“Camera shake” refers to unwanted movement of the camera that occurs after the shutter button has been pressed, resulting in a blurred image. To reduce camera shake, follow the instructions below.
1. Correct posture
Stabilize your upper body and take a position that keeps the camera from moving.

Camera shake warning indicator
Due to potential camera shake, the (Camera shake warning) indicator flashes. In this case, use a tripod or the flash.
Note : The (Camera shake warning) indicator is displayed only in the modes that automatically set the shutter speed. This indicator is not displayed in M/S modes.
2. Using the SteadyShot function
This SteadyShot function can reduce the effect of camera shake by the equivalent of approximately 2.5 to 3.5 increments of shutter speed. The SteadyShot function is set to [On] in the default setting.
The SteadyShot scale indicator
The (SteadyShot scale) indicator shows the camera shake status. Wait until the scale becomes low, then start shooting.
Note : The SteadyShot function may not work optimally when the power has just been turned on or when the shutter button has been pressed all the way down without stopping halfway. Wait for the (SteadyShot scale) indicator scale to go down, and then press the shutter button down slowly
3. Using a tripod
In the following cases, we recommend that you mount the camera on a tripod.
Note : When using a tripod, deactivate the SteadyShot function because there is a potential for malfunction of the SteadyShot function
The “AUTO” mode allows you to easily shoot any subject under any conditions because the camera makes appropriate judgments on the situation to adjust the settings. Select when shooting in a location where the use of a flash is restricted. When you turn the mode dial, the explanation of the selected mode and methods of shooting are displayed on the screen (Help Guide disp.). You can clear the Help Guide

Sensitivity to light is expressed by the ISO number (recommended exposure index). The larger the number, the higher the sensitivity.
Notes
The color tone of the subject changes depending on the characteristics of the light source. The table below shows how the color tone changes based on various light sources, compared with a subject that appears white under the sunlight.

White balance is a feature that adjusts the color tone to approximate what you see. Use this feature when the color tone of the image did not come out as you expected, or when you want to change the color tone on purpose for photographic expression.
Notes
Adjusting the white balance to suit a specific light source (Auto/Preset white balance)
Fn button t [White balance] t Select the desired setting

Registering the color tones (Custom white balance)
In a scene where the ambient light consists of multiple types of light source, use of custom white balance is recommended in order to accurately reproduce the whiteness.
To call the custom white balance setting
Fn button -> [White balance] -> (Custom)
Note : If the flash is used when the shutter button is pressed, a custom white balance is registered with the flash light taken into account. Take pictures with the flash in later shootings.
