You may have noticed two numbers printed on the body when looking at a pair of binoculars. Have you ever wondered what these numbers mean? Read on to better understand these figures and how they can help you pick the perfect pair of binoculars for your needs.
The numbers on binoculars indicate the magnification and size of the objective lens. For example, if you purchase a pair with 8×42 written on them, it means that when viewing an object through them, it will appear eight times closer than with the naked eye, and each lens has a diameter of 42 millimeters. This is important when selecting larger objective lenses that let in more light, resulting in brighter images and more clarity, even in low-light conditions.
Higher magnifications, such as 10×50 or 12×56, can provide greater detail when viewing distant objects. However, they are only appropriate for some situations because they can reduce your field of view and make it difficult to track moving targets. As such, lower magnification, such as 7×35 or 8×42, may be better suited to casual or everyday use where image detail isn’t so crucial or working with children who need less magnification.
In addition to providing information on its magnification capabilities, knowing the size of the objective lenses is also helpful when assessing whether they are suitable for any additional accessories, such as filters or tripod mounts which may require specific sizes. It is also important to remember that although larger lenses let in more light and result in brighter images, they can also make binoculars heavier — something worth bearing in mind if planning extended periods of use!
Take Away:
Understanding the two numbers printed on binoculars can help guide you toward making an informed decision about which binocular is right for you, whether you want enhanced image detail from further distances or something smaller and lighter for casual use. With this knowledge now, why not go out there today and explore all that lies before you?
