What is meant by 8×42 Binoculars?
8×42 is simply a configuration of a pair of binoculars. The two numbers represent two separate performance measures. The first number refers to the magnification power and the second refers to the objective lens diameter.
This means that in an 8×42 binocular, 8 refers to 8 times magnification power i.e. the binoculars can make the image appear 8 times larger than its actual size.
The second number 42 refers to the diameter of an objective lens which is an essential parameter in determining the amount of light that is allowed to pass through the lens and enter your eyes.
The 8×42 configuration of a binocular is sometimes considered to be the universal configuration because it is practical and adequate for all types of situations. Sometimes, 10×42 is also considered a standard configuration because it provides a wider field of view.
What to look for in 8×42 Binoculars?
Binoculars are very carefully calibrated pieces of equipment. A lot of money is involved in purchasing one of these optical devices. Thus, before you make a purchase, it is important to know all that you can about the device. There are certain factors that you can look into and learn about before purchasing a binocular.
In the following segment, we will be looking into some technical terms and contributing factors.
This is a simple term and needs no real explanation. Magnification refers to the capability of the device to enlarge the size of the projected image. The magnification is given in numbers. For example, 10x magnification means the projected image will be 10 times the size of the original object. 8x magnification is also a fairly good magnification power. However, large magnification is known to have bad performance in low lighting and also tends to blur the image.
When the reflected light from an object enters our eyes, we are able to visualize things. The more light that enters, the better you can see. The objective lens is the first lens which lets the light enter the scope and its size decides the amount of light allowed to enter. Since more light means a better image, a large objective lens is preferred by people. A large sense does affect the weight of the binocular.
Exit pupil is on the user end of the binocular. It is the part of the binocular which acts as a gateway from which the image enters the eye of the user. It is ideal for all the light exiting the binocular to enter our eye. This is only made possible if the aperture of the exit pupil is small enough to focus all of the light into our eyes. When looking for a binocular, go for a small exit pupil.
Field of View
The more you can see from the binocular the better. Field of view is the amount of area that is visible when you look out of a binocular. The field of view is generally given in the terms of degrees is displayed on either side of the viewer. A large field of view is always a good thing as you can view a large area with just one position setting. A small field of view will cause you to move around and adjust your position continuously.
Eye relief refers to the distance between the user’s eyes and the exit pupil. This distance is generally calibrated based on where will the exit pupil display will project the final image. It is advisable to go for a movable eye relief rather than a fixed eye relief. This way, you have a range of adjustments that you can make. Also, go for a silicone covering over the relief for ease of use and longer viewing time.
Lenses are made of glass which, by its property, reflects back some of the entering light. This reflected light tends to cancel out the entering light, disrupting the picture quality. In order to avoid such distortions, the lenses are coated to reduce reflection. The coatings are also made of substances which help reduce optical disruptions.
Weight and Durability
A binocular is a bulky instrument, especially if it’s very powerful. The large size of the objective lens and the material used to build it add to the weight. Since a binocular is mostly an outdoor device, it is important to make it durable. It is integral that durable material is used to create your binocular. This factor will make sure that you get to use the binocular for a long period of time. In order to compensate for the weight, a tripod is advisable.
