And that's not even a great zoom!
There is a lot of contrast in the image, providing a perception of sharpness.
About that previous image: No true black, not true whate, just shades of gray an pink.
Maybe it was taken in a steambath?
Like most bad lenses, it's pretty sharp in the center of view.

I'm with Reverand and the 24-70. This is what a good sharp zoom lens at full zoom (70mm) can do, and no I don't think if I used my 85 2.8 it would be any sharper:

Res too low to say much about the image.
Again, sharpest in the center, not as sharp in the edges (where they are in the plane of focus)
Cropping the center is like looking for leaks on the top of water tank, instead of the bottom.
"No leaks on top--must be OK"
To test a lens, you need to take a photo of a high contrast subject in very good light,
with detail throughout the image. And you can't compresss it.
And if you want to detect distoration, then you need some straight lines in the subject.
If these are the only kinds of photos you take, then you don't need a sharp lens.
To shoot a wedding, you don't need or want a sharp lens.
Maybe that's your point?
