Thank you very much for this - It is good that they compared the logical choices. I would love to have seen the 16-50 to round out the group, but I guess then they would have to have looked at the 16-45mm as well, and the 18-250mm, which this lens replaces.
I'm actually sold, for me the slight letdown in sharpness is made up for in colour rendition, bokeh, range, weight and size, very fast, silent focus (It focuses fast on the K-7 too - just tried it) and generally good distortion and CA control.
This is a much, much better lens than the historical FA 28-200mm I used to have.
As to the decentering - it is a bit of a letdown, but how many group elements does this have (11)?
Sorry, one more quibble, no distance scale or Hyperfocal markings.

Reason: decentering comment.
