# Cautions
• In [ !/#!(Red-eye reduction fl ash)], after the pre-fl ashes, it takes about 1 second
before the shutter is released. Do not move the camera until shooting is complete.
• [ !/#!(Red-eye reduction fl ash)] may not work effectively under some shooting
conditions.
• When the fl ash fi res, the shutter speed is set to 1/320 sec. or slower. When shooting
a subject against a bright background with the fi ll-in fl ash, the background may be
overexposed.

Minimum range
The lens may cast shadows over objects close to
the camera, causing vignetting, or be too bright
even at minimum output.
Lens
Approximate distance at
which vignetting occurs
14 – 42 mm 0.25 m
17 mm 0.25 m
40 – 150 mm 0.9 m
14 – 150 mm 0.5 m
12 – 50 mm 0.45 m
12 – 40 mm
3.2 m (when focal length is
12 mm)
0.7 m (when focal length is
14 mm or above)
• External fl ash units can be used to prevent vignetting. To prevent photographs from being
overexposed, select mode A or M and choose a high f-number, or reduce ISO sensitivity.
