I had a chance to ask directly to Pentax Japan and obtained the explanation but unfortunately lost it. As I remember it, it goes like this; 1. Pentax cameras are actually calibrated for either negative or positive film. I do not remember which one, but from what you and others are saying, it must be calibrated for slides. I thought it was the other way around though. I got exact EV range over the entire ISO range. Too bad I no longer have it. 2. When you load the film, camera reads whether it is a negative or positive film through the metal bar code on the film cartridge. I thought the bias is only for the negative film but not as much as 1EV. 3. Canon has the opposite setting/calibration. 4. I do not remember if this intentional calibration was for the entire line of Pentax SLRs or perhaps pz-1p had a opposite setting. I know this does not answer much to your concern (might only confuse you :-), but I know for the fact that there is an intentional bias built into the metering of Pentax camera. Cheers, Ken
