But for the Panasonic DMC-FZ1000 it is not suitable.
Reason:
Because of the super zoom lens, the internal flash will not only high, but also forward.
The unfolded flash is facing further than the two lateral black holder are long.
So he's too close to the Streuchscheibe and the desired effect (soft shadows) fizzles or is barely visible.
The only meaningful purpose is that (when the lens is completely lowered down on the lens) of the shadow from the internal flash with wide angle shots can hardly be seen yet.
In addition, it can not be pushed fully into the hot shoe.
He goes into a maximum of 2/3, whereby the flash is a little closer to the lens.
To an external Bliz you therefore can not avoid in the FZ1000.
