Always attach and remove lenses in a clean environment to reduce the risk of
getting dust, dirt, and other contaminants inside the camera or lens. For
added safety, point the camera body slightly down when performing this
maneuver; doing so helps prevent any flotsam in the air from being drawn
into the camera by gravity.
Familiarizing yourself with the lens

shown in Figure 1-7. Get familiar with the following key components:

Zoom barrel: If you own a zoom lens (such as the kit lens), zoom in and
out by simply twisting the zoom barrel.
Focal length indicator: Every lens can be characterized by its focal
length, measured in millimeters. The focal length determines the angle
of view (the area the lens can capture), the relative size of objects in the
frame, and the depth of field (the distance over which objects remain
sharply focused).
