what do you mean by "match perfectly"? 
focussing alike? stereo-Mikroma's fixed focus lenses were fatory-set 
to focus at different distances. at least one american camera 
(Graflex?)shared this feature.

Indeed I'm afraid active-autofocus cameras can cross-read reference 
beams, yealding to TOO gross focus mismatch. 
But this is a fear of my own, and I will be glad to know if somebody 
experienced such an inconvenience.

P.S. I prefer manual settings, so I usually use stereo cameras. 
but sometimes one needs a broader stereo-base, and full manual 
settings would hobble the use of paired cameras to non-action 
pics.
