How to choose the best binoculars in India?

You have been thinking about buying binoculars for a long time, but you have no idea how they work or which ones would be ideal for your needs. This handy guide on how to choose the best binoculars in India will help you in your search until you find the right one! The first thing to do is undoubtedly become familiar with the technical language and these basic features will make you understand the different potentials.

1. Use of binoculars

The optics you choose will depend on the use you intend to make of the binoculars. Some models are suitable for observing birds and natural elements, while others also integrate a night vision system, while still others are excellent theater binoculars. For this, it is essential to check the number of enlargements and the diameter of the objective lenses, because on the basis of these factors, the brightness of the enlarged image and the width of the field of view depend.

Recognizing these data is very simple. Generally, after the name of the product some numbers are inserted (for example 8 × 42) which represent the number of enlargements and the diameter of the lenses in millimeters. We can divide the types of binoculars according to the following uses:

  • Hunting: For hunting we recommend fully rubber coated, waterproof and fog-free models with a magnification of 7x to 10x for general hunting or 12x to 16x for long range sports. Compactness is essential for hunters on the go.
  • Bird watching: 8 × 42 binoculars are the standard for bird watching enthusiasts, but 10 × 42, 10 × 50 and 12 × 50 models are required for detailed observation of smaller and more distant species. Compact binoculars with 30mm diameter are recommended.
  • On a boat: Any waterproof model with a large lens diameter and rubber coating. Preferable types are 7 × 50, 7 × 42, 8 × 42, and 10 × 42.
  • Concerts / theaters: Wide angle 5 × 25 and 8 × 25 binoculars are preferred, or compact 4 × 30, 7 × 18 and 7 × 21 models.
  • Outdoors: Any 7×35, 7×50, 8×42 and 10×42 will be perfect. Among the compact ones we suggest the 8 × 30 and 10 × 30. We also recommend waterproof models for camping.
  • General use / vacation / excursions: For general use with limited needs, we suggest 7 × 35, 8 × 42, 10 × 42 and 10 × 50 binoculars, compact and wide angle.

2. Type of prisms

The prisms are particular reflecting and refracting elements that have the purpose of straightening the image through a series of refractions. Basically, the prisms that can be found on binoculars are two types, each of which with its own advantages and disadvantages:

  • Porro prisms
  • Roof prisms

Porro prisms are those made with the greatest constructive simplicity and, precisely for this reason, they represent the least expensive choice. With this type there are fewer refractions, and less light is dispersed. As a result, you will have a brighter image. Unfortunately, however, this type of prism is decidedly heavier and bulkier, and carries with it a significant bulk even in width.

Roof prisms, on the other hand, take their name from their characteristic shape and are technically more complex than those of Porro, because they use a greater number of surfaces that must be positioned with absolute precision. For this they are more expensive, but also smaller and lighter.

Generally, in small binoculars and with low magnification (up to a maximum number of 8x) roof prisms are used, while in larger binoculars Porro prisms are used.

3. Lens material

The material with which the lenses are made is one of the factors that determines their quality. Generally, the lenses of binoculars are made of glass, but two types of glass are used on the market:

  • BAK7: The lenses in this category are made of borosilicate glass, a type particularly appreciated for its resistance and high degree of transparency.
  • BAK4: The lenses in this category are made using a Crown-barium glass, which is distinguished by a low refractive index and low light scattering. Basically, it is the best type of glass for the production of scopes, which makes it more expensive than the BAK7.

4. Anti-reflective treatment

Generally defined with the term “coating”, the anti-reflective treatment that the lenses have received is another factor to be taken into consideration. On the market you can find four different types of anti-reflective treatment, which are distinguished by characteristics and price:

  • Coated (C): A single layer of anti-reflective coating has been applied to the outer surfaces of the objective and eyepiece lenses.
  • Multi Coated (MC): Multiple anti-reflective layers have been applied to the outer surfaces of the lenses. This statement does not specify the number of layers applied.
  • Fully Coated (FC): A single anti-reflective layer has been applied to the external and internal surfaces of the lenses, as well as to the external surfaces of the prisms.
  • Multi Fully Coated (MFC): All surfaces of the lenses and the outer surfaces of the prisms have been treated with multiple anti-reflective layers. However, the number of layers applied is not specified.

A single application of the anti-reflective layer can reduce light scattering and bring it to 5%. The application of multiple layers can lower the dispersion even bringing it to 0.25%.

5. Phase correction

Phase correction is a factor to be considered only in models using roof prisms. It is a corrective layer applied to the optics that reduces the problems of distortions due to the constructive complexity of the prisms. This particular process substantially restores the image quality and relative sharpness, which could undergo variations due to the large number of prisms used.

6. Brightness and exit pupil

The brightness of the binoculars is expressed under the words “brightness index”, or “pupil exit”. It is a very important factor that depends on the combination of magnification and lens diameter and basically represents the amount of light that enters the device and that that comes out of the eyepieces.

