Exposure warnings
With an inappropriate exposure setting, when shooting subjects that are too light or
dark, the user is warned by the flashing external LCD or the LCD inside the viewfinder.
At such times, the correct exposure cannot be obtained.

Important
When a polarizing filter is used, ensure that a circular polarizing filter
(circular filter: C-PL) is used. The correct exposure cannot be obtained
with a normal polarizing filter (PL).
Exposure compensation is also possible during AE lock.
The shutter speed changes with exposure compensation in manual mode ("M").
1. When exposure compensation button is
pressed, appears on the external LCD.
When the front or rear dial is turned
counterclockwise, the exposure is increased;
conversely, when it is turned clockwise, it is
decreased. The exposure compensation value
can be checked on the external LCD or LCD
inside the viewfinder.
2. After taking the pictures, press exposure
compensation button again to return the
exposure compensation value to 0.
The exposure compensation value mark on the
external LCD is cleared, and the exposure
compensation function is released.
(When a Metz flash is not equipped.)
In some situations, such as a great difference between the subject and background
brightness or overall subject tones that will not meter correctly because they are all
black or white, the resulting photograph may be under- or overexposed. When this
occurs, use the exposure compensation function. Exposure compensation can also be
used when you want to intentionally create overexposed or underexposed pictures.

The width of the exposure compensation step can be changed.
