The built-in flash and vignetting
• The built-in flash cannot be used over distances
of less than 0.6 m (2.0 ft.).
To prevent vignetting, do not use the lens hood.
Vignetting is the darkening of the corners around
the image that occurs when the light emitted by
the flash is obstructed by the lens barrel.

Focusing, zooming, and depth of
field
Before focusing, rotate the zoom ring to adjust the
focal length until the desired composition is
framed. If your camera has a depth-of-field
preview (stopdown) button or lever, depth of field
can be previewed through the camera viewfinder.
• This lens is equipped with the Internal Focusing
(IF) system. As the shooting distance decreases,
the focal length also decreases.
• The distance scale does not indicate the precise
distance between the subject and the camera.
Values are approximate and should be used only
as a general guide. When shooting distant
landscapes, depth of field may influence
operation and the subject may appear in focus
at a position that is closer than infinity.
• For more information, see p. 146.
Setting the aperture
Use the camera to adjust the aperture setting.
