OK, here we go - I'll try my best. From H�necke' MZ-5n/MZ-3 book (page  
42):

"... Beside the different valuation of the upper and lower regions of a  
motiv, the multisegment metering considers the shadows in a motive more  
than the lighter regions. This reaction on shadows reaches its maximum  
in case of back-lighting, where only the center will be measured. The  
multisegment metering includes the object distance, measured by the AF- 
system of the MZ-5n/MZ-3, in this compensation of the darker motiv in  
the center and the lighter background. ..."

And Horst Gottfried writes in his MZ-5n/MZ-3 "Fotoguide" (page 37):

"... If the multisegment metering recognizes a dark area in the center  
of the picture, then this is a verl reliable sign of a back-lighting  
situation. In this cas the metering system considers the distance  
information of the AF-system in order to get a compensation as optimal  
as possible. The nearer the the main motiv the stronger its evaluation  
in the exposure analysis...."



So may we call it 3D metering? ;-) I would say 'yes'. But it seems as if  
the distance information is not taken into account in every case but  
especially in back-lighting situations. Does anyone know more detailed  
technical sources for such information?

Cheers, Heiko
