FOCUSING (AUTOFOCUS)

focus mode selector dial, set the focus mode to “S” or “C”, and then set the AF/MF
switch on the lens side to “AF”. Press the shutter button lightly while viewing through the
camera’s viewfinder. The lens focuses automatically. An in-focus mark will light when
lens focuses on the main subject sharply. Press the shutter button further to photograph.
* When set on AF mode, interfering with the focusing ring may cause serious damage to
the lens mechanism.
* The distance scale is marked for guidance purposes. The actual focal point may slightly
differ from the distance marked on the focal length index.
FOCUSING (MANUAL FOCUS)

focus mode selector dial, set the focus mode to “M”, and then set the AF/MF switch on
the lens side to “MF”. Focus manually by rotating the focusing ring while viewing
through the camera’s viewfinder. The main subject in the viewfinder will be sharp when
the lens id focused correctly.
* Even when in MF mode, turning the focusing ring while pressing the shutter button
halfway, the focus aid function lamp lights up when the picture is in focus.
* At infinity, make sure the image in the viewfinder appears sharp. The infinity position
is made with certain allowances to insure proper focus under a variety of conditions.

VC Mechanism
VC (Vibration Compensation) is a mechanism which reduces the image blur caused by
hand-held shooting. When using the VC, pictures can be taken at shutter speeds up to a
maximum of 4 stops slower than the speed when the VC is not used.
