i-TTL-BL flash mode
With this setting in i-TTL flash mode, the camera
additionally takes into account data relating to the
subject’s distance (see above). In this mode, the
reflector status (operation with or without wide-
angle diffuser or telephoto attachment) must be
adjusted correctly. For more details see Section 3.
For i-TTL-BL flash mode, both the camera and the
lens must support the evaluation of distances (see
operating instructions of the camera and the speci-
fications for the given lens).
Some cameras only support the i-TTL flash mode
for SPOT exposure metering. The i-TTL-BL flash
mode can then not be activated.
Settings and displays
• Switch on the flash unit.
• Continue depressing the “MODE” button until
“i TTL” and the symbol flash on the display.
Appropriate cameras will then automatically
activate the i-TTL-BL flash mode.
• The setting becomes immediately effective and is
automatically saved after 5 sec.
4.5 Only 28 AF-3 O digital:
TTL with preflash for
Camedia digital cameras
The TTL flash mode with preflash metering is an
advanced variant of the “normal” TTL flash mode.
Prior to shooting, the reflection of the subject is
measured with a preflash. The camera evaluates
the reflected preflash light so that the subsequent
flash exposure is optimally adapted to the pre-
vailing photographic situation (see operating
instructions of your camera).
Settings and displays
The flash unit must be switched to “TTL” mode
(see 4.1). This is not specifically displayed by the
flash unit.
The camera system does not permit “normal”
TTL flash control without metering preflash.
