I've had SDM issues twice with my hard working DA* 50-135mm zoom, bought when the design was new more 10 years ago and also with my much newer DA* 200mm 2.8. both were fixed by Johnsons, the 50-135 twice, so far giving no further trouble.
Clocking up repair bills at Johnsons was far cheaper than replacing the lenses.
These lenses have been extensively used both before and after fixing, although the DA*200 has now been replaced (part exchange ) at SRS for the D FA* 70-200 which gives me much more flexibility.
More recently when the DA*16-50mm started to play up a very kind fellow PUF member who lives a few miles away and is more technically skilled than I am converted it to screw drive and its now as good as new.
