Exposure

Noise in images

During shooting at slow shutter speeds, noise may appear on-screen. These phenomena are

caused when current is generated in those sections of the image pickup device that are not

normally exposed to light, resulting in a rise in temperature in the image pickup device or image

pickup device drive circuit. This can also occur when shooting with a high ISO setting in a high-

temperature environment. To reduce this noise, the camera activates the noise reduction

function.

The use of a monopod or tripod is recommended when taking a picture at slow shutter speed.

To switch the operation between setting the shutter speed and aperture value:

You can set the aperture value using only the control dial.
