The coating on a lens has almost as much to do with clarity and brightness as the lenses themselves. A good coating can reduce the amount of scattered light down to a quarter of a percent per a surface. Scattered light is lost or misaligned information. You can have the best lens and coatings, but if all the elements aren't lined up and centered your image will come out distorted. With a minimum of 6 elements and some models having up to 20 elements, plus the two barrels, getting everything aligned can be very difficult. Fortunately, our brains are good at compensating for small misalignments. However, misalignments can add to eye strain.
Bill Stewart says that he has seen many beginning birders make the mistake of buying binoculars based on a brand or recommendation and then finding themselves disappointed with the feel or view they experience in the field. He also has seen birders “buy down instead of up” to save some money initially. They often end up spending more the second time around when they feel that they need to upgrade to a better pair, he says.
Every pair of binoculars has two numbers printed somewhere on the instrument (usually on the face of the focus wheel, but sometimes on the body of the binocular) — for example 10×42 (pronounced ten by forty two) or 8×32. The first of these numbers is the binocular’s magnification, the second is the diameter of the objective lens (we’ll get to that in a moment).
These binoculars are sealed with O-rings to prevent moisture from getting inside; but they can still fog up on you. Depending on the construction and the seals, some waterproof binoculars are also submersible for various amounts of time. Certain manufacturers rate their binoculars for limited depths for limited amounts of time; others will adhere to military standard specifications and rate them for much greater depths.
There are a number of binoculars with large eye relief, that are ideal for those who wear glasses. If you have used a bin without decent eye relief in the past, you know what a pain it can be. My recommendation for glasses wearers, are either the Swarovski EL (premium price, 20mm relief) or the Vanguard Endeavour ED II 8×42 (affordable price, 19.5mm relief), depending on your budget.
Again, you tend to get what you pay for here to some degree, and optics from established top-flight brands are usually incredibly well made (my binoculars are still the best made piece of equipment I have ever owned). That said there are plenty of very well made binoculars in the low-to-mid range from manufacturers who take quality every bit as seriously as the premium brands.
These binoculars provide the widest field of view of all the binoculars tested by Top Ten Reviews. This means that the Action EX Extremes "are ideal for situations in which you want to track fast-paced movement," like bird-watching or sporting events, Top Ten Reviews states. With a relatively low magnification of 7x, these binoculars won't allow you to see quite as far as Celestron's SkyMaster binoculars do. However, the lower power helps to eliminate the shaky images caused by small hand movements. But what these binoculars lack in magnification, they make up for with optical quality. "Nikon Action EX Extreme produced some of the best images out of all the binoculars we reviewed," Top Ten Reviews states. However, these are best used for daytime observations. The binoculars have 35-mm objective lenses, which is a relatively small setting and means that these binoculars won't catch as much light in low-light settings. The Action EX Extremes are also fog-proof, waterproof and durable enough that you can use them outdoors without worrying about damaging them.
We review the best birding binoculars available on the market and offer you our selection below. Do you have questions on how to choose bird watching binoculars for your specific application? While the typical optics consumer often favors high powered binoculars (16x is quite popular these days!), the more discerning birdwatcher has traditionally preferred relatively low power binocular models (7x, 8x and some 10x). High power certainly has its place in Bird Watching Binoculars, if you need to view small details at a greater than average distance, but lower power optics in your birdwatching binoculars have many advantages. One of these is exit pupil, which translates to binocular brightness. For example, when comparing two similar birding binoculars with the same objective diameter, such as an 8x42 and a 10x42, the lower power unit will have a larger exit pupil (42/8=5.25 vs 42/10=4.2), and therefore deliver more light to your eye. This is an advantage when you are out at dawn or twilight, or looking through binoculars at markings on a bird that is in the shadows of a tree. Lower power birdwatching binoculars typically provide a wider field of view, handy for scanning a large area for subjects of interest or more easily following moving objects, such as a bird in flight. Finally, you may have noticed that an 8 power binocular seems easier to hold steady than a 12 power binocular (we do have spotting scopes and binocular tripods and binocular tripod adapters that will work great with these binoculars!). The higher power, along with the narrower field of vision, makes small movements of your hands and body more noticeable, but larger objective and top quality lens coatings help to keep the view bright enough to be quite usable. Take a look below at our nature/birdwatching binoculars on sale and see what better fits your birdwatching needs. We guarantee you will not be disappointed!

