Shooting Hard-to-Focus Subjects
(Focus Lock)
Shooting Mode
1
Aim the camera so that an object at the
same focal distance as the main subject is
centered in the viewfinder or in the AF frame
displayed on the LCD monitor.
2
Press the shutter button halfway to lock the
focus.
3
Keep the shutter button pressed halfway
while you recompose the image and press
the shutter button all the way to shoot the
image.
z When the focus lock is set and the LCD monitor is used to
shoot, setting AiAF to [Off]
(p. 35) makes shooting easier
since the camera focuses using the center AF frame only.
z The AF frame will not appear in mode.
