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. 

g“Noise reduction” (P. 69)

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

j When the shutter speed is slow, camera shake is more likely to occur. You can reduce camera 

shake by using the image stabilizer. 

g“Image stabilizer” (P. 60)
