Under certain types of conditions, the auto focus may not work properly.
In these cases, focus (focus lock) on an object with high contrast at the same
distance as the intended subject, recompose your shot and then take the picture.
If the subject has no vertical lines, hold the camera vertically and focus the camera
using the focus lock function by pressing the shutter button halfway, then return the
camera to the horizontal position while keeping the button pressed halfway and take
the picture.
TIPS
To focus on the subject in the center of the frame
g“AF mode (iESP/SPOT/AREA)” (P. 57)
When the frame in which you focus on a subject is different from the
frame in which you lock the exposure
g“AE lock” (P. 61)
To fix the focus
g“AF lock” (P. 59)
Note
• Press the shutter button gently. If it is pressed forcefully, the camera may move
causing the picture to blur.
• Never remove the batteries or disconnect the AC adapter while the orange
lamp on the side of the viewfinder is blinking. Doing so could destroy stored
pictures and prevent storage of pictures you have just taken.
• Recorded pictures are saved in the camera regardless of whether the camera
is turned off or the batteries are replaced or removed.
• When taking pictures against strong backlight, the area of the picture in shadow
may appear colored.
• When a conversion lens is attached to the camera, the edges of the picture may
appear dark. Check the recorded image on the monitor.
