EXPOSURE SETTING
The camera offers two exposure modes: Aperture priority mode or
manual setting. Choose one of the two options depending on
image subject, situation or individual preference.
APERTURE PRIORITY MODE A
When the shutter speed setting wheel is in the
A
position, the
camera electronics will calculate the correct shutter speed
automatically and steplessly in the range between 1⁄4000 s and
4 min (max. exposure time available only for ISO 100/200). The
setting is calculated in accordance with the set sensitivity, metered
brightness and the manually selected aperture. The resulting
shutter speed is displayed in half increments for more transparen-
cy.
The remaining exposure time after shutter release is counted down
in seconds on the display for shutter speeds greater than 2 s. The
actual calculated and steplessly controlled exposure time may vary
from the exposure time displayed in half step increments: if e.g.
the display shows
16
(the closest value) before shutter release, but
the calculated exposure time is longer, then the countdown after
shutter release can start from
19
. Under extreme lighting condi-
tions and based on all the parameters, the exposure meter may
generate a shutter speed that is outside the working range, i.e.
brightness values that would require shorter exposures than
1⁄4000 s or longer than 4 min. If that is the case, then the camera
will use the stated min. or max. shutter speeds and these values
will flash as a warning in the viewfinder.
Notes
• Image noise becomes apparent when using higher sensitivities,
particularly on uniform dark areas. In order to reduce this
annoying phenomenon, the camera will take a second “black
picture” (taken with the shutter closed) automatically after
pictures taken with slow shutter speeds and high ISO values. The
noise metered in this parallel picture is then digitally “subtract-
ed” from the data for the actual picture. As a result, the
message
Noise reduction
will appear in the display for
12s
1
. The
doubling of the “exposure” time must be taken into account for
long exposure times. The camera must not be switched off
during that time.
• When the
B
function is selected in conjunction with auto shutter
release (see S. 77), then the shutter button doesn’t have to
be held down and the shutter will remain open until the shutter
button is pressed again (the equivalent of a
T
function).
