David, So you can use Matrix metering with M lenses? My manual says "For lenses made earlier than Pentax-M (lenses without lens information contacts), center weighted metering system is used instead of multi(8)-pattern metering. However the spot metering system can be used." This is non-sense since K and M lenses have identical mounts...no electrical contacts.
My PZ-1 definitely doesn't do this. You are not the first person to claim that their PZ-1 worked with Spot metering for K & M lenses. But you are first to tell me that after an actual test of their PZ-1 with a stock M or K lens, they got different aperture readings... that they had the spor meter functionality. Perhaps there are some PZ-1 cameras that work like this. I look at the discrepancy as a translation error in the camera manual. And as I said before, the Japanese are the ones who told me about the missing functionality. Regards, Bob S.
