A standard zoom with very small aperture. Very high distortion. Very high light fall off towards the corners. Mediocre sharpness especially in the long end. Very high CA.
How on earth does this lens deserve 3 out of 5 stars for its optics?
For instance the Tamron 17-50mm f2.8 VC, which scores better in all areas, gets 3 stars.

The difference is that you can see all flaws of the Tamron with conventional setups whereas the flaws of the Panasonic are hidden from normal mortals. The *** rating reflects this.
I can certainly see your point that this is unfair to some degree. If we rated it with -say- 2* on the basis of the uncorrected data we would have faced counter arguments from the MFT user group.
