Metz 34 AF-3 P operating instructions Autofocus measuring flash

7. Autofocus measuring flash

Notes:

•The AF measuring flash is only supported in the camera's "SINGLE AF" mode.

•When the camera’s autofocus system is on, the electronic circuit will automatically activate the autofocus measuring flash whenever the prevailing light is insufficient for the exposure.

•The range of the autofocus measuring flash depends on the speed of the lens (maximum aperture)! With an f/1.8 standard lens of 50 mm focal length, the range is approx. 6-10 m (depen- ding on the sensitivity of the camera’s AF sensor).

•Due to parallax between camera lens and AF measuring flash, a minimum distance of 1 m to the subject is necessary. The AF measuring flash will not cover the subject if the shooting distance is less than 1 m. In such instances ensure a higher ambient light level.

Low-speed lenses, e.g. with an aperture of f/5.6 or f/8 (such as zoom lenses), significant- ly restrict the range of the autofocus measuring flash!

•The AF measuring flash is not activated in the camera's continuous focusing mode or when the autofocus system is switched off.
