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.
ZOOM (or variable power) binoculars, allow you to increase the magnification of the image you are looking at by a variable amount indicated by the first 2 numbers separated by a hyphen. For example: The magnification range for 7-21x50 is 7 times up to 21 times magnification.
