High speed sync flash with the flash unit’s
TTL HSS
mode
For TTL controlled fill-in flash exposures (with
preset –1
2
/
3
EV compensation) in conjunction
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 1/250s, 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 (1/350s 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 can be
seen alternately (2.9a/d) and the symbol for
selective metering (2.3c) 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 no longer
alternates with the shutter speed display to indi-
cate that pre-flash firing and therefore
HSS
mode are not possible.
