afaik, only 1n, 1v, 1d, 1ds, and 3 do true af-spot linked metering.

Although apparently the 7D has some fancy thing where it will evaluate the metering of all points that are in focus or nearly in focus, and weight them more heavily when doing its 'full evaluative' metering. It's not true spot-linked, but it's closer than nothing. (someone want to clarify this? I'm at work and don't have a manual handy). And anyone know if the 5D3 does the same?
