Reviews, Comparison and Buying Guide
What is a Binocular
At their most basic level, binoculars are two telescopes attached side-by-side that allow the viewer to see distant objects.
How a Binocular works?
Every pair of binoculars is made up of two lenses: the objective lens (which is closest to the object), and the eyepiece lens (which is near the human eye). The objective lens combines convex and concave lens to capture an image, and the image is then magnified by the eyepiece lens – so that you can clearly see a subject or landscape that’s far away.
Best Binocular Buying Guide : Things to consider while buying a Binocular
There are a surprising number of factors to consider when buying a pair of binoculars. The good news is, once you know the basics it’s actually very easy to choose one that fits your needs. In this binoculars buying guide, we define and explain everything on the list.
Types of Binocular
- Foldable binoculars – If you don’t need standard, full-size binoculars, foldable models are compact and lightweight. They can easily fit into a handbag or backpack, and are ideal for concerts, theatre and the opera.
- Wide angle binoculars – We’ll delve into this soon, but these binoculars have a wider Field of View (FOV), so they’re great for spotting objects across larger areas.
- Zoom binoculars – As the name suggests, zoom binoculars have more choices when it comes to magnification. (If you’re a photographer, think of these in a similar way as zoom lenses, while ‘fixed power’ binoculars are closer to prime lenses).
- Waterproof binoculars – Some models are water-resistant, which means they’re protected from water splashes. Waterproof binoculars are fully weather-sealed and can be completely submerged in the water. On that note, shockproof binoculars are perfect to take on bumpy adventures, like safaris or rides on a speedboat.
- Focus-free – These are often called self-focusing or auto-focusing binoculars, but those terms are misleading. Focus-free binoculars don’t have a focusing mechanism. Instead, they have a fixed depth of field, and everything within that range will remain in focus.
- High-powered binoculars – Ideal for long-distance terrestrial viewing, high-powered binoculars have a super-high magnification. Many astronomers use them as an alternative to telescopes.
- Tripod-mounted binoculars – Like cameras with a large zoom range, binoculars with high magnification power will deliver a clearer, steadier image when mounted on a tripod. If you often shake when you’re holding binoculars, look for a pair that’s compatible with a tripod.
- Night vision binoculars – Put simply, night vision binoculars turn photons into pools of light that are visible to the human eye. Even simpler? They allow you to see your subject in the dark. These binoculars are used for sports and surveillance purposes, as well as other leisure activities.
Magnification and Objective
All binoculars are identified by a set of numbers, such as 10×42 and 7×20, which refer to their magnification and objective lens diameter, respectively. Using 10×42 as an example, the 10x means that the binoculars have 10x magnification power, making the view through them appear 10 times closer than it appears to the naked eye.
Field of view (FOV) and range finding
The field of view is the width of the scenery you can see through your binoculars. It’s measured in degrees, and the larger the number, the wider the FOV. Binoculars with wide FOVs are good for scanning scenery, and observing quick movements (like a fast-paced sports game, or animals chasing each on safari). Many binoculars are also equipped with a rangefinder. This superimposes a scale on your image, so that you can estimate your distance to the object. The feature comes in handy if you’re hunting or golfing.
Eye relief is the optimal distance from the eyepiece to your eye, or the focal point where the light passes through the ocular lens (eyepiece). Manufacturers install eyecups on the eyepieces to place the user’s eyes at the proper distance from the eyepieces to make using them easy. If you wear glasses, the lenses will position the eyepieces past the eye relief distance, affecting the image quality and your ability to achieve sharp focus. Many binoculars offer dioptric adjustments on one of the eyepieces so that most users can fine-tune the focusing system to their eye prescriptions to use the binocular without their glasses. If your prescription is difficult, or you’re sharing the binocular with other users, the eyecups are often adjustable. Basic eyecups simply fold back to allow you to place your eyeglass lenses closer to the ocular lens. Another type is adjustable eyecups that twist in and out to set the proper distance for the individual user precisely.
The type and quality of the glass used for the lenses and prisms matter. Generic optical glass may have imperfections, and if it isn’t ground and polished correctly, it could bend light oddly, causing colors to look skewed or prevent its ability to achieve tack-sharp focusing, or you may notice distortion at the edges. Specialized glass, such as low dispersion or extra low dispersion, is engineered to have virtually no distortion and transmit light better without bending it. The resulting images are generally clearer, sharper, with true color rendition and higher contrast.
Lens coatings are films applied to lens surfaces to reduce glare and reflections, increase light transmission and contrast, and help make colors look more vivid. Any light reflected is light that never reaches the viewer’s eyes, so by eliminating reflections, the image ends up being brighter and sharper. Coatings, in general, are good, provided that the coatings do something. It’s easy to put a cheap coating on a lens to give it a cool-looking orange tint, but the coating might not do anything to improve image quality.
Complementing lens coatings are prism coatings, which increase light reflection and improve image brightness and contrast. While many manufacturers may use standard reflective coatings, the upper echelon of prism coatings is called dielectric coatings, which allow almost 100% of the light through the prism, resulting in brighter high-contrast images.
The clear majority of binoculars use a center focus system. The main focus wheel is set on the bridge between the two oculars and moves them symmetrically. With center focusing, many manufacturers will have a dioptric adjustment dial on one of the eyepieces to fine-tune the focus to match individual optical prescriptions. The dioptric correction amount is decided by each manufacturer, usually by model, and can be on the left or right eye, or both. Certain models have the dioptric correction integrated into the center focusing mechanism.
This feature auto-corrects any jitters or shakes that can easily happen when you’re using a high magnification – especially if you’re holding your binoculars or sitting in a moving vehicle.

Adjust the width of your binoculars so that each eyepiece is aligned with your eyes and that when you look through them, you see a single, perfectly round image free of shading. Focusing the binoculars, for center focusing binoculars, look through the left eyepiece with your right eye closed and turn the center focusing wheel to focus on an object. Then look through the right eyepiece with your left eye closed and turn the right diopter ring to focus sharply on the same object. Make note of the + or – diopter setting as this will remain constant unless your eyesight changes. Both sides (eyes) are now in focus and you will need to use only the center focus wheel to focus on the other objects.
