One thing I learnd from a erlier F280 discussion is, that the
puls frequency is not constant. The flash raises the flash rate
during the exposure.
When I first heared of this It made me insecure too. But
I guess this is to compensate for the capacitor voltage drop,
(less energy per flash) to keep the light output lever equal.
I think Olympus did a lot of engineering effort, to make the
flash characteristic as simple as possible. So it acts just like
another continious light source. Not more not less.
Only the output level is a bit low. Still looking for a suitable
flash Zoom adapter.
