Zoom lenses always have two focal lengths specified, for example 18-55 mm, indicating the zoom range of the lens. If you want this translated into compact camera language, you can just divide the largest number by the smallest, which in the 18–55 mm case gives a zoom of about 3x.

What F stop is sharpest?
The sharpest aperture of your lens, known as the sweet spot, is located two to three f/stops from the widest aperture. Therefore, the sharpest aperture on my 16-35mm f/4 is between f/8 and f/11. A faster lens, such as the 14-24mm f/2.8, has a sweet spot between f/5.6 and f/8.

Simply put: how sharp or blurry is the area behind your subject. The lower the f/stop—the larger the opening in the lens—the less depth of field—the blurrier the background. The higher the f/stop—the smaller the opening in the lens—the greater the depth of field—the sharper the background.
