Note: The descriptions of each of the modes indicate whether
they can only be selected using the “2nd setting level” (applies to
No. 3–5 and 8–14).
Important: Once selected, a mode remains active until you select
another one. If, on the other hand, the camera is switched off or
switches itself off, the default setting is active when it is switched
on again. However, if a mode has been stored it becomes the
default mode and remains active even when the camera is turned
on and off (see “Storing flash modes/the set exposure compen-
sation” on p. 108).
Photography with and without flash
The LEICA CM has a built-in flash (5), which either fires automat-
ically or can be manually switched on or off, depending on the
selected mode.
It is also possible to use a pre-flash light (3), in order to reduce
the “red eye effect”.
The ISO flash shoe (11) also allows the use of more powerful ex-
ternal flash units, preferably models that meet the SCA-3002
standard (with SCA-3502 M4 adapter), which in many cases can
completely prevent “red eye effect” due to the larger distance of
their flash reflectors from the lens axis. We specifically recom-
mend the LEICA SF 24D (order No. 14444/14448)
Instructions for using external flash units
• As soon as a system-compatible external flash unit is at-
tached, the set flash modes with pre-flash function (No. 2, 4,
7, 9, and 12) are reset to the otherwise identical modes with-
out pre-flash (No. 1, 3, 6, 8, and 11) and displayed accordingly
in the data panel (19).
However, when the flash unit is removed the camera is reset to
the stored mode, i.e. either to
a
(the default factory setting,
see p. 89) or the mode you have permanently stored (see
“Sto
ring flash modes/the set exposure compensation”, p. 108).
• On the LEICA SF 24D, the mode TTL/GNC should be set to al-
low automatic control by the camera. When set to A, subjects
with above or below average brightness may not be optimally
exposed. When set to M, the flash exposure must be adjusted
to the aperture and distance values set by the camera by set-
ting a corresponding reduced power output level.
• For SCA-3002 standard flash units:
1.
To retain the automatic flash exposure control, an SCA-3502
M4 adapter is required.
2.
It must be possible to set the flash unit to a mode that
allows the camera’s guide number calculation to control the
flash power (Guide Number Control, see the relevant flash
instructions).
• For all other SCA system flash units and earlier adapters than
the SCA-3502 M4:
1. The flash unit must be set to A or M.
2. For M, the reduced power output must be determined by
guide number calculation and set manually on the flash
unit.
• For non-SCA flash units:
1. The only available flash modes are manual flash activation
and deactivation (No. 6 and 15).
2. Only aperture priority can be used on the camera (when
setting to programmed automatic exposure mode,
appears in the viewfinder and the shutter release button is
blocked).
