Metz Canon Eos SCA 3102 M5 - Manual (Page 19)

If a decentral AF sensor is manually selected by the
photographer or autonomously by the camera, then
the AF measuring beam of the mecablitz will not be
activated. In this instance some cameras select the
AF illuminator integrated in the camera (please
refer to the operating instructions for the given
camera).
The following EOS camera models only activate the
camera-integrated AF illuminator: EOS 500, 5, 10,
10S, 5000, REBEL X, REBEL XS, A2, A2E, 888, G.. .
6. Maximum flash range indication
Only possible with the mecablitz 44 MZ-2, 50 MZ-
5, 54 MZ-... , 70 MZ-... and 76 MZ-5 (flash units
with LC-display).
The camera transmits to the flash unit the data
relating to the speed of the loaded film (ISO), the
aperture, the focal length of the lens and the
adjusted exposure correction. The flash unit
computes the corresponding maximum flash range
on the basis of the camera data and its own guide
number. The selected aperture and the
corresponding working range (minimum and
maximum flash-to-subject distance) are indicated
on the flash unit's LC-display.
Note:
The maximum flash range is not indicated on the
flash unit's LC-display when the reflector is
swivelled or tilted.
