Are 10×42 binoculars good for bird watching?

In short

10×42 binoculars are a good choice for birding. You will get a higher magnification balancing with the aperture, eye relief as well as a wider field of view. At the same time, you will be able to watch mid to long-distance birds by these specifications.

In-depth

When you pick a binocular for birding, you should be concerned about the overall specifications as birds usually live far away from human beings. They move frequently here and there. So watching open countryside birds or ducks, shorebirds and hawks, 10×42 is one of the best options for you. Now let’s reveal the features and specifications that generally a 10×42 binocular will provide to enjoy birding perfectly.

Magnification

When you choose a binocular, magnification is the main concern for all of us. To see any distant objects like birds, higher magnification is required. Among various specifications, 10x can enlarge the birds 10 times closer to you. As a result, you can see them clearly with all details. As birds are smaller in size mostly, 10x magnifying binoculars will satisfy you with the large-scale view. Most of us are only concerned about the magnification of the binoculars, but there are many factors you should consider before choosing birding binoculars. Otherwise, you won’t get outstanding performance and high-resolution images while watching birds.

Aperture

There are 2 prominent values in the binocular – 10×42. Here the 42 is the aperture value which means the diameter of the objective lens is 42mm. The bigger diameter ensures more lights can come through it to your eyes and produce brighter images. The 42mm width of the objective lens is a decent size to render clear and bright images of the targeted birds. Birds start flying in the early morning in search of food. Though the sunlight is less in the early morning.

Similarly, they came to their nest drawing sunset. With a larger objective lens, the lights will be controlled and ensure maximum light gathering. You can watch birds clearly during these times even in low light conditions. When you go bird watching, you can see them perfectly with the 10×42 binoculars.

Field of view

The field of view is the area you can see at a time using a binocular. Field of view has a direct relationship with the magnification power. The more magnified, the binoculars will provide a smaller field of view. For bird watching, 330 feet per 1000 yards is considered perfect. Or 6.3 degrees of arc is also considerable. In this case, most of the 10×42 binoculars provide a 300 to 375 feet field of view at 1000 yards. So you can see a large area at a time by this specification.

Exit pupil and eye relief

Exit pupil and eye relief both are interrelated to our viewing comfort. As we have no control over the activities of the birds. We need to hold and observe their movements for a certain period. Viewing comfort is very important. But how can you determine if your selected pair is good for smooth viewing or not? The answer is simple and easy. You should know the values of eye relief and exit pupils. For 10×42 binoculars, the exit pupil value is constant and the value is 42/10=4.2 mm.

An exit pupil value of more than 4 mm is regarded as perfect for comfortable viewing. The eye relief values should be between 5 mm to 23 mm for non-glass wearers. For glass wearers, it should be more than 16mm. You should choose a good brand’s 10×42 binoculars. Thus you will get a decent number of eye relief values which will be suitable for both eyeglass wearers as well as non-wearers.

Focus

Some of the birds love to move to the roadside, in front of our houses, or on lakes. Some live far away from the human touch. At the same time, all of the birds often move here and there habitually. The focus is a crucial factor before choosing a binocular for birding. Typically 10×42 binoculars provide a central focus knob to adjust the focus quickly. Some of them have a close focusing system to focus on the nearest birds. 10×42 binoculars are up to the mark for focusing purposes too.

Prism

Binoculars come with 2 types of prism attachments. This is the same for 10×42 binoculars also. Prism types vary according to the brands and other factors. Usually, roof and Porro prisms are used to make binoculars. The Porro prism binoculars perform too well but the size is slightly bulky. On the other hand, roof prism attachment makes the binocular compact and lightweight. For birding, a 10×42 roof prism binocular will be more suitable.

Withstand Capacity

A good binocular has water, fog and dust withstand capacity. 10×42 binoculars are mostly waterproof and fog proof. You can watch birds in the open countryside as well as from your house too.

Weight

To enjoy birding, you should always prefer lightweight binoculars. As you need to hold them (if the tripod adapter is not set) for a longer period, you should choose a lighter pair. Most of the 10×42 roof binoculars weigh less than 1 pound. It is compact and quite easy to hold as well as move.

Price range

The price range varies according to the manufacturers as well as other features. Most of birding binoculars are plastic and rubber armor made to keep them lightweight. In that case, you will get birding binoculars from $40 to $500. It’s a good deal to get a quality binocular with 10x magnification in an affordable price range. You can go for the high-end too based on your budget and preferences.
