4. FEATURES AVAILABLE WITH QTTL
(D, Dw, Dw-R SERIES) ADAPTERS
Quantum's QTTL ® adapters provide a dedicated link between Qflash 5d-R
series and popular digital and film cameras.
Wireless multiple ratio TTL - with Dw-R series Adapters & FreeXWires,
remote Qflashes can be set to ratios of the camera's TTL metering
system. For example, an on-camera flash could be set 1.6 stops down, a
main flash on the left to +1 stop, and a hairlight to –2 stops from the
camera TTL exposure.
Wireless preflash TTL with digital cameras - when using Dw or Dw-R
series QTTL Adapters, you can control Qflash exposure wirelessly with
your camera's TTL exposure control system.
Rear curtain sync - If supported by your camera, the QTTL adapter can
fire Qflash in sync with the rear curtain. Rear curtain sync is selected by
a switch located on the back of the adapter.
Auto focus assist - If your camera requires an infrared focus assist, the
QTTL adapter will project a beam when the camera focuses.
Flash Sync speed control - If flash readiness is achieved, the camera's
automatic system switches the shutter speed to the correct flash sync
speed.
Ready light - Flash readiness is established when the "Ready" indicator
appears in the Qflash display. If "flash ready" is supported by the camera,
then a flash symbol will appear in the viewfinder when Qflash is recycled
and ready.
Pre-flash TTL - Cameras that have advanced TTL metering systems
require a pre-flash to determine proper exposure. This pre-flash is sup-
ported by the QTTL adapters.
QTTL adapters support the features mentioned above only when the
camera connected also supports those features. Please see the list of
adapters available for cameras in the latest Quantum Price List or at
www.qtm.com.
