Sony ILCA-99M2 - Manual (Page 285)

When using [Manual Exposure], you can perform the exposure compensation only when [ISO] is set
to [ISO AUTO].
Only a value between -3.0 EV and + 3.0 EV with the equivalent image brightness appears on the
screen when shooting. If you set an exposure beyond this range, the image brightness on the screen
does not show the effect, but it will be reflected in the recorded image.
You can adjust the exposure in a range of -2.0 EV to +2.0 EV for movies.
If you shoot a subject in extremely bright or dark conditions, or when you use the flash, you may not
be able to get a satisfactory effect.
