Originally posted by Gimbal I've read somewhere that the motors have been changed so that the problem now should be solved. I don't know if that matches with user experience though. Are there still problems with newer SDM lenses?
But it is not enough to have a HEARSAY that some motors were changed, I wan to know for sure! So, as Boris suggested, Pentax should admit the failures and make clear that new lenses are corrected as from some point.
If they do not wish to admit failures, at least they should make a clear change, say, announcing a new breed of SDM II, so that we could KNOW improvements have been made, and preferably also with a new ring type technology!
