I'm not sure what you mean by auto-metering.
If you use a Nikon mount via an adapter, the Canon XSi will still meter. It will be "stop-down" metering using the ap ring rather than the on-camera dial. You will lose the focus confirm in the viewfinder though. Not a problem if you focus using live view. Also the viewfinder will get dim as you stop down.
