I've read that they "evaluate" the entire image regardless of focus point to determine the main subject. Anyone else?
Elie is probably asleep right now, but I'm "anyone else".
Evaluative does evaluate the entire image, and the meter biases rather strongly to the chosen focus point.
I did some tests with my 30D - probably valid for your 5D also, since they're the same generation. Try it yourself and tell us what you find.
