The problem with your wish list is that the telephoto end of small sensor super zooms is almost always diffraction limited, so no matter how fine the lens is, it will be soft. The only way around that is to keep the lens fast, i.e. f/2.8 or faster over the whole range and that makes a 40:1 zoom huge, even on a 1/2.3 sensor. The Panasonic ZS 300 is a 25:1, constant f/2.8 and is stays decently sharp over the full range, but then, again, it only has a 12MP sensor. If you go smaller pixels and longer zoom, the lens needs to be both faster and much bigger. Physics is a hard mistress. The Nikson P1000, which has an excellent lens is very soft at the long end at f/8 with a 16MP sensor. I have both the FZ300, and the P1000, so I understand the limitations of each. My R7 with a 200-800 that is f/9 at the long end provides much better detail thanks to the much bigger pixels not being as far into diffraction territory, but even there, diffraction is a big factor in the result. Bottom line, there is no point in wishing for something physics won't let you have.
