TTL
The TTL fill-in flash BL cannot be set.
• There has been no exchange of data between the flash unit and the camera.
Tap the camera's shutter release.
• The camera does not support TTL fill-in flash mode.
• The camera is switched to spot metering. Choose another metering type, for
example multi-zone metering.
The setting for manual TTL flash exposure correction has no effect.
• The camera does not support manual TTL flash exposure correction on the
flash unit (Group A cameras, for example).
Automatic switching to the flash sync speed fails to occur.
• The camera has a between-the-lens shutter (as do most compact cameras),
Switching to sync speed is therefore unnecessary.
• The camera operates with FP high-speed synchronisation (camera setting). In
this case no switching to sync speed occurs.
• The camera operates with shutter speeds that are slower than the flash sync
speed. Depending on the camera mode, there is no switch to flash sync speed
(see the camera's operating instructions).
The shots have shadows in the bottom of the image.
• Because of parallax error between lens and flash unit, close-up shots may not,
depending on the focal length at the bottom of the image, be fully illuminated.
Tilt the main reflector downwards or turn the wide-angle diffuser in front of
the reflector.
The shots are too dark.
• The subject is beyond the range of the flash unit. Note: Using bounce flash
reduces the range of the flash unit.
• The subject contains very bright or highly reflective areas. The metering
system of the camera or flash unit is deceived as a result.
Set a positive manual flash exposure correction, e.g., +1 EV.
The shots are too bright.
• In close-up shots, overexposure (shots that are too bright) may result if the
shutter speed is faster than the flash sync speed. The minimum distance from
the subject should be at least 10% of the maximum flash range indicated on
the display.
The aperture (f-stop) cannot be adjusted on the flash unit.
• There is an exchange of digital data between the flash unit and camera.
Adjustment of the aperture is not possible!
