In a binocular power rating (e.g. 10x42) the first number is magnification. The second number is the diameter of the objective lens (large lenses at the opposite end from the eyepiece lenses), in this case 42 millimeters. Hence, 10x42. The magnification power of a 12x50 is 12 times magnification (12 times larger than n… see more In a binocular power rating (e.g. 10x42) the first number is magnification. The second number is the diameter of the objective lens (large lenses at the opposite end from the eyepiece lenses), in this case 42 millimeters. Hence, 10x42. The magnification power of a 12x50 is 12 times magnification (12 times larger than normal unaided vision). So the "zoom difference" would be an increase of 20% in the magnification from a 10x42 to a 12x50.The objective lens diameter determines light gathering capability and the size of the field of view. A higher magnification is not necessarily a good thing, as it is more difficult to maintain a stationary image, the light gathering capability is often impaired, and the field of view is reduced. For most uses, a binocular of 7 or 8 power is about right. 10 power is good for people with steady hands, and 12 power often requires a tripod to hold a stable image. see less In a binocular power rating (e.g. 10x42) the first number is magnification.

Do you? | Report These are not zoom binoculars. They are fixed at 10 power by 42mm lens and 12 power by 50mm lens. machinehead · April 4, 2017 17 people found this helpful. Do you? | Report 20%, the first number is the magnification (also called power) of the binoculars. 12x50 means the object appears 12 times larger than normal vision. 50 is the diameter of the lens, which determines how much light is let in. It is also your field of view. The larger the 2nd number the easier you can see in low light and you will see more of the landscape your viewing.
