5.10.8 Quick Turn off

If you are using the Qflash as an on-camera flash and want to disable the

flash for a few shots you can use the ‘quick turn off’ feature.

To activate the quick turn off feature press Mode I twice. The word ‘OFF’

will appear in the display. To return to normal operation press any button

(except Test M).

Note: This feature will only prevent the flash from firing; it will not turn off

the Qflash or the Turbo. To completely turn off the Qflash the Turbo must

be turned off.

5.10.9 Modeling Lamp

The Lamp button activates the modeling lamp. The lamp lights for sev-

eral seconds and shuts off.

Quantum’s QTTL

adapters provide a dedicated link between Qflash 4d

and popular digital and film cameras. QTTL D series adapters can support

the following camera functions, when supported by the camera:

IMPORTANT! With digital cameras perform a custom white balance

prior to a shooting session. Otherwise, the camera will assume you

are using some unknown flash.

6.1 Controls, Displays, and modes

Please refer to sections 5.1, 5.2, and 5.3 to operate the Mode I, Set G

and Up/Down JLbuttons.

Note that with D series adapters the film speed (ISO) and F# are con-

trolled by the camera. To change the F# or ISO adjust your camera.

With some cameras, press the shutter half way periodically to update

the F# and ISO information on the Qflash display.

6.2 Qflash in Manual mode

If Qflash is set to Manual mode using a QTTL adapter flash exposure is

fixed by the settings on Qflash. In Manual mode the following QTTL fea-

tures are available: Rear curtain sync (Section 6.5.1), Auto focus assist

(Section 6.5.2), Shutter speed control (Section 6.5.3), Ready light (Section

6.5.4).
