4. Automatic flash mode

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!
