PZ-1 multi-pattern metering chart

[Joe Wilensky]

I recently picked up the original Pentax brochure for the PZ-1, and it has a chart in it that I haven't seen elsewhere.

It describes how the camera's multi-pattern metering essentially transforms itself based on the light level, the contrast level in the subject, and in some cases, the distance to the subject. In some cases, the eight segments essentially behave like a full-frame averaging meter, sometimes like a centerweighted meter, and only sometimes does the variable weighted metering come into play.

This was Pentax's first multi-segment metering camera (if you don't count the two-segment cell of the SF7/SF10. Is this pretty much how most multi-segment metering systems work?

See the chart and the paragraph preceding it at:

Since high-contrast subjects in bright light sometimes receive a different treatment based on the distance to the subject, would this change how multi-pattern metering works with A lenses, which don't transmit focus distance information?
