That was my understanding as well. Also, yeah I realize that stopping down makes the meter less accurate due to light levels. Even so, f8 on a sunny day is not exactly dim. The pentax glass I have generally does ok, maybe at most requiring a stop EV compensation. Usually to the negative. As soon as you go wide open things start metering properly though. Its noticeable. It also makes zero sense since the camera is taking readings with the lens stopped down. It is possible that my aperture mechanisms on some of my lenses need cleaned and relubricated. Very likely in fact. So there might be some slop in accuracy. Even so, that wouldn't give consistent overexposure.
