Chapter 1: Getting the Lay of the Land
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
The kit lens (and some other Micro Four Thirds lenses) sports the features
shown in Figure 1-7. Get familiar with the following key components:
Unlock switch
Focusing ring
Focal length indicator
Zoom barrel

✓
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).
