Makes me glad I have an 18-250 with good old fashioned, and reliable, screw drive technology. Now, if it's really DC technology like the 18-135WR that is a completely different story.
My SDM 18-135 already outlasts my 18-250 by Tamron... Although I must admit it is not the screwdrive that failed but twice already the aperture lever sticks... And coincidence or not, when that happened the same thing happen4d to my up till then trusted and much appreciated Tamron 28-75/2.8. What a lens that was, but not sealed
.
Now that I think of it, I never got excited about the idea of FF Pentax, just not for me, but if that may lead to a sealed DFA* 20-70/2.8 I will be the first to order... (the 28-70 that is...)
