MZ-S could have more light/shadow patterns stored in metering system memory. In Z-20 there were stored "thousends" of these situations (according to H�necke - "Z-20 Laterna Magica"). I suspect, that with every new model there could be stored more and more patterns, that will cover more difficult lightning situations. I have shot few rolls of unforgivable Velvia 50, and must say that percent of badly exposed frames was about 10 - here it was my mistake - I should use spot metering/bracketing + own metering system (my brain :-) My former body - Z1P has had tendency to slightly overexpose slides - MZ-S does it exactly (almost) as I want...

Both systems use pattern similar to sensitivity zones of human's eye (unlike Canon and Minolta - they both use regular pattern dividing picture in 14-35 the same size and shape zones). Nikon works essentially the same way as Pentax meter - it uses database of many thousends light/shadow situations and compares it to current readout. Then it sets accordingly shutter or aperture. "3D matrix metering" is promoted as the one using distance info to provide more precise results. But since all Pentax AF lenses (both older SMC-F and new SMC-FA) provide distance information for bodies, Pentax meterig could use this information too, but as usual you can not find any information in Pentax marketing materials (as usual). In fact I haven't even find info how exactly Pentax matrix metering works, until I have H�necke book (anyway great book, it's a pity it is not available in English, and the last on of this serie was written for MZ-5 as I rmember...) -- Best Regards Sylwek
