The KX manual makes no mention of this, but since the metering is center-weighted, one function of that circle may be to point out the center that is weighted. I have also noticed that paying attention to that outer circle helps focus when the center aid conks out in low light, especially with longer lenses. If you have any light to focus by at all, give the KX a try. I find it very good in decent light.