The diameter of the exit pupil, i.e., the image seen from the eyepiece by positioning the telescope at a distance of about 30 cm, depends on the ratio between the diameter of the lenses and the number of magnifications. It is therefore important to always check that the exit pupil is consistent with the specifications of the chosen model and the relative magnifications and diameters: for example, if a 10 × 50 binocular has an exit pupil of less than 5 mm in diameter, it means that the diameter of the lens is not actual 5 cm as stated.

Binoculars with a large exit pupil will allow the observation at dusk of things that you would not be able to see with the naked eye and is particularly suitable for astronomical observation. If instead you want to use the apparatus for observing animals, birds, and excursions, you might consider buying a model with a brightness effect between 3 and 4.

To transmit enough light to the eye to allow vision, binoculars for night use must exceed 6 mm in diameter of the exit pupil but not surpass 7 mm. Twilight binoculars should be at least 5 mm in diameter, and daytime binoculars should be at least 3 mm in diameter.

7. Field of view

The field of view is another factor to consider before buying which basically depends on the number of possible enlargements. When it is expressed, the maximum distance observable from your position is indicated, for example 1000m, 100m, 400m, etc. And it is on the basis of this factor that another very important thing must be considered: the greater the magnification power of the binoculars, the more restricted will be the portion of land that it allows you to observe.

If you want to observe animals with a discreet level of detail, you will need a good number of enlargements, resulting in a loss of field of view. If, on the other hand, you want to be able to follow a moving animal within a rather wide panorama, you may prefer binoculars with less than 10 magnification and consequently with a wider field of view.

8. Eye relief

This adjustment performs a double function. On the one hand it allows you to place the binoculars on your face, shielding the eye from sunlight, on the other hand it allows you to precisely match the outgoing pupil with the pupil of the observer. This second function is the most important for a correct vision of the image transmitted by the binoculars, especially in changing lighting conditions.

As the size of your pupil changes, the pupil extraction will also have to vary. The adjustment is obtained through two soft cups placed on the eyepieces, removable and adjustable to the desired length. There are two types of possible eye relief adjustments:

  • Removable cup: The most customizable, since the cups can be more or less extracted with a screwing movement, lengthening or shortening the eye relief.
  • Collapsible cup: Less versatile, the cups can be folded in only two positions, closed on the tubes, therefore with zero eye relief, or “open”, with fixed distance eye relief.

Unfortunately, many low-end models are completely devoid of eye relief, and therefore force the user to keep the binoculars at the right distance with greater effort and discomfort. For this reason, we recommend not to underestimate this apparently insignificant detail.

9. Dioptric adjustment

This adjustment is often present even in the cheaper models and is important to correctly focus the image with both eyes. All have differences in sight from one eye to another, some more accentuated, some less, and it is therefore necessary to adjust the focus separately for the two eyepieces from the first use.

The diopter adjustment ring is typically located on the right eyepiece, and the procedure for adjusting the focus is very simple. We recommend checking the presence of this adjustment particularly for those who already know they have significant differences in sight between the two eyes.

10. Focus

The focus serves to visualize the object you want to observe in the clearest possible way and is achieved through a special wheel. In most cases, the focus is central, meaning that the adjustment wheel is placed between the two tubes, easily accessible by the hands holding the binoculars.

However, in some cases, the focus is independent, meaning that each eyepiece has an adjustment ring, and the focus is adjusted independently. Requiring more time than central focusing, this type of focusing is not very suitable for naturalistic observation situations, in which it is necessary to quickly focus the observed subject.

Some models also have automatic focus. These are fixed focus models in which the depth of field is such as to be able to view objects at close range up to infinity. This type of binocular is immediately ready for use without having to focus and therefore ideal for observation in the open field, particularly for marine use, or for observing fast moving subjects.

11. Interpupillary distance

The interpupillary distance is the distance between the center of one pupil and the center of the other. In order to use binoculars correctly, it is naturally necessary that the eyepieces of the instrument can align perfectly with our pupils. It is difficult to find binoculars that cannot be folded to bring the eyepieces closer or further away. However, we still recommend that you do not take anything for granted, not even details like this that may seem the most obvious.

12. Dimensions and weight

The dimensions are another very important factor to consider because they considerably affect the practicality of use of the binoculars. And the choice of this factor also depends on the type of use to be made of it. On the market you can find pocket binoculars, small and not very heavy, or larger models much more uncomfortable to carry.

Clearly the choice between these possibilities varies from person to person, but our advice is to always aim for light models, but at the same time suitable for your use. With binoculars that are too heavy, prolonged use will become difficult, not to mention transport.

13. Robustness

It is of fundamental importance that the binoculars you choose are able to withstand any exposure to the elements, possible falls and contact with dirt.

