Have tried many Lumix & Olypus lenses but ended up with:
Panasonic Leica 8-18
Panasonic Leica 12-60
Panasonic Leica 100-400
& Panasonic Leica 15 for low light & low weight
All used on Olympus OMD E-M1 II
Recently sold off:
Lumix 12-35 2,8
Lumix 35-100 2,8
It is interesting, even as recently as when this thread started, to note how as a lot of these new lenses are being released, some of the old standby combinations are starting to fall out of favor with some people. The Lumix 12-35 & 35-100 f2.8s and the Oly 12-40 & 40-150 PRO combos for instance. For years those where kind of the standard high end combos everyone was getting. Then they start released things like the Oly 12-100 & 8-25 PROs or the Leica 8-18 & 12-60 for example and it seems a lot of people are switching up their kits. Same on the longer focal length.
Soooooo many choices now. It's a good thing of course, but if people were racked with indecision 5 years ago, oh boy, these days it is only getting worse.
