When buying a pair of binoculars you will soon notice that each pair has a set of two numbers following their name, such as “7x50” or “8x32”. The first figure is the magnification, which indicates the number of times larger an object will appear when viewed. The second figure indicates the size of the object lens in mm; the larger it is, the brighter the images will seem. View our Binoculars Buying Guide for more information »
