3. Automatic flash mode

In the auto flash mode, the flash unit’s sensor

￿measures the light reflected from the subject. The flash is cut off as soon as sufficient light has been emitted for correct exposure.

This eliminates the need to recalculate and readjust the aperture each time the shooting distance is changed, pro- vided that the subject remains within the indicated auto flash range.

Setting procedure for automatic mode (fig. 4):

Example: Flash-to-subject distance 5 m Film speed ISO 100/21°

Focal length, e.g. 50mm (35mm format)

The mecablitz is used without a W or T attach- ment in place.

Taking into account the maximum effective range , a flash-to-subject distance of 5m (see table at the back of the unit) permits the use of the auto-working apertures f/4 or f/2 . The maximum range with an auto-working aper- ture of f/4 is 7 m, and with f/2 up to 14 m. The minimum lighting distance is approx. 10% of the maximum effective range.

☞The subject should be in the middle third of the distance range. This gives the electronics suffi- cient leeway for compensation should this pro- ve to be necessary.

• Set the operating mode selector	to the required auto-
working aperture.

For the shortest-possible depth-of-field (as is required in portraiture) the use of an auto-working aperture of f/2 is recommended. For group shots with a number of people standing behind each other, set an auto-working aperture of f/4 to extend the depth-of-field.

• Turn on the flash unit with the main switch .

• Switch the SLAVE function selector to position 0!.

•Set the camera to flash synch speed or a slower speed.

•Await flash readiness which is indicated by the green

flash-ready light .

☞Caution with zoom lenses!

Due to their design they can cause a loss of light in the order of up to one f-stop. Further- more, the effective aperture can also vary, depending upon the adjusted focal length. This can be compensated by correcting the apertu- re on the flashgun manually!
