When Autofocus Fails (Manual Focusing)
48

Manual Focusing

1Set the lens focus mode switch to
MF (or M on older lenses).
•The AF mode indicator on the LCD
panel turns off.
2Focus by turning the lens
focusing ring until the subject is
in focus in the viewfinder.
•Select the desired focusing point and press the shutter button halfway while
manual focusing. When focus is achieved, the selected focusing point will flash
and the in-focus indicator will light.
•When the focusing point is selected automatically and the center focusing point
achieves focus, it will flash and the in-focus indicator will light.
•With USM (Ultrasonic Motor) lenses (except those not having a distance
scale), you can use the focusing ring to fine focus after focus is achieved in the
One-Shot AF mode (full-time manual focusing).
For USM lenses with an electronic focusing ring (such as the EF 200mm
f/1.8L), Custom Function C.Fn-7 can require the lens focus mode switch to be
set to MF(or M) before manual focus is enabled. (→p.102)
