Notes
The aperture is automatically set to f/5.6
when switching to the aperture-priority AE
mode from other modes.
Be sure that the aperture value set on the dis­
play panel is between the maximum and
minimum aperture of your lens. Otherwise
exposure will be incorrect, (e g. when using
the FD 50 mm f/1.4 lens, set the aperture be­
tween f/1.4and f/22.)
