How to Choose Binoculars for Wildlife Viewing

Before purchasing a pair, you should know how to choose binoculars for wildlife viewing. You may be interested in magnification, the field of view, or close focus. Luckily, there are many different binoculars available in the market that can provide you with the quality of view you desire. Listed below are some of the most important factors to consider when purchasing a pair. These will help you make the best choice possible.

Exit Pupil size

When deciding how to choose binoculars for wildlife viewing, one of the most important factors to consider is the exit pupil size. The exit pupil is the circle that focuses the light that comes out of the eyepiece. Exit pupil size is best measured by dividing the objective lens diameter by the magnification. A 10×42 pair of binoculars will have an exit pupil diameter of 4.2 mm, while a 7×50 pair will have an exit pupil size of 7.1 mm. The bigger the exit pupil size, the better the image will be.

A small exit pupil diameter is acceptable in bright light, while a large exit pupil is preferred when viewing in low light. A 10×60 binocular’s exit pupil size is only 6 mm in bright light, while a 30×70 binocular’s exit pupil size is 2 mm in low light. Choosing a binocular with a larger exit pupil diameter will help you see more detail in low light conditions.

The size of the exit pupil in binoculars should match the human pupil. Otherwise, the light will not be able to reach the retina. A smaller exit pupil will provide better contrast and better clarity. Exit pupil size also affects how much light the binocular can see. Exit pupil size is important when choosing binoculars for wildlife viewing. You can use the size of the exit pupil to choose the right pair for your needs.

While the exit pupil size of binoculars is important, the size of the field of view is even more important. Higher magnification will make the background sky appear more dense than it actually is, which will cause black circles to appear around the images. A large exit pupil will reduce the contrast between the background sky and the image, so opt for a smaller exit pupil if you are wearing glasses.


Magnification is an important factor when choosing binoculars for wildlife viewing. Higher magnifications result in a narrower field of view, but a larger lens lets more light in. A good rule of thumb is a 5:1 zoom to lens ratio. Generally speaking, higher magnifications are better for spotting birds and animals, but they can be cumbersome and difficult to carry around.

When choosing binoculars for wildlife viewing, 7x or 10x are the most popular choices. Eight-to-ten-power binoculars have the best combination of image brightness, image stability, and lens design. In general, 7.5x and lower binoculars are the most suitable for bird watching and are useful for people who find it difficult to hold higher-magnification binoculars steady. For fast-moving wildlife, you will want a wide field of view. However, don’t forget that higher magnification has disadvantages.

A higher magnification means a smaller field of view. High-magnification binoculars can be viewed at a distance of 1,000 yards, but their field of view will be smaller than those with higher magnification. Magnification is also a factor, but it’s not the only factor. The size of the objective lens determines the quality of images that can be produced.

For bird watching, choose binoculars with a 35mm to 42mm objective lens. For a more detailed view, choose binoculars with a 50mm lens. Magnification is important for viewing wildlife, but it’s not the only factor. Lens coatings and the type of lens will greatly affect the quality of images. Make sure that the lenses are anti-reflective.

Field of View

While magnification is essential when it comes to wildlife viewing, there are other factors to consider before making a decision. One of the most important of these is the field of view. When choosing binoculars for wildlife viewing, it is important to understand how much of an area can be viewed through the optics. Field of view is the distance at which you can see an object at a glance. In fact, two binoculars with identical magnifications can have 90-foot difference in field of view. The higher the number, the brighter the image will be. It will also make the image easier to maintain when shaking.

Another factor to consider is the eye relief. The distance between your eye and the binocular lens is called eye relief. While most binoculars come with adjustable eyepieces, it is still essential to pay attention to the distance between your eyes and the lens. If you wear eyeglasses, you should look for a binocular with an eye relief of 11mm or more. Another factor to consider is the type of wildlife you are planning to observe.

One of the most important factors to consider when selecting binoculars for wildlife viewing is magnification. A pair of 8×42 binoculars will magnify an image eight times. However, if you’re a beginner, you may have trouble putting a bird in the binocular. A binocular with a wider field of view is more forgiving. A large magnification will mean that you’ll need to hold them steady, but a large field of view will allow you to enjoy the entire scene.

Close Focus

While many people use binoculars for viewing far-away objects, close focusing binoculars are ideal ones to choose for wildlife viewing. These binoculars can bring objects within four to five feet into focus. Some models can focus as close as three feet, making them excellent for wildlife viewing. Close focusing binoculars require that you close one eye to get the best picture. For this reason, it is best to keep the distance between your eyes as small as possible while using them.

When deciding on the right pair of Close Focus binoculars, consider the price and the features that you want. While most pairs are affordable, they are not as durable as other models. Many pairs of binoculars have little protection around the objective lens, and rubber coatings on the center portion of the body are not enough to protect them. Even though these models are lightweight, they do not sacrifice image quality. If you’re looking to view invertebrates or birds, 1.5-metre close focus binoculars are a great option.

In general, the field of view of a Close Focus binocular is the closest distance to which a sharp image can be achieved. In many cases, this distance will depend on the type of wildlife viewing that you’re doing. If you’re observing birds, for example, you’ll want to be able to observe details of the bird’s wings and tail without bending the binocular’s lens.

When choosing your Close Focus binoculars for wildlife viewing, consider whether or not you’ll need to adjust the eyecups. The eyecups usually have two settings: the center focus is fixed and the diopter is adjusted to correct for this. It’s also important to consider how comfortable the eyecups are. Try several different pairs and see which one suits you best. There’s no harm in trying one pair out in a store first.


One important feature to consider when you choose binoculars for wildlife viewing is the lens coating. Lens coatings are thin layers of fluid applied to the optics. These coatings can make a significant difference in image quality, making images appear brighter and sharper. They also help prevent internal fogging. Make sure to choose a pair that is waterproof. These will protect your binoculars from water and debris, as well as prevent the interior of your binoculars from fogging up when they are exposed to rain or snow.

The coatings on binoculars are primarily responsible for the brightness and clarity of the image. Some lenses have better clarity than others, so look for a binocular with good optical coatings. Borosilicate Crown Glass is the cheapest prism glass available. Magnesium fluoride is one of the most effective coatings for reducing reflections, reducing them to less than 5%. HD is an abbreviated form of high definition and is often used on porro-prism binoculars.

If you prefer a rugged binocular with good optical quality, you might want to consider Celestron’s outland X 10×42. It’s fog-proof, waterproof, multi-coated, and has Bak 4 enhanced optics. This binocular is rugged and designed for outdoor use. Its outer portion is designed to withstand shock, and has a firm grip for added comfort.

You’ll also want to check the field of view specs. These are the measurements of the area you can see at a glance if you’re standing 1,000 yards away. Two pairs with similar specs may have wildly different fields of view. Some have 90 feet wider fields of view than the other. Another thing to consider is the exit pupil. The exit pupil is the diameter of the objective lens divided by the magnification. It’s a key feature for wildlife viewing, especially at dusk and dawn when the light is poor.
