This stems from some early problems with a design fault in a couple of SDM lenses and it was tackled years ago by Pentax. There will always be some failures of any item, but SDM should be as fine as any other focusing system motor. WE haven't heard much about the issue for a very long time.
I am concerned because I am thinking of a DA*200mm lens.

When talking about curved sensors I presume it is actually spherical, a one plane curved sensor would be a lens makers nightmare.

Heavens Gwyn, that's even worse!
Over the Christmas holidays we've been playing 'Travelling sprout's.
Basically a sprout has been left hidden in full view, the finder moves it to e new location, where it's sticky in full view. The next finder does the same again, and so on.
Childish, stupid and good fun.
Finally, tonight, the sprout made it's last trip, into the stove...
