Sony alpha dslr-a500 User Manual

Sensitivity to light is expressed by the ISO number (recommended 
exposure index). The larger the number, the higher the sensitivity.

Notes
• When the exposure mode is set to AUTO or Scene Selection, ISO is fixed to AUTO 

and you cannot select other ISO numbers.

• When the exposure mode is set to P/A/S and ISO is set to [AUTO], ISO is 

automatically set between ISO 200 and ISO 1600.

• The [AUTO] setting is not provided in exposure mode M. If you change the 

exposure mode to M with the [AUTO] setting, it is switched to [200]. Set the ISO 
according to your shooting conditions.
