Magnification is also sometimes called the power of the binoculars â binoculars labeled as 8-power have eight times magnification. Most optics have clearly labeled magnification, usually on the large focus wheel between the two long barrels of the binns.
Binoculars are often specified by a set of numbers such as 7Ã35 or 8Ã40, the first number indicates the strength of magnification (how many times closer the subject is to you, 5 times closer, 7 times closer, 10 times closer) and the second number is the size of the objective lens measured in millimeters going across the lens.
