Smaller image circle of a native M43 lens

Even though I have somewhat recently purchased a used GH4 for some video work, I am still a bit confused on what lenses will work with what manufacturers. I am considering buying the Panasonic Leica 8-18mm f/2.8-4 ASPH but I am also toying with the idea of getting the new Sony a7 III. This is a full frame camera so will the Leica 8-18mm still work on it or do I need another Sony equivalent lens? Still trying to figure out the mount system with micro 4/3.

Many thanks,
Houston

A native M43 lens, theoretically by a flange distance adapter (1.25mm) can be mounted on a Sony FF body. However, since the native M43 lens is designed to cover a much smaller image circle of a M43 sensor (25% of a FF sensor), serious vignetting (dark corner) must be occurred...
