Im curious, since I just acquired the 50-135... how do you know when SDM has failed? (this is my first SDM lens)
When it fails, the lens will not focus. It will get erratic for a while, then just give up. The one I used to have did that three times, and each of the first two times it spent 6 weeks in Pentax Canada's repair. The third time, I got rid of it. Superb glass, but for a sports lens, useless.
