With [Enable], the Auto Lighting Optimizer (p.140) is automatically set to [Disable] and the setting cannot be changed. When [Highlight tone priority] is set to [Disable], the Auto Lighting Optimizer will revert to its original setting.
With [Enable], image noise (graininess and banding, etc.) may increase slightly more than with [Disable].
With [Enable], the settable range will be ISO 200 - ISO 12800 (up to ISO 6400 for movies). Also, the <A> icon will be displayed in the viewfinder and on the LCD panel when highlight tone priority is enabled.
