Best Pair of Binoculars

If you are a nature lover and often prefers to go for sight-seeing or bird watching, then surely you would be requiring a handsome pair of binoculars so that you may be able to observe the finest of details, identifying colors from shadows and enhance your identification skills. Although binoculars are considered to be expensive, still you can add a little more amount to your budget so as to choose the best pair of binoculars as per your requirements. Let us look at some of the essential things that you must consider while going to buy the best pair of binoculars for you which are mentioned below:

1. The size of the binoculars

There are multiple options for the availability of different sizes in the market which you may compare. There are mainly three varieties –

  • Full-size binoculars are most commonly used for those who are wildlife observers and also for those who spend most of their times on boats. This type helps to view thing under lower illumination and also captures the larger amount of light. The view is much wider and the best for seeing birds. The only limitation is that it is bulky and difficult to carry in a bag pack.
  • Midsize binoculars are most commonly used for the sports purposes as well as for wildlife viewing. These are able to transmit light higher than average levels. These are also a little bulkier to carry.
  • The compact binoculars are the best choice for carrying out outdoor activities during daytime but these are not the best choices for the long-term use.

2. Magnification power of binoculars

There are two numbers by which you can identify the binoculars. These numbers are a display of their magnifying power and the diameter of the lens. For instance, a binocular has a magnification power of 8 if there are 8 x 40 binoculars.

The magnification power 8 refers to the fact that the objects would appear 8 times nearer as compared to that of the neutral eye without any binoculars. One should note the fact that those binoculars who possess greater than 10 magnifying power, these can make the view in a steady position difficult because of the causation of hand movements.

3. The diameter of the lens of binoculars

The second number present on the binoculars displays the diameter of the lenses used in binoculars. The diameter is measured in millimeters. For instance, 8 x 40 binoculars contain the objective lenses of 40mm.

The diameter of the lens is the measure of the amount of light that can be gathered by the binoculars. It is one of the differential criterion as the two binoculars having exactly similar specifications other than the lens diameter determine the amount of light captured by the binocular. Larger the diameter of the objective lens, greater would be the light capturing ability. The greater amount of light gathering means a brighter view.

4. The exit pupil of the binoculars

Exit pupil refers to a number that is an indicator of the brightness hold by an object under lower illumination. Higher is the exit pupil number, greater will be the brightness. Even during your hand movements or shakiness, the large exit pupil would enable you to observe a complete image of the concerned object. You may also check the best low light binoculars online.

Exit pupil size can be determined by the number which is obtained by dividing the lens diameter to the magnification power of the binoculars.

5. Consider the eye relief

Eye relief is determined by the distance present between eyes and the eyepiece lens of the binocular when you are able to see the complete field view. Eye relief for a longer period of time would provide comfort and aids in holding your binoculars at a little distance from your face.

6. Waterproof binoculars should be your preference

What if you go out on a rainy day, then surely you would need the binoculars that are resistant to weather conditions. Those binoculars that contain O rings are able to prevent entry of moisture and will also help in obstructing the dust to get in.


Therefore, you must take care of the above-mentioned things while choosing a pair of binoculars. Your requirements, as well as the budget, would determine your selection.
