A typical situation where MZ-5N multisegment fails is a common
horizontal mountain landscape with the lower half of the image
occupied by the dark-gray ridge, while the above is a blue sky with
white clouds. Light is flat (with side or back light things get
worse).
On slide film (Sensia, RSX, CTPrecisa, Elitechrome, you name it) sky
gets burnt out with clouds barely distinguishable while mountain is
rendered almost correct. But close the aperture one stop and voila,
sky is acceptable and there still are enough details on the
mountain.
On negative film, the original multisegment exposure gives enough
details both on sky and mountain for the processor to render
correctly everything.

I strongly suspect that cameras above MZ-5N are all capable to read
the DX-coded film latitude and use it to adjust exposure
specifically for the film loaded (obviously, this is not the case
with 645n which may be simply biased for slide film).
