Yes, I was thinking about returning it, because maybe it's just a bad copy...
I found this lens in version
18-55 WR II, like it is mine, was marked in overall scores as less sharp then its original, first vesion... Mine have silver, and older version green ring...
When I purchased this camera, I was reading reviews about this lens ( obviously most of them of the older, or non
wr version ), and find it can be decent for a start, but I was surprised with overall softness in my pics.
I imported some of the pics in
photoscape ( very simple editing program with lot of features, I recommend it highly as an fast and very good alternative )
and I just add some sharpness - and pics was much much better immediately ...
At first,
I was not sure what is the reason, because maybe files from Pentax are little soft, which is also known fact.
I visited the store here, and attach some other lens on my Pentax K3 body, and yes, the results was better.
My conclusion
I found the lens, which are weak in sharpness are not good solution for camera of this high resolution, simply because you can zoom your picture so much, and every, even tiny blur is much noticeable, if you pair your pics with 16 Mp, or lower sensor jpegs.

That's why I immediately order one Sigma 17-70 2.8-4.5 Macro, and Pentax DA 35 2.4, which is, from what I read here best bucks and excellent in sharpness...
