it. Binoculars with ED or HD glass tend to have less fringing, resulting in a clearer and sharper image. However, because ED glass is more expensive than ordinary glass, you’ll only find it in binoculars that cost more than £200.

Other important characteristics to keep an eye on include:

Close focus: Ideal for observing insects and examining flowers up close. You can concentrate from as near as 1.5 metres away with the best binoculars.

Waterproofing: You’ll be using your binoculars outside, so be sure they won’t leak if it rains. If this happens, the inside surfaces will fog up and condensation will accumulate.

Manufacturers fill their binoculars with an inert gas (typically argon or nitrogen) that has no water content and thus inhibits condensation, to minimise fogging when transitioning from the cold outdoors to the warm interiors.

If you wear glasses, binoculars with a lengthy eye relief and adjustable eyecups will make seeing the entire field of view much easier. Binoculars with a 14mm or longer eye relief are ideal. However, the more you have, the better, because you’ll have more chances to fine-tune your view.
