Here are some camera specs (Oly E-520). What does the underlined message below mean exactly? Doesn't work with Live View?

AF system TTL phase-difference detection AF, High-speed imager AF*1
Focus mode Single AF (S-AF) / Continuous AF (C-AF) / Manual Focus (MF) / S-AF + MF / C-AF + MF
*Continuous AF is not available with the High-speed imager AF
Focusing point 3 points (TTL phase-difference detection), 11 points (High-speed imager AF*1)

Anyone? Does it have to do with AF in low light?

I check it and it does not seem to be "light related".

It says:

AF system TTL phase-difference detection AF, High-speed imager AF*1
And then:

*Continuous AF is not available with the High-speed imager AF

So AUTOFOCUS is not available with the High-speed imager...but I can't see what the Hight-speed imager AF*1 does...

Oly's "Hi Speed Imager" is a mode that allows their "live" LCD screen to respond in real time. It's drawback is that you can't use continuous AF while using HCI because the two conflict with each other. Something like that. Lenses need to be specifically designed for HCI to be used with this feature, and it's a separate autofocus mode, as I understand it.
