Buying the DA* 50-135 SDM with k100d

I'm quite interested in buying the DA* 50-135 SDM. However, I am concerned about the SDM failures.

Mostly I'm worried it'll fail within warranty, without me knowing, because my K100d doesn't have SDM. That, or the SDM function will fail rapidly when I do get a SDM compatible body.

Just thought I'd see if anyone had thoughts or suggestions on this; the lenses I really want are all bloody SDM, but I can't justify upgrading bodies as of yet...

This is a common question. You will hear from people who had problems with sdm and those who have not. You are likely to be back where you began.

Just checked Adorama, they are selling a Mack 7 year warranty for 34.95, a bargain. I did get extended warranty with mine.

If you are using the K100 I don't see how the sum would fail as there is jmo power to it. Unless it failed mechanically there should be no proble

WHERE is this $35 7 year warranty for DA* glass at Adorama? This kind of a bargain on a warranty, if it is a good warranty and won't prove to be a PITA, would make me change my mind on the DA* 16-50....but I see 3 year warranties for a lot more than that, help me out! Thanks!
