This is basically just a problem with the latitude of the film. Slide film cannot record high contreast scenes. For slide film you should usually expose for the highlights but the camera doesn't know that and tries to average the scene (like all meters - including center weighted). In some circumstances you have to overide any meter. > > There was a post here sometime ago from an owner of the MZ-S who said > that it does not seem to overexpose.

Pentax have one of the best matrix metering systems in the industry; just look at what Andy Rouse says about his switch from the Canon EOS-1v to Pentax - no need to constantly override the matrix meter anymore. He fully rely on Pentax AF and matrix metering. The matrix metering of my 645n and MZ-S (and for that matter the Z-1p) is several magnitudes more "right" than center weighted metering. No meter is correct all the time but it is really boring to almost always figuring out that the matrix meter is right 95% or more of the time with Velvia. I always (when time allows) check the matrix reading with a spotmetering. Practically always, the matrix meter is within 1/3 of a stop; a difference that qualifies as "taste" in exposure.
