AUTOMATIC PROGRAM – P
The automatic program mode facilitates fast and fully automatic
photography. The exposure is controlled by an automatic shutter speed
and aperture setting. Exposure time and lens aperture are automatically
set according to the prevailing light and steplessly between 125 s and
1⁄4000 s, when using the central shutter on some Leica S lenses, and
between open and smallest aperture of the respective lens.
Displays
–
P P
for the selected exposure mode
– the automatically controlled shutter speed and exposure values
Notes
• If the automatic sensitivity setting (
AUTO ISO AUTO ISO
) is activated at the same
time, the control range of automatic program mode is extended. Even
with fully open aperture, however, the shutter speed is only extended
beyond the value dictated by the
1/f 1/f
1 setting selected in the menu
when the highest set sensitivity is reached.
• With very little light or extreme brightness it is possible that the
available shutter speed range is no longer sufficient for the preselected
exposure value. In such (extremely rare) cases, a warning icon for
underexposure or overexposure will appear in the viewfinder (or a
warning message regarding values below the measuring range).
Correct exposure metering will then be rendered impossible.

PROGRAM SHIFT
▸ Press and hold the thumbwheel (≥ 1 s)
▸ Turn the thumbwheel
▸ Select
P P
The program shift function allows the speed/aperture combinations
determined in automatic program mode to be changed, while the overall
exposure, i.e. the brightness of the image, remains unchanged.
Shifting is done via the shutter speed setting wheel.
– for larger apertures (smaller values) or faster shutter speeds.
▸ turn to the right
– for smaller apertures (larger values) or slower shutter speeds.
▸ turn to the left
Displays
–
S S
in the top display to indicate the use of the program shift function
– the mode display
P P
in the LCD panel changes to
PS PS
– the automatically controlled aperture and shutter speed values change
inversely
Note
Program shift settings are maintained:
– after a photo is taken
– beyond the 12 s holding time of the exposure metering system, but not
when switching to another exposure mode (
A A
,
T T
,
M M
) and when switching
the camera OFF/ON (or when using
Auto Power Saving Auto Power Saving
). In these cases
the camera will initially return to the default setting for shutter speed
and aperture when automatic program mode is used again.
APERTURE PRIORITY - A
The camera electronics will calculate the correct shutter speed
automatically and steplessly. The calculation includes the set sensitivity,
metered brightness and the manually selected aperture.
▸ Press and hold the thumbwheel (≥ 1 s)
▸ Turn the thumbwheel
▸ Select
A A
▸ Set the aperture value
• The exposure time is then automatically derived from the prevailing
light.

Notes
• If the automatic sensitivity setting (
ISO Auto ISO Auto
) is activated at the same
time, the control range of aperture priority is extended. The shutter
speed will only be extended beyond the value derived from the
1/f 1/f
setting selected in the menu if the highest set sensitivity is reached.
• With very little light or extreme brightness it is possible that the
available shutter speed range is no longer sufficient for the preselected

Correct exposure metering will then be rendered impossible.
• In video mode, the slowest shutter speeds are dependent on the set
frame rate.
