• You can press the +/-
button to change the flash
compensation (adjust the
flash power level) on the
screen for setting the flash
compensation.

flash mode of the camera,
you need to select the

• Before photographing with
the flash unit using the
self-timer of the camera,
make sure that the TEST
button is lit.
• If flash compensation is
made both on the flash
unit and the camera, both
compensation values are
added up for flash firing.

Auto WB adjustment
with color temperature
information
White balance is automatically
adjusted on the camera (except
for DSLR-A100) based on the
color temperature information at
the time of flash firing.
• This function works when the
flash unit is attached to the
camera and placed in TTL flash
mode.
• This function works when
[Auto] or [Flash] is specified
for the white balance on the
camera.
TTL*-flash mode
Manual-flash mode
provides a fixed flash power
irrespective of the brightness
of the subject and the camera
setting. TTL-flash mode
measures the light from
the subject that is reflected
through the lens.
TTL metering also has a
P-TTL metering function,
which adds a pre-flash to
TTL metering, and an ADI
metering function, which
adds distance data to the
P-TTL metering.
* TTL stands for Through The
Lens.
• ADI metering is possible in
combination with a lens with
a built-in distance encoder.
Before using the ADI metering
function, check whether your
lens has a built-in distance
encoder by referring to the
specifications in the operating
instructions supplied with your
lens.
