NOTICE:
With TTL flash photography, the
reflection of the flash is metered
and the intensity of the flash is
adjusted automatically, so TTL flash
photography may not be able to
suit to all conditions. In the cases
described below, we recommend
that you use a flashmeter to check
the intensity of the flash or to use a
manual flash setting.
