Using an External Flash

Use of a commercially available flash unit makes it possible
to obtain a higher level of brightness (guide number) than
you get when using the built-in flash alone. An external flash
also makes it possible to extend the effective range of flash
photography.
• The guide number of the internal flash is 6.5 (ISO 100/m).

External Flash Unit Requirements

Any external flash unit you use with this camera must satisfy
the following requirements.
• Variable flash intensity (AUTO)
• Flash Duration: Less than 1/1000 sec.
• Coverage Angle: Coverage of 33mm equivalent 35mm fo-
cal length lens (without wide conversion lens)
IMPORTANT!
• Some flash performance may be lost when using a
ring flash or other type of unit with a long flash time.
• The aperture values and ISO sensitivity available with
some flash units may not match the values supported
by your camera. In such a case, make adjustments in
the aperture setting of the external flash and the cam-
era until proper brightness is achieved.
