I have a GX8 and it works beautifully with my 7-14mm Olympus lens. I do not get dual IS of course because the Oly lens has no IS, but you don't really need IS at all with a lens that wide. I also have the 20mm f1.7, 12-35 f2.8, 14-140, and 100-300. My only complaint about any of them is the relatively slow AF on the 100-300 and 14-140. I'm hoping the 100-400 will be faster as I am hoping to be able to dump my Nikon D750 and Tamron 150-600 birding kit.
