Despite owning an F4(e), a couple of F5s and an F6, I have yet to ever use the "matrix" metering function on any of these cameras. Why not? Mostly because I prefer using manual focus lenses when shooting with my SLRs. Since the F5 does not allow use of matrix metering with manual focus lenses, and I often shoot with several bodies, I almost always have the cameras set to the same center-weighted setting. So, a couple of questions for owners of Nikons with matrix capabilities, and more narrowly, to those who shoot transparency films. 1. What is your overall assessment of matrix metering? 2. Are their particular shooting situations where you would avoid using the setting? 3. Are their any particular transparency films that do not lend themselves to matrix metering?
