There is a magic number to convert the angle field of view to linear field of view and that is 52.5. Therefore a 7×35 binocular will have a wider field of view than a 10×50 one. While the field of view is affected by magnification, it is usually in relation to the objective lens size. This raises the question of what does 10×50 means in binoculars, especially in relation to the field of view. For hunting 350 to 400 Fov is quite enough. Therefore, higher magnification will result in a narrower field of view. What is important to note is that the field of view is affected by increased magnification. The higher the field of view the wider you can see the surroundings. But Field of view is not expressed as Degrees rather they are expressed as feet per 1000 yards or feet per 1000 meters. The field of view is the same as the angle of view. That means an angle of view of 7.2 degrees translates to a 378 field of view. This is done by multiplying the angle of view by 52.5. It is possible to convert the angle of view to the field of view. A field of view of 300 to 375 is sufficient for most people. A higher number means you have a wider horizontal view. On the other hand, the field of view is indicated in feet per 1000 yards or meters per 1000 yards. For example, if a binocular has a 10x magnification and an angle of view of 7.2 will have an actual angle of view of 72 degrees. However, this is usually the actual angle of view and is obtained by multiplying the magnification with the angle of view. For example, most of the best binoculars under 200 will have an angle of view of 6 degrees, while some will have a high number, such as 72 degrees indicated. These two numbers refer to the amount of horizontal area that is visible through binoculars. The angle of view is usually indicated in degrees. The binocular numbers definition for these two numbers is mostly the same. The next two numbers you are likely to notice printed on binoculars are for the angle of view and field of view. This is because a wide objective lens increases the weight of the entire binoculars. As such, a 10×50 binocular will be better for nighttime viewing than a 7×35 one.Īlso, a larger objective lens means more shakiness in the image. Also, a wider objective lens means more light passing through it. The wider that lens, the heavier the binocular. Now you may ask what does binoculars 10×50 mean? Therefore, a 10×50 binocular has an objective lens with a 50mm diameter. The objective lens is located on the other side of the eyepiece you use to look through the binocular. The second number that follows the magnification denotes the binoculars’ objective lens size. For that, you can buy zoom binoculars which will allow you to play with the adjustable magnification range. However, for spotting things 3km or more away, you will need a higher magnification of about 16x or 20x. So how far can you see with 10×50 binoculars? A 10x magnification will be sufficient for observing objects about 2KM away. The solution is stabilizing the binocular on something stable, such as a tripod. Of worth noting is that a high magnification of 12x and over makes it difficult to maintain a steady image. That means a 12x binocular will make objects appear closer than a 10x one. The higher the number, the nearer objects will appear. As such, a 10x binocular can make an object appear ten times closer than it is. The first number refers to a binoculars’ magnification level. This number is representative of a binoculars’ two most important features, magnification and objective lens. What Do The Numbers On Binoculars Mean?.
