The DFD will work better with Panasonic lenses, and yes, a full profile will realize the full benefit. However, as the Japanese GX850 brochure states, there's a partial DFD benefit even using non-Panasonic lenses (which does include Olympus lenses).

I already did that before. Go ahead to Panasonic's Japanese website, go to their section on GF9, and translate the Japanese text. It's their Japanese website, not the PDF brochure (my small mistake):

http://panasonic.jp/dc/g_series/gf9/high_image_quality.html

The link you provided is to a pdf brochure on the GF9.  The section on 空間認識AF does not mention other cameras.  It's hard to find the reference you quote below on the Panasonic site.  Perhaps if you quoted more of it in Japanese, to allow for a search?

I'm also interested in this topic in regard to using Oly lenses on my G9.

Translate the section on AF- look for "空間認識AF"

"Improve autofocus speed and tracking performance

Adopt space recognition technology (DFD * technology) to instantaneously calculate the distance to all subjects appearing on the screen. Contrast AF which high precision was popular in the past, has also realized faster AF (autofocus) and improved tracking performance. In GF 9, even when using micro Four Thirds lenses other than ours, we can improve AF performance by utilizing a part of DFD technology.

* Abbreviation for Depth From Defocus."

Emphasis mine. You are welcome
