The memory lock function enables an exposure level to
be memorized before shooting. The memory lock func­

exposure when the subject occupies only a small part of
the viewfinder.

pressed. a 10 second timer starts and the camera
stores the measured exposure level until the time ex­
pires. The memory lock function remains while the
momory lock button is depressed.
• If the shutter button is depressed halfway down while
the memory lock timer is operating, the memorized
meter reading will remain even if the memory lock
button is released.
• During memory lock operation. [ * ] is displayed in

ory lock button is depressed.

ory lock button [ ML ] again.
