2. Depress the shutter release button fully, and the
flash unit discharges. After using the flash, retract
the built-in flash by pressing it down into the camera
body.
• If the Built-In flash is used continuously, the battery
may become warm, but it does not mean the battery
is faulty; it is one of the battery's characteristics.
• With the Built-in flash popped-up, an External Flash
cannot be attached to the hot shoe. If you would like
to use an external flash together with the Built-in
flash, see the flash connections on page 76.
• The shutter cannot be released until the flash is fully
charged.
Flash effective range for Programmed TTL Auto Flash

approx. 0.8 - 3.9m (0.8- 5.6m)

2.3-9.2ft (2.3-13.1 ft)
f/3.5.f/4.7
approx. 0.7 - 2.4m (0.7- 4.0m)
2.3-7.9ft (2.3-13.1 ft)
f/5.6
approx. 0.7 - 2.0m (0.7- 4.0m)
2.3-6.6ft (2.3-13.1ft)
The effective range of the flash depends on the maxi¬
mum aperture of the lens in use. A lens with a maximum
aperture of f/1.4 is marked as 1:1.4 on its barrel.
• This effective range table is only applicable when the
exposure mode is set at the Programmed AE Mode.
When any other exposure mode is used, see page 72.
• The minimum effective range is always 0-7m (2.6ft)
even if a lens with a maximum aperture f/2.8 or
smaller is in use. When a subject is shot at a distance
closer than 0.7m (2.6ft), the correct exposure cannot
be obtained, and you will see vignetting in the picture
corners.
