[QUOTE="Bob Blaylock, post: 605486, member: 16749"] The first number is the magnification factor, and the second is the diameter, in millimeters, of the objective lens. 8×42 would mean that the binoculars have a magnification of 8 times, and that the objective lenses are 42 millimeters in diameter. Higher magnification is good, up to the point where it becomes difficult to hold it still enough to see clearly. I think 10× is considered a practical upper limit for most people, for handheld binoculars. Larger objective lenses mean a brighter image, and possibly a wider field of view. Think of it as being somewhat related to the ƒ/ number of a camera lens. [/QUOTE]
