Metz MECABLITZ 20 C-2 - Manual (Page 70)

The camera-to-subject distance is approx. 5 m.
You choose the f/2,8 “green” auto-working
aperture (maximum flash range given by the
aperture calculator: approx. 7 m)
Set the aperture selector of the flash to the des-
ired auto working aperture , i.e. “green”.
Set f/2,8 on the camera lens.
Caution with zoom lenses! Depending on
their design they can cause a loss of light
of as much as one aperture increment.
They may also have different effective
aperture values for the different focal
length settings. This will then have to be
compensated by manual correction of the
aperture setting on the flash unit!
6.2 Manual flash mode „M“
The flash always fires uncontrolled flashes at
full light output when in manual mode.
Adaptation to the given photographic situation
is achieved by selecting a corresponding aper-
ture on the camera.
• Set the main switch of the flash at the “M”
position.
