center and control contacts.
Synchronization Optionally triggered at the first or
second shutter curtain.

available.
Flash exposure metering (with SCA-3501/3502
a dapter or SCA-3000 standard flash unit, e.g.
LEICA SF 24D/LEICA SF 58). Control with center-
weighted TTL-pre-flash metering.
Flash measurement cell 2 silicon photo diodes with
collection lens in camera base.
Flash exposure compensation ± 3
steps adjustable on the SCA-3501/3502 adapter.

Displays in flash mode Readiness: flash symbol LED
in the viewfinder constantly lit; confirmation of suc -
cess: By the LED remaining lit or flashing rapidly for a
while after taking the picture; underexposure display
by the LED going out for a while.
Viewfinder
Viewfinder principle Large, bright-line frame view -
finder with automatic parallax compensation.
Eyepiece Adjusted to -0.5 dptr. Correction lenses
from –3 to +3 dpt. available.
Image field limitation By activating two bright-line
frames: For 35 and 135 mm, or for 28 and 90 mm, or
for 50 and 75 mm. Automatic activation when lens is
attached. Any pair of bright-line frames can be acti -
vated using the image field selector.
Parallax compensation The horizontal and vertical
difference between the viewfinder and the lens is
automatically compensated according to the relevant
distance setting, i.e. the viewfinder bright-line auto-

/ EV in / EV-

the lens.
Matching of viewfinder and actual picture The
size of the bright-line frame corresponds exactly to
1
/ EV
3
the sensor size of approx. 23.9 x 35.8 mm at a setting
distance of 1 meter. At infinity setting, depending on
the focal length, approx. 7.3 % (28 mm) to 18 %
(135 mm) more is recorded by the sensor than indi -
cated by the corresponding bright-line frame and
slightly less for shorter distance settings than 1 m.
Enlargement (for all lenses) 0.68 x.
Large basis range finder Split or superimposed
image range finder shown as a bright field in the cen-
ter of the viewfinder image.
Effective measurement basis 47.1 mm (mechanical
measurement basis 69.25 mm x viewfinder enlarge-
ment 0.68x).
Displays
Viewfinder (lower edge) LED symbol for flash status.
Four-digit seven-segment digital display with dots a -
bove and below, display brightness adjusted for ambi-
ent brightness, for: Warning of exposure compensa-
tion, display for automatically generated shutter
speeds in aperture priority mode, indication of use of
metering memory lock, warning that the metering or
setting ranges are overshot or undershot using aper-
ture priority and counting down exposures longer than
2 s.
LED light balance with two triangular and one central
circular LED for manual exposure setting. The triangu-
lar LEDs give the direction of rotation of the aperture
setting ring and shutter speed setting dial to adjust
the exposure. Also for warning of when the metering
range is overshot or undershot.
On rear panel 2,5" monitor (color TFT LCD) with
230.000 pixels, for displays see p. 98.
