Aperture, Sensitivity, and Flash Range
The range
of
the built-in flash varies
with
sensitivity
(ISO
equivalency)
and aperture.

The built-in flash
has
a
minimum
range
of
0.6 m
(2
ft.).
In
programmed auto exposure
mode
(mode
P),
the
maximum aperture
(minimum
f-number)
is
limited according
to
ISO
sensitivity,
as
shown
below:
200

aperture
at

For
each one-step increase in sensitivity
(e.g.,
from 200
to
400), aperture
is
stopped
down
by half
an
f-stop.
If
the
maximum aperture
of
the
lens
is
smaller than given above, the maximum value for aperture will be
the
maximum aperture
of
the
lens.
