I noticed the matrix metering problem with F100 and b&w films several years ago. I tried to raise the issue but people wouldn't notice or told me to fiddle with ISO values. This is nonsense if you know how matrix works. My theory is the matrix exposure scenes were adjusted for shooting chromes. Remember, everyone was shooting chromes when F100 came out. It all makes sort of sense if you think of how to expose for the chromes versus exposing for b&w. You will get underexposed shots for b&w in situations where contrast is wide (bright sky, dark woods for example). The only good cure is to use weighted average for exposure. I've never had exposure problems since I switched to weighted average.
