This is not normal. The MZ-S has a very precise multipattern meter. If anything, it slightly underexposes. However, Pentax matrix metering may run into problems with certain lenses. It works best with Pentax FA lenses since these transfer information about possible vignetting of the lens to the camera and this info is used in exposure measurement. I had problems with my Z-1p and two A-series lenses; the A 24/2.8 and the A 35/2.8. The 24mm gave about 2/3 stops overexposuire when in matrix mode whereas the 35mm would yield 0.5 stop overexposure. All other A lenses worked fine but they where telephotos. I figured out that light fall-off at the corners of the wide-angle lenses affected the matrix metering. This may also occur with zoom lenses where the effect could vary with focal length. Are you using non FA lenses? P�l - This message is from the Pentax-Discuss Mail List.
