Junk.

It is pretty impressive for a camera lens with that zoom factor to get
even remotely close to diffraction limited at the long end. There was a
time when they struggled to do 3x zooms reliably not all that long ago.

Molded aspherical lenses, ED glass, faster computers to optimize design. But, the 3000mm is an "equivalent," a vile photography definition meaning that the sensor is so small it behaves as a FF camera would would with something like a 3000mm lens. In reality the actual lens in front of the small sensor probably is 500-600mm. Still, impressive range for a zoom, but then remember video cameras had the same thing long before still cameras.
