IMPORTANT NOTE: I may go back to figure out the custom settings for this lens, but I don't recommend this combination FOR VIDEO use because the GX85 body does not have a manual focus dial, or an autofocus/manual focus switch (like the GX9) so you can quickly turn off AF. The reason you need this for video use, is that the AF is not reliable so it will "hunt" if you leave it on while recording. For instance, if you're in a documentary/interview/talking head situation it may switch from foreground focus to focus on the background, and that can ruin an interview (because you can't just make a person say something over, etc.) The workaround is to set the focus (on a person's nearest eye, typically) and then turn off AF. However, to do this on the GX85, you have to use the menu system instead of a physical switch (as on GX9). This takes too long and doesn't work in real situations. So, because the lens doesn't have a manual focus dial (or an on/off switch, I don't recommend this specific (lens-sensor) combination for video/filmmaking use (it's decent for still photography).
