And remember that digital cameras generally have an abundance of ???reach?????”it??™s pretty easy for
manufacturers to make digital cameras with long zoom lenses. What??™s harder is making wide
angle lenses, so you might find it more difficult to locate cameras with a wide bottom end on the
zoom range. And trust me: you will probably want to go wide more often than you??™ll want to go
long, especially for indoor photography.
Choose a Zoom
A zoom lens lets you change the focal length of the camera. In simple terms, it lets you choose
how much the camera magnifies the image, and zoom lenses let you zoom in and out of a scene
for the perfect composition. In general, the greater the zoom, the better. You??™ll commonly see 2x,
3x, and perhaps even 5x zooms on digital cameras. With some simple finger pressure, you can
use your camera to go from a normal or wide-angle view to telephoto. The effect of a 4x zoom is
apparent in Figure 1-6, taken at both ends of a camera??™s zoom range.

12 How to Do Everything: Digital Camera
Beware, though, of a camera??™s digital zoom. While optical zooms move the lenses around to
actually magnify the image, a digital zoom simply grabs a block of pixels in the middle of the
scene and processes them to make the image look bigger.
