Thank you Godfrey, et. al... Godfrey: when you say that good modern cameras allow for both CW and multi-segment, do you mean this in terms of a setting (a switch) made on the camera body? I ask because my ZX-M goes into CW mode when using an older lens (i.e. an M-series lens). Is this what you had meant, or were you referring to a body setting? I have not noted a body setting on my ZX-M for CW metering. I just love the ZX-M-- especially with the added weight of the battery pack--and I would not want to have to part with it (in fact, I am thinking of getting another ZX-M body)...unless it were inhibiting my skill development in some way. Advice is welcome.
