....With my *ist D and my Metz 40MZ-2/SCA3701, I can report the following behaviour with the FA 24-90mm lens: Put the lens at 24mm, the flash will report 24mm set on the lens itself: the flash reports 35mm, the camera 24mm
Same for the AF360FGZ:
the flash report the focal lenght corresponding to the covered FIELD; egal to the equivalent focal, not the real focal lenght.