Binoculars are much easier to learn to use than a telescope. It's a little like comparing a point-and-shoot camera to the type used by professional photographers. You intuitively "point" the binoculars at what you wish to see and look through them. This intuitive "pointing" makes it significantly easier to find objects and subsequently move from one celestial object to the next. It's easier, using binoculars, to learn the locations of planets, constellations, galaxys, and clusters and observe their orderly movements — thus establishing the foundation for greater understanding.
Binoculars that share the same magnification and objective lens diameter can deliver vastly different levels of optical performance. The quality of the optical components, the design of the optical system itself and the care and attention to detail during construction all play a role in a binocular’s overall optical quality, as do the quality and application of special coatings to the lenses and prisms (see below).

Review additional features and warranties. Pay attention to field of view and close focus, two measures that affect how much you’ll see. See our report on field of view and close focus to understand how these factor into your choice. Also pay attention to durability, waterproofing, and warranty—many major optics companies now offer excellent warranties. Check our full review spreadsheet for these details.

With the built-in ID (Incline/Decline) Technology, you’ll have angled compensated distances to accurately adjust your riflescope for holdovers. You’ll be able to clearly see your readings with the LED display that has a 4-step brightness intensity to adjust for any time of the day. Pleasantly, Nikon doesn’t disappoint, and we say “Welcome to the playing field, Nikon.” We’re super stoked to see the LaserForce make its presence known as they’ve only hit the 2017 market. We’re proud to put both thumbs up to their optic – job well done!
Designed to be as light as possible with maximum ergonomic comfort, these Nikon Aculon binoculars aren’t giant, but they’ve been found highly useful for nighttime stargazing. If you’re just looking for a high-class set of ‘regular’ size binoculars, you’ll have a hard time going wrong with these. Recommended by amateur astronomy class teachers, the Aculon 7×50’s cost about a fourth of professional grade astronomy binoculars, but provide much of the same performance.
Pro Tip: Hunters, birders, and astronomers should keep the magnifications at 8x and below and boost the objectives up over 50mm to produce really wide exit pupils, such as this pair of 8x56 from Steiner. I used this specific pair in the middle of the night and they could completely cover my pupils, which boosted my ability to see, despite the dark surroundings. Boaters should also consider this type of configuration because the wide exit pupil will help to minimize the disorientation that is common when viewing through binoculars on pitching or rolling water.
Whether you're looking for an inexpensive first pair of binoculars, or want a good, secondary, compact pair that won't break the bank, the Vortex DiamondBack 8x28 will serve you well. These relatively small bins tip the scales at just 15 ounces, yet can provide enough brightness and clarity to identify small birds on a bright day. Top that off with high-quality construction and a smooth focus knob, and you've got an excellent pair of budget bins.

Now, if you take a look at precise tests, you will find that the binoculars actually provide a very accurate reading, save for the target at 1200 yards. This actually depends on the target. Most of today’s rangefinder binoculars produce a beam that’s shaped as a horizontal rectangle. However, the Fusion actually has a vertical beam. According to Bushnell’s engineers, this helps optimize the performance for some of the most common hunting scenarios of today. A vertical beam can easily hit the intended target, instead of a nearby bush by mistake.


Rangefinders are an important part of your hunting or sporting routine. It is a device which allows you to measure the distance between you and the target. On the other hand, binoculars are the device which is used to observe objects which are further away from us. When these devices were combined to make a binocular which can also show the range between you and the object, it resulted in the manufacture of rangefinder binoculars. Rangefinder binoculars are extremely handy because of the ease of use and the features it has.
Sticker shock is common when looking for your first pair of bins. If you're timid about spending multiple hundreds of dollars on a new hobby, the Celestron Nature DX 8x42 is a perfect choice. The image quality of these binoculars, which list for just $140 and often sell for less, is by far the best we've seen in this price range. In fact, it rivals models that cost more than twice as much in that regard. The supple focus knobs and easy eyecup adjustments continue the beginner-friendly trend. We also enjoyed that the 6.5ft focus range let us get a good look at any nearby butterflies or other interesting insects, a big plus for days when the birds just aren't singing.
Let's have a brief word about why stabilization is of interest before discussing the differences in mechanics and their results. The stabilized image will allow you to actually see not only subtle differences in color hues, but also where they start and end. If your binocular's optics (without image stabilization) would otherwise allow you to see them, the tiny movements of your hands caused by things so innocuous as your heart's rhythmic beating or breathing will usually blur these fine details. Consequently, the detailed image afforded by stabilized binoculars is much better than that typically seen in non-stabilized instruments.

