• Some cameras support the AF measuring beam in the
flash unit only with the camera’s central AF sensor.
If a peripheral AF sensor is selected, then the AF
measuring beam will not be activated in the flash unit.
Activate the central AF sensor.
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 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. 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 manually a positive flash
exposure correction at the camera, e.g. +1 EV.
The shots are too bright.
• Certain minimum lighting distances must be
maintained for close-up shots to avoid over-exposure.
The minimum distance from the subject should be at
least 10% of the maximum range.
