Exposure Modes; Programmed Automatic Exposure Mode; Program Shift; Aperture Priority - Leica S2 Instructions Manual

Exposure modes

The LEICA S2 provides you with a choice of four exposure
modes.
Programmed automatic exposure
Setting the mode
1. Set the shutter speed dial (1.10) to A.
2. Press the click wheel (1.18) to set automatic exposure con-
trol, i.e. in this case automatic program mode.
The shutter speed and aperture are then generated automatic -
ally according to the available light and continuously between
1 1
32 s and / s, or / s when using the central shutter in
4000 500
some Leica S lenses and between fully open and minimum
aperture for the relevant lens.
Viewfinder and top panel display show
• P (2.5.a/3.8) for the selected exposure mode, and
• the automatically controlled aperture (2.6/3.11) and shutter
speed values (2.8a/3.12).
Notes:
• If the automatic sensitivity setting (see p. 30) is activated at
the same time, even with a fully open aperture the shutter
1
speed will only be extended over /
Focal length
set sensitivity is reached.
• With very little light or extreme brightness, the available
speed/aperture range may no longer be sufficient. In this
case, (2.8b) appears in the viewfinder for underexposure
(possibly accompanied by a warning that the metering range
has not been reached, see "Working below the metering
range", p. 36), or (2.8) appears for overexposure.
38 /Automatic program / Program shift / Aperture priority

Program shift

The program shift function on the LEICA S2 enables you to
change the shutter speed/aperture combination set by the
automatic program, while the overall exposure, i.e. the brightn-
ess of the image, remains unchanged.

UPDATE
Turn the click wheel (1.18)
- to the right for larger apertures (lower values) or faster shutter
speeds
- to the left for smaller apertures (higher values) or slower shut-
ter speeds.
Viewfinder and top panel display show
• P (2.5.a/3.8) for the selected exposure mode,
• S (3.10) in the top panel display to indicate the use of the shift
function, and the automatically controlled aperture (2.6/3.11)
and shutter speed values (2.8a/3.12), which change inversely.
Note:
Shift settings are retained
- after taking a picture beyond the exposure metering system's
12 s retention time (see p. 32),
- but not when you switch to a different exposure mode (A, T, m)
if the maximum
- when you turn the camera off and back on (including Auto
Power Off).
This means that in these cases when you use the automatic
program mode again the camera initially always specifies the
default shutter speed and aperture setting.
Aperture priority - A
Setting the mode
1. Set the shutter speed dial (1.10) to A.
2. Press the click wheel (1.18) to set manual aperture control.
3. Turn the click wheel (1.18) to set the required aperture.
The shutter speed is then generated automatically based on the
available light and continuously between 32 s and
1
/ s when using the central shutter in some Leica S lenses.

Viewfinder and top panel display show
• A (aperture priority) for the selected exposure mode
(2.5.b/3.8),
• the manually set aperture value (2.6/3.11), and
• the automatically set shutter speed (2.8a/3.12)
Notes:
• If automatic sensitivity setting is activated at the same time
(see p. 30), the control range for aperture priority is extended.
• With extreme brightness or in conditions of very poor light,
or appears in the viewfinder (2.8b). Set a different aperture
value if possible. may also appear to warn you that you are
below the metering range (see p. 36). It is then no longer pos-
sible to correctly meter the exposure.
