Some of this is not rightly described. I used plenty of M and K lenses on my PZ-1 from the first day I bought it new. The camera manual poorly describes the special functions. It was not until I read this list that I actually understood them with regard to spot, center weighted, and matrix metering. Let me try to remember what I know...
Spot metering: Not available with any M or K lenses! Try it with an M lens then with an A lens. Only A or newer lenses will work on spot metering. Matrix vs Center Weighted: My memory is fuzzier here. I don't think M & K lenses can do anything but Center Weighted. Again, you need A or better lenses to Matrix meter. Confusing PF Functions: You can set the PF function to do Spot or Center Weighted metering when you press the Spot button on the back... BUT this only works if you are using an A or newer lens. With the K & M lenses, you get Center Weighted metering no matter what!!! Press the button or not! This was not clear to me for a long time from reading the camera instruction manual. On the PZ-1, when you use an A, F, or FA lens, you get matrix metering. With the PF function, you set the camera to do Matrix & Spot, or Matrix & Center Weighted at the flip of that Spot button...provided you use an A, F, or FA lens. This option can cause some variation in how your slides are exposed. I came from a Super Program and knew precisely how Center Weighted metering would render Kodachrome 64 and what adjustments to make. When I started putting A or FA lenses on the PZ-1, I got some suprises on exposures. To this day, I prefer Center Weighted over Matrix metering on the PZ-1. Regards, Bob S.
