I don't really think the lens is damaged either but it is a few years old so perhaps it's a combination of normal wear 'n tear and the better sensor pulling out both more details and defects, it hasn't been dropped or bumped into something. It doesn't happen in all photos but happens in more photos than with the K-5.
But reading through the answers it's most likely normal behavior. Thanks a lot!
I only shoot in RAW and it's really easy to get rid of the fringe in LR, the eye dropper tool is actually quite effective.
For the shots in my first post I used the Av mode and while the K-5 tends to underexpose in Av the K-3 seems to overexpose instead. Keep forgetting that as you can see in the background.
But it feels like the K-5 handles different lights (dark and bright in the same shot) better than K-3, at least when it comes to sunlit clouds. Perhaps the difference is that K-3 overexposes in Av mode, or I'm doing something wrong.
Btw, after using DA* 50-135 with K-5 and moving it to K-3 it was a step up, almost like upgrading the lens. The same journey with the Tamron had almost the opposite effect, I've always been quite impressed by the quality of the cheap Tamron but I liked it more with the K-5 than with K-3, would have like to had the same feeling with K-3 and Tamron as with DA*. If it's not a placebo effect of course.
If I would to upgrade to another normal zoom which to choose, DA* 16-50, Sigma 17-50 or perhaps a new Tamron 17-50?

EDIT:
It is common that the front element gets loose on these lenses. I have hade mine fixed.
Haven't even heard about this issue, checked some youtube clips and mine isn't nowhere near being as loose as the one's in the clips.
The big plastic ring which the lens hood attaches to moves about half a millimeter when wiggling it by hand.
