Please bear in mind that the maximum ash range changes in accordance with the focal length in use. At ISO
100 you can read o the values for the ash range from the table below:
Mounting and Removing the Flash from Camera
Before mounting the ash unit onto your camera, be certain that the power switch
is turned OFF. The camera´s built-in ash must be shut and locking ring must be
turned.
Models Nikon, Canon, Pentax/Samsung and Panasonic:
Carefully slide the ash unit onto thecamera´s ash shoe. In order to guarantee a
proper functioning contact between ash and camera, the locking ring should be
tighten. When removing the ash from the camera, reverse the steps.
Model Olympus:
Carefully slide the ash unit onto the camera´s ash shoe. In order to guarantee a proper functionating
contact between ash and camera, the LOCK button should be pressed. When removing the ash from the
camera press the two buttons along side LOCK. Now you can easily remove the ash unit from the camera.
Model Sony/Minolta:
Slide the ash unit onto the camera´s ash shoe until it locks into place. In order to remove the ash unit from
the camera, press the PUSH button. Now the ash can easily be removed from the camera.
Color Temperature and White Balance
Color Temperature of the DAF-42 is 5000 K. The automatic white balance of digital cameras automatically
selects this color temperature. Color dierences can occur with changing light. It is therefore recommended
to set the white balance manually on your digital camera. Depending upon the camera model the white
balance would be set at 5000 K or ash symbol.
TTL Flash Control with Auto Mode
After connecting the ash onto your camera, rst turn on your camera and set it to auto mode and then turn
the power switch of your ash to ON. The ash is preset to TTL ash control. On the LC display appears
“TTL”. When the ash READY indicator lights up on the ash, you only need to press down the shutter
release of your camera. Most cameras also feature a ash ready indicator in the viewnder. (Please refer to
your camera´s instruction manual.) TTL ash control ensures exact illumination of the object by controlling
both the camera´s and the ashgun´s amount of light. The ashlight reecting o the object is measured
through the lens (TTL - through the lens). When the amount of light needed for an accurate exposure has
been reached, a stop signal is passed to the ash causing the light output to be interrupted. Additionally
your camera automatically is preset to the best possible aperture and exposure time. TTL ash control oers
besides high exposure accuracy and easy handling further advantages:
• all settings and exposure adjustments are omitted
• extensions are automatically considered (e. g. when using extension tubes)
