When you head out into the backcountry with a pair of binoculars, you always have to compromise. Since what makes a pair of binoculars particularly amazing is often a set of very large, very heavy, and very delicate high-quality lenses, as backpackers and hikers, we need to determine if we’re willing to carry and care for such a bulky and fragile object in the outdoors.
That’s where compact binoculars come into the picture. Significantly smaller, lighter, and more durable, compact binoculars are better prepared to handle the rough and tumble world of mountain pursuits while fitting easily into your backpack. While compact binoculars do have to sacrifice a bit on lens quality to achieve a smaller and more portable size, modern compact binoculars manufacturers have made incredible strides toward creating high-end optics for the outdoor enthusiast.
That being said, there are a whole lot of different compact binoculars out there, so it can be challenging to determine which pair is the best for your needs. To help you out, we’ve compiled this ultimate guide to compact binoculars, complete with a buyer’s guide and reviews of seven of the best compact binoculars on the market today. Here we go!

Compact Binoculars Buying Guide
Compact binoculars can be tricky to buy because there are so many different options out there in today’s market. This means that it can be really tricky to separate the higher-quality models from the low-end options. Thus, we’ll now take some time to discuss the different features that you’ll find on compact binoculars, so you can determine which pair is the best fit for your needs.
If you’ve ever spent some time perusing the binoculars section of an outdoor retail store, you’ve probably noticed that the binoculars come in a wide array of sizes. In fact, there are actually three main sizes for binoculars:
- Full size (e.g. 8×42)
- Mid-size (e.g. 7×35)
- Compact (e.g. 8×25)
As you might imagine, full-size binoculars aren’t really ideal for hikers and anyone else who’ll need to carry their binoculars for hours or days on end because their large lenses mean that they’re quite heavy and delicate. Additionally, while you might be tempted by the slightly higher quality lenses in a mid-size pair of binoculars, the added weight and bulk of this size range will quickly take away any of the optical benefits as you might come to regret your decision to carry such a heavy piece of gear into the backcountry.
Unless you’re a professional ornithologist or someone else who uses binoculars for their job, a pair of compact binoculars will probably strike the perfect balance between optical quality, portability, and functionality. Thus, when you’re shopping for compact binoculars, look for a pair that’s sized to around 8×25.
Field of view
A binocular’s field of view refers to the width of the area that the lenses can cover. This is similar, in many ways, to a human’s field of view, as we can only see so far to either side of our heads before we need to turn our heads to be able to see an object.
In the world of binoculars, field of view is either expressed as an angle (e.g. 8°) or as the width of the image in feet, yards, or meters (e.g. 1000 yards). A field of view of 1000 yards is considered the gold standard for most compact binoculars, though you’ll occasionally find models with smaller or larger ratings in this metric.
Generally speaking, a wider field of view is best when you’re looking for a small object on the move in a large space, such as a bird flying through the landscape. A narrow field of view, on the other hand, is best for looking at a stationary object in high detail.
That being said, a binocular’s field of view rating will always require some degree of a tradeoff. This is because while a narrow field of view allows one to see objects in high detail, it makes it harder to find a small object in a vast landscape. Binoculars with wider fields of view provide panoramic views but are less focused on the details. Thus, the field of view you want in your binoculars really comes down to what you’ll be using the binoculars for.
Magnification power rating
The main reason we use binoculars is to magnify our field of vision so we can see objects that are way too far away for our normal eyesight to see. Thus, when we buy compact binoculars, it’s essential that they have a high-enough overall magnification power to let us clearly see objects in the distance.
All binoculars come with a magnification power rating, which is actually a set of two numbers. In fact, these are the very same numbers that tell us what size the binoculars are (e.g. 8×25). This rating might seem confusing, but when you break it down, it actually makes quite a bit of sense.
The first number in the rating, in this case, 8 for most compact binoculars, refers to the overall magnification power of the lenses. This means that binoculars with a rating of 8×25 have a magnification power of 8-times.
The second number refers to the diameter of the objective, or outer, lens in millimeters. Thus, binoculars with a rating of 8×25 have a 25 mm lens that magnifies objects eight times.
The diameter of a binocular’s lens is actually quite important when we talk about magnification. This is because a larger lens can capture more light and allow you to see brighter and clearer objects in low light conditions. However, larger lenses increase the weight, bulk, and fragility of your binoculars, so it’s best to stick with a compact pair for most outdoor pursuits.
Many binoculars now sport some sort of coating on their lenses. These coatings can sound very complicated, but really they are just a thin chemical coating that reduces the amount of light that gets reflected off of the surface of the lens. By reducing the amount of reflected light, the lens coating improves light transmission through the binocular for a better quality image for your eye.
Lens coatings are actually quite important as each lens in a binocular can reflect off up to 5 percent of the light that attempts to pass through it. Since binoculars have multiple layers of lenses, this could mean a loss of up to 35% of light for a lower-quality pair. High-quality lenses with multiple coatings can reduce this light loss down to only tenths of a percent.
