BASIC OPERATION
•
When the camera body and lens are stored
separately, a rear lens cap attached to the back of
the lens and a body cap on the camera are
recommended.
• Avoid direct sunlight when changing lenses.
• On Canon FD lenses without an AE lock pin and
on all FL and R lenses, make sure the breech-lock
ring is turned to its full counterclockwise position
(the red dot on the ring is opposite the focusing
index mark) before mounting the lens.
