FE Lock
When used with Type A cam-
eras, the Speedlite 220EX
enables FE (Flash Exposure)
lock which locks the flash expo-
sure reading for the desired
area. Use FE lock to obtain and
lock the correct flash exposure
reading for the desired area of
the picture. You can simply
recompose the shot while retain-
ing the flash exposure reading
for optimum flash exposure.
• Use of FE lock may not provide the desired results when locking the
flash exposure reading of a relatively small subject.
• Use of FE lock is not applicable for flash photography with fully-auto-
matic flash operations.
+/–
Set the camera to the
desired Creative Zone
mode (P, Tv, Av, M, or
DEP).
Press the shutter button
halfway to focus on the
subject. Keep pressing
the shutter button halfway
even after focus is
achieved.
Aim the focusing point
where you want to obtain
correct flash exposure
reading, then press the FE
lock button.
• The preflash is fired to obtain an
initial flash exposure reading
which is used to compute the
output of the main flash for opti-
mum flash exposures.
• The FE lock symbol (FEL) is dis-
played in the viewfinder for about
0.5 sec. and the correctflash
exposure reading is locked.
• The correct flash exposure read-
ing that is obtained is locked for
16 sec. after the FE lock button
is released.
