Originally posted by morane_j MY opinion about build quality of Pentax products is not very good.
Gee, don't judge all Pentax product build quality on one experience with one lens, that's really unfair of you.
Bad luck for sure, but you need much more experience to make such a sweeping statement.
I had an 06 that failed after a week. Pentax sent me replacement right away, even before I sent the faulty one back. It's been fine ever since. As others have said, Pentax gear is solid and built to high standards.
My guess is that as the Q lenses are quite complex, electronically as well as really tiny components, there's bound to be some duds occasionally. These are the smallest interchangeable lenses made by anyone as far as I know, so don't be so quick to judge.
