High Speed Sync Flash With The Flash Unit's Ttl Hss Mode - Leica R9 Instructions Manual

High speed sync flash with the flash unit's
TTL HSS mode
For TTL controlled fill-in flash exposures (with
2
preset –1 / EV compensation) in conjunction
3
with selectively metered pre-flash/es.
Note:
If the shutter is released before firing a pre-flash,
depending on the manually or automatically set
shutter speed either no flash at all will be fired -
with speeds shorter than 1/250 s, or, with
speeds within the normal sync range, the camera
will trigger a TTL-controlled flash instead of a
high-speed sync flash.
The settings in detail:
1. Set exposure mode dial (1.11) to the m or A
position
2. Set the shutter speed dial (1.16) to the desired
value in m (1/350 s or faster); the setting is
ineffective in A
3. Set the aperture setting ring (1.12) to the de-
sired value (preferably large apertures, i.e. low
values; the highest available value in this
mode is 5.6)
4. Set the exposure metering method selector
(1.15) to the desired method
5. To power up the camera, lightly tap the shutter
release (1.17)
6. Set TTL HSS on the flash unit
Displays:
Unlike the normal flash mode, the minus sign
(2.5) appears in the viewfinder to the right of the
flash symbol, the shutter speed and
seen alternately (2.9 a/d) and the symbol for
selective metering (2.3 c) flashes to indicated
that a pre-flash has to be fired to determine the
flash exposure.
The flash unit display shows the maximum range
for this flash mode.
Note:
If higher values than 5.6 are set, the selected
exposure metering mode appears again instead
of the flashing selective point and
alternates with the shutter speed display to indi-
cate that pre-flash firing and therefore HSS
mode are not possible.
