Taking Pictures Using the Shake
Reduction Function
You can easily take sharp pictures using the Shake Reduction function by
simply turning on the Shake Reduction switch.
Shake Reduction
The Shake Reduction function reduces camera shake that occurs
when the shutter release button is pressed. This is useful for taking
pictures in situations where camera shake is likely to occur. The Shake
Reduction function allows you to take pictures at approximately 4 steps
slower shutter speed without the risk of the camera shake.
The Shake Reduction function is ideal when taking pictures in the
following situations.
• When taking pictures in dimly lit locations, such as indoors, at night,
on cloudy days and in the shade
• When taking telephoto pictures
Shake Reduction Function and Lens Focal Length
The Shake Reduction function operates by acquiring the lens information
such as focal length.
If the camera uses a DA, D FA, FA J, FA or F lens, the lens information is
automatically acquired when the Shake Reduction function is activated.
[Focal Length] cannot be set from [Input Focal Length] menu in the [A
Rec. Mode] (The menu items cannot be selected).
If another type of lens is used, the lens information cannot be automatically
acquired even when the Shake Reduction function is activated.
In this case, the [Input Focal Length] setting menu appears. Set [Focal
Length] manually on the [Input Focal Length] setting menu. 1 Setting the
Shake Reduction Function (p.67)
• The Shake Reduction function does not compensate for blurring caused by movement
of the subject. To take pictures of a moving subject, increase the shutter speed.
• The Shake Reduction function may not fully reduce camera shake when
taking close-up shots. In this case, it is recommended that the Shake
Reduction function be turned off and the camera be used with a tripod.
• The Shake Reduction function will not fully work when shooting with a
slower shutter speed, for example when shooting a moving subject or
night scenes. In this case, it is recommended that the Shake Reduction
function be turned off and the camera be used with a tripod.
