Ah, I see what you're talking about now... The Focus Confirmation Indicator in the Pentax DSLRs is the green LED at the bottom of the screen, outside the image area. The Focus Point Overlay in the Pentax DSLRs are the red LED points that light up on the screen itself, in conjunction with the FCI, when AF has locked in. With manual focus lenses, if the overlay is enabled, the center one only will always light when the FCI is lit. The operation of the Focus Point Overlay in Pentax DSLRs is independent of the focusing screen. Canon DSLRs use small protrusions or depression on the focusing screen itself to provide the light point, so they require that a focusing screen have these bits in place to operate.
