4 When high-speed sync is used
with Type A cameras, the picture
is underexposed.
With high-speed sync, the Guide
Number changes depending on the
sync speed. A faster sync speed
reduces the flash range. If the sub­
ject is beyond the flash range,
underexposure results.
Set the shutter speed so that
the desired flash range is
obtained.

5 The subject looks blurred in the
picture
If the flash is used with the aperture-
priority AE mode in low light condi­
tions, a slow sync speed is set auto­
matically. A blurred picture may be
taken if the camera is handheld at a
slow shutter speed
Use of a tripod is recommended
at slow shutter speeds
