... the matrix meter is more sensitive to what's going on in the central area.
Say what? That's bad news? Yes, it is for those of you who've shot with the D70, D100, D200, D1 series, D2 series, or any of the Nikon film bodies. That's because all those other bodies are remarkably good at not being coerced into changing exposure based upon smallish non-middle gray things in the central area of the frame. The D50 was prone to changing exposure in those situations, and the D80 is even more prone to changing exposure due to middle subject tonal value. If you're not following me, try the following: cut a diamond shape (like the AF sensor pattern) out of white paper, middle gray paper, and black paper. (I'm having you use a diamond shape so that you'll frame them the same.) Now place each of those against a middle gray background, carefully framing so that the diamond exactly fits the AF sensor pattern. Voila: the gray background is underexposed with the white diamond in the center, properly exposed with the gray diamond in the center, and overexposed with the black diamond in the center. It's that last one that's problematic, in my mind. Overexposure means blown highlights that can't be recovered, and the D80 is going to be prone to do just that with the matrix metering system any time you've got darker-than-middle-gray subjects in the center of the frame. <snip>
The center-weighted and spot meters are their usual excellent selves, and the matrix meter, while a bit different than those that came before it, is predictable once you know what it's doing.