That being said, there are many different kinds of lens coatings. Here are a few:
Lenses described as “coated” have a thin layer of anti-reflective coating on one or more of the lens surfaces. This coating is often made of magnesium fluorite.
Fully coated lenses have a thin layer of anti-reflective coating on both sides of the outer (objective) lens. They also have a thin layer of coating on both sides of the ocular lens and the long side of the prism.
Lenses labeled as “multi-coated” have multiple layers of anti-reflective coating on one or multiple lens surfaces. That being said, many really high-quality binoculars only have a single layer of anti-reflective coating on the outside lens.
These lenses have multiple coatings on all of their lens surfaces. This is often found in high-quality binoculars; however, just because something is fully multi-coated doesn’t mean it produces the best quality image. That being said, fully multi-coated lenses do indicate that the manufacturer has put a significant amount of care and detail into creating these binoculars.
Although there aren’t any electronics inside most binoculars, if you spend a lot of time backpacking, you’ll still want to have a pair of binoculars that are at least somewhat water resistant. This is because when rain, moisture, and water vapor get inside a pair of binoculars, they can condense and cause fog to form on the inside of your lenses.
This fog can even form whenever you go from a cool environment, such as a car or house that’s air-conditioned into a warm, moist locale, such as the outdoors in the summer. While this fog will hopefully clear up before too long, this process will often take hours, so your day of birding or animal spotting in the backcountry will be ruined before it even gets started.
Thus, it’s in your best interest to ensure that your compact binoculars are waterproof. Such binoculars are ready to handle rapidly changing weather conditions (like what you’d find in the mountains) because the insides are protected from both dust and water vapor.
Most waterproof binoculars are actually sealed and filled with a dry (e.g. water vapor-free) and inert gas, such as nitrogen, so it’s impossible for condensation to form inside the lenses. Therefore, when shopping for waterproof compact binoculars, you’ll want to keep your eye out for the words “nitrogen purged” or “nitrogen filled” as this generally refers to a waterproof model.
Another method that companies use to discuss waterproofing is the IPX standard for waterproofing. This system is somewhat complicated to describe, but basically, all binoculars using this system will be given a rating between IPX0 and IPX8 with the lower number denoting a product that’s not at all waterproof and the higher number designating a product that can be submerged in 3 feet of water. For our purposes, anything rated above IPX4 will do for waterproofing on binoculars.
A prism is a piece of glass that is cut into a particular shape with precisely defined angles and faces. They are useful for reflecting light and analyzing it. In fact, you probably played with prisms as a kid in school and found that they can separate white light into all of the colors of the visible light spectrum.
In binoculars, prisms correct the image orientation that is produced by the objective (outside lens). This is necessary because the objective lenses of binoculars actually form images that are upside down. Since we humans don’t really like looking at an upside down image, we can use prisms to turn an image upright inside binoculars.
Prisms also reduce the overall length of binoculars by changing the light path. By bending the path of light within the binoculars as the light travels from the outside lens to our eye, the prisms allow binoculars to be much smaller than they could otherwise be. This is especially great for those of us who love compact binoculars.
There are two main types of prisms in modern binoculars: Porro and Roof. Porro prisms used to be the standard design in binoculars and are easy to identify due to their wide, bulky shape. These days, Porro prisms are more commonly found on cheaper binoculars where size and weight are less of an issue.
This is not to say, however, that they don’t work well, but rather that their size and bulk can be a hindrance to the light and fast backpacker. Although the Porro prism has faded from popularity, they are still a good option for people on a budget.
The other prism option for binoculars is the roof prism. The roof prism was created by Zeiss and is designed to be more streamlined and compact. This means that roof prisms are ideal for compact binoculars as they can be less bulky than their Porro prism counterparts. However, roof prism binoculars tend to be a bit more expensive than other alternatives, though this is changing as they become more popular.
Much of the value of a pair of binoculars comes from the quality of the lenses and the lens glass itself. That being said, there are many different kinds of lens glass out there, so we can’t possibly list them all here. However, here are some of the more commonly known types of lens glasses on the market today:
- BK7 Glass: This kind of glass is generally considered to be low quality and is found mainly on cheap binoculars. The main problem with this kind of glass is that it often has an issue known as chromatic aberration, wherein an image looks fuzzy, even when in focus.
- BAK-4 Glass: One of the most commonly used glasses for binoculars, it is of medium to high-quality thanks to its low refractive index and resistance to chemical and environmental damage.
- ED Glass: ED stands for “extra-low dispersion,” which is a process that helps reduce the issue of chromatic aberration. This kind of glass is popular in high-end binoculars because it can provide crisp images at higher magnification.
Buying compact binoculars is a test of compromise. Although we want our compact binoculars to be small, lightweight, waterproof, affordable, and provide fantastic images, it can be difficult to find a pair that can meet all of our needs.
Thus, we recommend making a list of the top features that you want to have in your binoculars and rank them in order of importance. This will help you decide between similar pairs of binoculars so you can find the set that’s right for you. Happy trails!
