Flash operation using standard SCA 3000/3002
flash units and SCA 3501/3502M3 adapters
When a suitable flash unit is connected via an
SCA 3501/3502M3 adapter, the LEICA R9 offers
decisive advantages in many situations and helps
you to achieve successful flash photographs.
Depending on the selected mode, the camera
performs various functions automatically, while
still leaving you the necessary creative freedom
to compose flash photographs according to your
requirements.
• Flash exposure metering during exposure and
through the lens (TTL metering). This TTL flash
exposure metering is recommended for macro
photography, when using a filter or with zoom
or telephoto lenses.
• All information about the flash charge status
and flash over- or underexposure is displayed
in the viewfinder and in the rear panel display.
• Automatic switching to flash sync speed
(depending on the mode).
• Flash exposure compensation, i.e. selective
over- and under-apportionment of the light
from the flash to illuminate shadows in the
foreground regardless of the available light or
to obtain a better distribution of the light in
backlighting situations (only on adapter or
flash unit, see p. 162).
• Transmission of the lens focal length for auto-
matic reflector adaptation of the flash unit
(only for lenses with electrical contacts).
• Transmission of the set lens aperture for con-
trolling the flash unit’s automatic computer
mode (only for lenses with electrical contacts).
• Display of intermediate aperture values when
using zoom lenses of differing apertures (only
for lenses with electrical contacts).
• Transmission of the film speed and camera
exposure compensation settings for control of
the flash unit.
• Automatic switching to slower shutter speeds
when using strobe flash.
• Automatic flash exposure series (only with
appropriately equipped flash units).
