Panasonic really need to nail their AF so its near dual pixel AF on Canon or Sony's AF. I find apart from low light performance, thats my biggest issue with my G85 and the reason I'm hesitant to drop too much money on panny glass.
Olympus sure has good feeling AF in E-M1 MkII.
Just better to limit amount of AF points used from that ridiculous amount...
Because camera doesn't know what you're thinking and can decide that some other detail looks best target to focus.
Though nothing similar to (Konica)Minolta Dimage A2's "Center avoidance" AF:
Which had obsession to find some grass/tree branch/twig etc near edges, no matter how good target there was in center.
Really for as long as Panasonic insists on just trying to measure amount of blurriness they're going to stay behind.
All that can never give as fast accurate information for where to move focus as phase detection.
For start both back and front focus cause similar blurring/contrast decrease.
And if target's distance keeps changing that's another major complication, unless focus sampling rate/focus movement speed is enough faster.
These have about the best visualizations of operating principles of CDAD and PDAF.

Was looking for a WR lens for a Disneyland trip next month. I’ve got the 14-140 mk II for general travel purposes but it’s not weather resistant.
While really average in aperture m.Zuiko 12-100 is really nice general purpose zoom for minimizing lens swap need with rain expected.
(though after 4/3 Pana Leica 14-150mm long end is shorter feeling)
Had it few times "sniffing" rain in what little few thunderstorms there were in late summer... Or in that miserable excuse for summer.
With snow on ground now maybe there's finally going to be normal winter so that there's warmth left for next summer in "annual heat budget".
Month ago in storm chaser meeting heard about less succesful use of standard non-WR Canon/Nikon lens in rain:
Lens turned to manual focus lens...
