Interesting site, thanks! Useful list of Oly 4/3 lenses.

Final question, please: what makes a lens "CDAF enabled"? I always thought the CDAF/PDAF stuff was all about the body's sensor, electronics, and firmware. I don't understand where the lens might come into it, doesn't the firmware just fire the lens focus motor for a step or two, re-evaluate the image, and repeat until lock?
