The best Lumix cameras have Leica lenses. Read the lens maker id on the ring surrounding the front lens element. The non-Leica lenses are very good, but the Leica are better. I'm not sure there are any "superzooms" left that don't take video.
Don't include "digital zoom" in your desired zoom range. It's just a spin on cropping, and those small sensors don't need to be any smaller.
