• Turn the rear e-dial (S) while pressing the m button to change the EV
compensation value. (p.115)
• Set the aperture value in increments of 1/3 EV or 1/2 EV. Set the exposure
steps in [1. EV Steps] in the [A Custom Setting 1] menu. (p.116)
• The proper exposure may not be obtained with the selected aperture when
the sensitivity is set to other than [AUTO] (p.90).
Exposure Warning
If the subject is too bright or too dark,
the shutter speed will blink on the status
screen and LCD panel and in the
viewfinder. When the subject is too
bright, set the aperture smaller (larger number), and when too dark,
open the aperture further (smaller number). Once blinking stops, you
can take a picture with proper exposure.
Use a commercially available ND (Neutral Density) filter if the subject
is too bright. Use a flash if it is too dark.
