QFLASH T5D-R & X5D-R
PHOTO - VIDEO - PRO AUDIO
Studio Quality, High Power Automatic/TTL Portable Flashes
The T5d-R and X5d-R are the latest evolution of Quantum's
proven portable Qflash units. Used with FreeXwire, they
support wireless control of all dedicated camera-flash
functions – including Manual, TTL, Auto, Auto-fill and
TTL-Ratio – up to 500 feet away. They blend seamlessly with
Canon, Nikon and other professional digital camera systems,
using proprietary QTTL adapters. In some cases, they even
provides capabilities a camera system may not support–such
as wireless remote Fill-Flash!
The Qflash T5d-R is powered by a Turbo or Turbo 2x2 to
produce powerful GN 160 auto-flash power, while the Qflash
X5d-R is powered by Quantum’s Qpaq-X, as well as
Lumedyne or Norman power packs. At 400 watt-seconds
X5d-R produces GN 220 flash power. Both flashes 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 locking function. Flash control is either automatic, TTL (with optional adapters), manual, or stroboscopic.
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 par-
abolic reflector. Coverage includes 55° (nor-
mal 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 ex-
posure 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 dis-
play. 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 T5d-R / X5d-R lim-
its 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 is great automatic
exposures in all situations.
