Locking the ISO value (ISO setting)
•
The ISO settings are based on the film speeds used in conventional
photography and are only intended as a guide.
•
If you select "AUTO" and then set the Mode dial to "A/S/M", the ISO value
is set to 100.
•
When you select "AUTO", the camera automatically selects a higher
ISO setting if you take a shot in low-light conditions without the flash.
This is to prevent blurring due to camera shake.
•
Higher ISO settings give increased graininess (noise) in the image.
•
Unless you select "OFF" in the "ALL RESET" setting (P.173), this setting will
be cancelled when you switch the camera off.
