When looking at specifications for a digital camera, both the optical
and digital zoom measurements are listed as a number and an "X," such
as 3X or 10X. A larger number signifies a stronger magnification
capability.
Keep in mind that not every camera's "10X" optical zoom measurement is the same. Manufacturers measure the optical zoom from one extreme of the lens' capabilities to the other. In other words, the "multiplier" is the difference between the smallest and largest magnification measurements of the lens. For example, if a 10X optical zoom lens on a digital camera has a minimum magnification equivalent to 35mm, the camera would have a 350mm maximum zoom. However, if the digital camera offers some additional wide-angle capabilities and has a minimum 28mm equivalency, then the 10X optical zoom would only have a maximum zoom of 280mm.
The zoom range should be listed in the camera's specifications, usually in a format similar to "35mm film equivalent: 28mm-280mm.” In most cases, a 50mm lens measurement is considered as "normal," with no magnification and no wide-angle capability.