Resolution: resolution is a measure of your binocular’s ability to reveal the fine detail in the subject you’re viewing (individual feathers in a bird, for example), and of course a higher resolution image with more detail is always better. The main factors that affect the resolution of a binocular are the size of the objective lens, the magnification, the quality of the optical components and the lens and prism coatings.
Cometron 7×50 binoculars from Celestron is an ideal pair of binoculars for amateur or beginner users. With 50mm aperture, it gathers enough light to provide a bright and sharp image of stars, comets, and craters of the moon. Cometron also provides 6.8-degree wide field of view that helps to locate objects in the sky without constantly moving the binoculars.
Binoculars are not required for birding, of course. Audubon’s Eric Lind recommends going out with a group of birders and trying their binoculars before you make a purchasing decision. The social aspects of birding, the sharing a sense of wonder and discovery, and the life-long learning experience is what makes birding so popular. There is no better way to cultivate that aspect of birding than through sharing the view of a bird through a friend’s binoculars or by handing your favorite pair to a family member to let them share in the experience.
Though a bit on the portly side at 23.6 ounces, there’s a simplicity of design and ease of use that’s hugely gratifying in the field. This may sound like small potatoes, but the tethered lens covers and rain guard are far and away the best I’ve ever come across. Most require substantial wrestling, while these slide right on and off. For what it’s worth, I also didn’t have a minor cardiac event while adjusting the neck strap. With a field of view upwards of 340 feet at 1,000 yards, and amped-up magnification for long-range birding, the Ranger EDs feel like a rare triumph of design over wallet slenderness.
The latest product from this direct-to-consumer optics brand is a big 15X configured for open-country hunters. The B.4’s lightweight polymer chassis makes it lighter than it looks, and a mid-frame ridge offers great purchase for those who hand-hold the binocular. While our test model was in plain black and gray, buyers can dress this optic up in their choice of camo patterns and colors for an additional fee. The optics were a little disappointing, and testers gave demerits for the boxy, overlarge eyecups. But the price is fair for a big, albeit niche, bino.
The Razor HD is argon-filled and sealed with O-rings to ensure reliable and durable protection against dust, debris, fog and water. It is rubber armored for non-slip and durable protection, and is equipped with a large focusing knob that is easy to use even while wearing gloves. Naturally contoured to perfectly fit your hands, promoting comfort and eliminating user-fatigue Vortex has once again created a winning combination of features.

Vixen Optics' Atrek II 8x32 DCF Binocular gives you a compact optic that fits comfortably your hand while having the benefits of a nearly full-sized binocular. A combination of features work together to produce bright and clear images with increased contrast and true color rendition. These features include BAK4 roof prisms for improved color and contrast, anti-reflection fully multi-coated optics which limit light loss for brighter images, and field flattener lenses which virtually eliminate distortion at the edges for clear images across the entire generous field of view. The Atrek is offered here in a 8x power which provides a nice general purpose magnification with a wide 60° apparent angle of view.

We are also big fans of the unique "Uni-body" design. The dual lenses are locked in a single housing with the eyepiece built for synchronizing movement. Just because they're small though doesn't mean you have to sacrifice quality or durability. These binoculars can still take in breathtaking images with their 21mm lens and 8.5x magnification that boasts exceptional edge-to-edge sharpness.
For a premium experience while hunting or birdwatching, the Vortex Optics Viper HD Roof Prism Binoculars are the pair for you. Their massive 50mm objective lenses offer high-end performance with a full-size feel and edge-to-edge clarity. The binoculars also magnify at an impressive 12x, with a field of view of 288 feet at 1,000 yards. They're also built with lifetime fog and waterproofing performance with ultra-hard scratch resistant armortek protection.
One of the best ways to test a wide selection of binoculars is by visiting the Optics Department at the B&H Photo SuperStore in New York City. The store has a huge number of binoculars on display for you to look through and hold while you talk to optics experts at the counter. The B&H Used Department also has a constantly changing selection of great binoculars available at discounted prices.
The down side to long eye relief is that it usually reduces the field of view. Some people wonder if you need to wear glasses at all using binoculars, well If you are near-sighted or far-sighted, you can use your binoculars without wearing glasses and the binoculars focus will compensate, but if you have astigmatism, you will need to use your glasses.
I too am shopping for a pair of binoculars for my husband for Christmas. We live in a condominium building overlooking Lake Superior and he likes to look at the cargo ships coming in and out and the different boats on the water. I am thinking something 10x or 10-30x. We would probably just keep it mounted on a tripod if I bought a heavier set, but would prefer something lighter. 
The 7x50 configuration, tough body designed to withstand the elements as well as it's bright image, wide field of view and of course the rangefinding reticle, digital GPS and compass mark these Celestron binoculars out as the ideal companion for boaters, security and military personnel as well as hunters and especially those involved in search and rescue operations.

