The larger the ISO value, the darker the location in which you can shoot. However, increasing 
the ISO value leads to increased noise (graininess) in the picture. ISO200, which gives 
optimal noise and gradation balance, is recommended for normal use.
For a slower shutter speed or when you want to open the aperture, use ISO100.

: The sensitivity is set automatically 

according to the shooting conditions. For 
[ISO-AUTO SET], you can set the default 
(value normally used when the optimal 
exposure can be obtained) and upper 
limit (upper limit of ISO that automatically 
changes).

: Fixed ISO sensitivity [ISO STEP] can be 

changed to 1/3 EV or 1EV increments.
