K100D Focus hunt with DA16-45

Perhaps I have my camera settings wrong, but am having really bad issues with my lens whizzing in/out. I am not trying to focus on blue sky. I'm selecting objects that should have enough contrast.

Doesn't seem to happen with the kit lens.

Mine will hunt at the very widest angle or with very low contrast subjects. What focal length and lighting conditions are you shooting in>

No problem for me, may double check but it will lock most of the time, even in low light. I don't call it hunt because for me the term may imply not getting a focus.

It's wierd. I just took it out into my backyard and no issues, even pointed at partly cloudy skies. No issues.

But last week, scenes like these drove the lens batty.

I'd suspect the electrical contacts as well - and next time you get the hunt, try re-mounting the lens.
