The permissible distance range and the corresponding aperture appear on the
LC display.
The subject should be located within the middle third of this distance
range, thus giving the electronic control sufficient scope for compen-
sation, if necessary.
There is a certain measure of overlap between the individual working apertures.
As a result of this overlap it is always possible to place the subject within the
middle third of the range.
Caution with zoom lenses!
Due to their design they can cause a loss of light in the order of up to
one f-stop. Furthermore, the effective aperture can also vary, depen-
ding upon the adjusted focal length.This can be compensated by
correcting the aperture on the flashgun manually!