Look for lenses of good quality, multi-coated if you can afford it since the targets you pursue are so far away that you can make use of any additional feature you can get. Better quality lenses will increase sharpness and brightness, enhance contrast and generally render a better image than low-quality ones. It all comes down to your budget and preferences, of course.


The accuracy is mostly due to the advanced ranging modes available on the Fusion 1 Mile. They allow the user to provide hints on how to interpret readings based on his or her surrounding circumstances. This decreases the chances of inaccurate readings based on tricky scenarios. The abilities of the Bushnell 1 Mile are impressive for any model, but they are even more exceptional considering the cost of these binoculars. This model can by purchased for less than $1,000.
Since you're not looking at really far distance, I don't think you need anything more than 6x or 7x...this lower power will bring the subject in close while maintaining a wide field of view. If you need  more power, I wouldn't go any higher than 8x. Also, depending on the objective lens diameter you go with, keeping the power to the 6-7x range you'll also benefit from a wide exit pupil and (generally) longer eye relief.
The terms “angle of view” and “field of view” are complementary. Both terms describe the amount of scenery, measured horizontally, that is visible when looking through a binocular. Imagine standing in the middle of a giant pizza pie; binoculars with a 6.3-degree angle of view would show the viewer a 6.3-degree “slice” of the 360-degree pie, looking outward.

"My 4-year old son loves his new binoculars and compass. He loves to pretend to go on adventures and look through his binoculars at things far away. Santa Claus brought him these binoculars, and he still has interest in them a week later, which for my four-year-old is pretty amazing. He's more of the 'let's-play-with-a-toy-for-five-minutes-and-then-quit' kind of kid. As binoculars go, these aren't like most 'toy' binoculars, where you can barely make out what you are looking at due to the blur. They are actually very clear and cover a good distance. I'm really impressed with them!"
To find a manageable group of testing finalists, we first eliminated companies that make only one model and that don’t exist outside of their Amazon presence. We also ruled out companies with just one model in our target price range, based on the logic that those binoculars are less likely to be widely available in the future, particularly if they get damaged and you need to return them. This left us with 17 models of 8×42 binoculars, priced mostly under $350:

It can also handle some of the toughest ranging scenarios with a small beam divergence. The model has exceptional optical quality that results in clarity beyond 1,400 yards. This is due to the fluoride glass used for its optics. The Victory RF is designed with comfort in mind as it features large easy-to-press buttons that click when pressed. The Zeiss Victory RF costs $3,300 for this 10×56 model and less than $3,000 for the 10×45.
The design of the rangefinder binocular makes a big difference. It has to be compact and lightweight for you to easily handle. The weight defines how easily you can take it with you. You should have the ability to carry it with you without being fatigued. Also, if it is too compact, there is always a chance of the device falling off from your hands. A balance between compactness and weight would be the ideal match for a good rangefinder binocular.
We expected this boxy, two-tone binocular from Cabela’s to cost so much more than its asking price of $190. Mechanically and stylistically, it seems like an optic that might compete with $1,000 offerings from European brands. We liked the Intensity’s crisp two-position eyecups and oversize focus wheel, front-hinge tripod adapter, fine balance and hand-gripping texture, and high-quality nylon carry case. By delivering all those features for under $200, the Cabela’s bino wins our Great Buy award.

The SkyMaster Giant 15x70 binoculars by Celestron have one of the highest magnifications of all the binoculars that Top Ten Reviews checked out, making these ideal for looking at stars, planets, comets and other distant objects in the night sky. Images appear crisp and clear though these binoculars, but you may need a tripod to keep the view steady with such a high magnification (15x). The binoculars have large, 70-millimeter objective lenses that direct ample light to your eyes when used in a low-light setting. And if you wear glasses, you can rest assured that you don't need to take them off before looking through these binoculars.