  • Waterproofing: Any binoculars worthy of the name should at least be waterproofed. Otherwise, there is a constant risk that dust or water will filter inside the instrument tubes and remain there, compromising vision. The water inside the binoculars can in fact blur the vision and once evaporated, leave halos on the lenses. The sand or earth may stick to one of the internal surfaces and in turn generate halos, or permanent dark areas on the image. Therefore, we strongly recommend that you do not buy binoculars that are not perfectly waterproof.
  • Filling: Another possible problem that can arise when using binoculars outdoors, particularly in conditions of high temperature range, is internal condensation. In air-filled binoculars this problem can often occur and is solved by waiting for the condensation formed inside the tubes to return to the gaseous state. A good instrument will be filled with gases not subject to the problem of condensation and in most cases the gas used is nitrogen. We therefore recommend checking on the technical data sheet whether the filling is anti-condensation or not.
  • Coating: Finally, it is important that binoculars to be carried outdoors can withstand external stresses, such as accidental knocks and falls. This is why, it is important that the pipes are coated with a good layer of materials capable of absorbing shocks, such as soft rubber. This material also has an important anti-slip function, which allows a good grip even when you are in the rain or if your hands are a little sweaty.

14. Accessories

Do not forget to evaluate the accessories that will be provided with the purchase of the binoculars. These can be very important for carrying, storing, and using your binoculars safely, so we recommend that you choose binoculars that have at least one accessory kit including the bare minimum:

  • Case: It can be soft, semi-rigid or rigid, and the preference depends on the use you will make of your binoculars. Better a hard case for transport inside backpacks or suitcases, while to store the binoculars in a drawer after use, a semi-rigid case may suffice.
  • Shoulder strap: Essential to always have binoculars at hand, it should ideally be comfortable. If you are not satisfied with the one supplied with the purchase, you can always buy a separate one to your taste.
  • Lens Covers: This accessory is a little rarer to find in basic supplies, but it’s very important to protect your lenses from dirt and scratches. In some models they can be attached to the binoculars by means of a cord which prevents them from being lost.
  • Cleaning kit: In most cases the standard supply includes a microfiber cloth for cleaning the lenses. You can buy solutions and tools for more thorough cleaning separately.

Other accessories are usually bought separately, as needed. For example, it may be necessary to purchase separately mounts for fixed supports, if the binoculars do not have one integrated, and a tripod, if you want to dedicate yourself to observation from a fixed position. On the other hand, for those who are mainly used outdoors, it may be interesting to get rain protection, which prevents the accumulation of water in the eyepieces.

15. Brand

On the market there are many binoculars on sale, produced by many very famous companies in the sector. The brand is not essential, but it is still a factor that guarantees the quality of the binocular and the materials with which it is made. Among the brands that produce top-of-the-range binoculars we mention Nikon, Leica and Zeiss, or Canon, Bushnell, and Vortex which, in addition to making quality products, ensure customers excellent assistance: a factor that should not be underestimated.

Frequently asked questions about binoculars

1. What are binoculars?

Binoculars are an optical instrument that allow you to observe the magnified image of a subject from a distance. They were born from the idea of creating an instrument similar to a telescope, but usable with both eyes. The first models appeared in 1645 and were nothing more than two telescopes side by side. In this way it was possible to obtain a clearer and brighter vision. The instrument underwent an evolution until 1854, when it was perfected as we know it today by the Genoese engineer Ignazio Porro.

2. What are the best binocular brands in India?

The best binocular brands in India are Nikon, Canon, Olympus, Bushnell, and Pentax.

3. What is the interpupillary distance in binoculars?

It is the distance between the center of one pupil and the other. To use the binoculars correctly, you need to be able to align the eyepieces in the best way with respect to your pupils. That’s why almost all binoculars are adjustable, allowing you to move the eyepieces closer or further away from each other depending on the distance of the user’s pupils.

4. How does focusing work in binoculars?

Focusing allows you to see an object more clearly. It is adjusted by means of a wheel usually placed in the central part of the binoculars between the two telescopes. Some binoculars offer independent focusing for each eyepiece, which has its own adjustment wheel, which is very useful especially for people who have differences or vision defects between one eye and another.

5. Can binoculars be used with glasses?

Although in general it is best to remove the glasses before using the binoculars, taking advantage of its focus to get a clear vision, people who suffer from optical disorders can still keep their glasses. But generally, it is better to unscrew the rubber shells of the eyepieces.

6. What is the best magnification for binoculars?

If you just want general purpose binoculars, 7x to 10x magnification binoculars are best. These will give you adequate magnification for most tasks and won’t be destabilized if your hand shakes slightly.

7. What do the numbers on the binoculars mean?

Binoculars are often specified by a set of numbers such as 7 × 35 or 8 × 40. The first number indicates the magnification intensity (how many times the subject is closer to you: 5 times closer, 7 times closer, 10 times closer) and the second number is the size of the lens measured in millimeters.


If before reading this practical guide you had no idea how to choose a binocular among the various types on the market, now you should no longer have any doubts!

You know the models, the features, the strengths, and you have read the reviews so now you have no more excuses, you know very well which one to choose. So don’t waste any more time and proceed with the purchase of the best binoculars in India for you.

We guarantee you won’t regret it!
