Studio Quality, High Power Automatic/TTL Portable
Flashes
The Qflash T4D is powered by a Quantum Turbo or
Turbo 2x2 to produce powerful Guide Number 160
auto-flash power, while the Qflash X4D is powered by
Quantum’s Qpaq-X, as well as Lumedyne or Norman
power packs. At 400 watt-seconds Qflash X4D
produces GN 220 flash power. Both Qflashes have a
stroboscopic modeling light, and both use parabolic
reflectors for softer, cleaner light. The reflectors are
removable for bare-bulb lighting. The flash head
bounces and swivels and can be locked into place with
the new locking function. Flash control is either
automatic, TTL (with optional adapters), manual, or
stroboscopic, to be precisely what you need. Qflashes
can be ganged together to produce flexible lighting
setups with thousands of watt-seconds of auto or
manual flash power. Qflashes mounts on a camera bracket, tripod, or lightstand and weigh no more than a conventional flash.
◆ Automatic exposure control covers a nine
stop range, adjustable every 1/3 stop, for a
total of 25 automatic settings.
◆ Manual power can be adjusted from full to
1/64 power in 1/3 stop increments. Flash
power can be precisely what you need.
◆ Store up to eight of your favorite settings
(for example, auto @ f/8, f/16 manual @ 1/4
power) and switch between them at a push
of a button.
◆ To avoid harshness that can be produced by
rectangular reflectors, the Qflashes use a
parabolic reflector. Coverage includes 55°
(normal position), 70° (wide angle) and 90°
(with supplied diffuser). Or remove the
reflector for 360° bare-bulb coverage.
◆ With optional adapters for TTL cameras,
you can control the Qflash exposure
through-the-lens. TTL operation indicates
visually as well as audibly the proper and
under/over exposure.
◆ QTTL adapters link the most popular digital
and film cameras to Qflash Digital. Allows
you to select rear curtain sync and/or auto
focus assist light.
◆ Stroboscopic mode can be adjusted for flash
power, and number and frequency of bursts.
Select a strobe rate of 1 to 50 flashes per
second. You can also select the power level
and the total number of flashes from 1 to 20.
◆ LCD shows minimum and maximum flash
distance range for each auto setting, mode,
F#, GN #, flash ready, OK and under/over
exposure checks. Readouts can be converted
between feet or meters. Also provides
audible indication of correct exposure.
◆ Automatic Fill Mode allows setting fill flash
ratios (-3 to +2 stops in 1/3 increments)
when used with one of the QTTL adapters.
Fill-flash ratios can be controlled even for
cameras that don’t have fill-flash capabilities
◆ One Qflash can control the exposure of an
unlimited number of Qflash “slaves”
connected to it for increased lighting power,
or lighting difficult subjects with multiple
flash heads. Slaves are controlled via a TTL
adapter or their own auto setting. Each can
be set independently–to its own automatic,
manual or stroboscopic exposure for precise
lighting ratios and light control.
◆ If you are using Qflash on-camera and you
want to disable it for a few shots you can use
the “quick turn off” feature. Press the
MODE button twice and “OFF” appears in
the display. Press any button (except the test
flash) to return to normal operation.
◆ Optional remote sensor lets you put Qflash
anywhere you want (up to 100´ away with
cable extensions) and read the light at the
camera position.
Automatic Sensor Limit
This option on the Qflash T4D / X4D limits
the distance the Qflash sensor “sees” when in
Auto mode. Without Auto Sensor Limit, if the
subject has no background (in a open field
outside), or the background is far away (a large
catering hall), the flash sensor tries to balance
the subject and background light. The subject
is bright, and the background is dark, and the
result is an over exposed subject. By limiting
sensor distance, the sensor will no longer try
to balance the light from a far background and
will focus only on the subjects that are within
the sensor limit. The result, great automatic
exposures in all situations.
