What are the best binoculars for bird watching?

In birdwatching, 8x42 is seen as the gold standard. The 8x gives a good level of magnification, and the 42mm provides a wide field of view whilst also providing a bright image. 8x42 is ideal for if you’re hoping to spot a fast-moving bird in a good level of detail. Binoculars with a lower magnification are also much easier to hold steady, which is a must unless you rest your binoculars on a support or choose a pair with image stabilisation.

The Swarovski Optik 8x42 NL Pure and ZEISS Victory SF 8x42 T* Binoculars are seen as two of the best options for professionals and seasoned birders, whilst binoculars like the Hawke Vantage 8x42 and Nikon Prostaff P3 8x42 are good options for beginners. For something in between, look towards the Vortex Diamondback HD 8x42 or the Nikon Monarch M7 8x42 Binoculars.

What do the numbers on binoculars mean?

Typically, there are two numbers on a pair of binoculars. The first number is the magnification and the second is the diameter of the front glass (objective lens) in millimetres.

The magnification will typically be 8x or 10x, but other levels of magnification can also be seen such as 4x, 7x and 12x. And for the objective lens, the higher the number means brighter images with a wider field of view, but will also mean the binoculars are bigger and heavier.

By dividing the second number by the first will give you the light gathering power, so for example the Swarovski Optik 10x42 TA Binoculars give you a light factor of 4.2.

Which binocular magnification is better?

There are two popular binocular magnifications, with 8x widely considered to be the best all-rounder, whilst 10x is also popular and a versatile choice.

An 8x magnification means an object that is 800m metres away looks 100 metres away, and the 8x offers a wider field of view, is easier to hold steady and has a brighter image. It’s ideal for woodland birding and general hiking, and is also the choice preferred by beginners.

The 10x magnification brings the subject closer (compared to the 8x, an object 800 metres away now looks 80 metres away) and provides greater detail. Because the image is magnified more, it provides a narrower field of view and also requires a steadier hand. It’s an option preferred by more experienced binoculars users, and is ideal for stargazing, safaris and open-country wildlife viewing.

Other options you may see include 4x and 7x on more compact models, and 12x and above, which are great for long-range observation but will require a tripod or rest to produce a steady image.
