The quietness aspect has never been an issue for me as usually surrounded by spectators shouting encouragement. A different story for the wildlife shooter no doubt.
Have lost shots in the past when the AF (istD/K10D) could not keep up with the changing distance. So if this lens helps then a trip to SRS in May will be in order.

Innovative SDM System for smoother, quieter autofocusing operation
These two new SMC PENTAX-DA_ zoom lenses come equipped with a new SDM System, which assures smoother, quieter autofocusing operation using a built-in supersonic motor. When mounted on the PENTAX K10D digital SLR camera body, the focus mode is
automatically switched to SDM-assisted autofocusing. When mounted on other PENTAX digital SLR camera bodies, the conventional autofocus mode using a camera-mounted motor is selected.
Question.
Do the SDM lenses focus quicker than non SDM lensesl?
I shoot quite a few running events over the year by its nature I am shooting a moving target usually closing in on me. Therefore if a SDM could maintain continous focus that would be great.
Does anyone have any thoughts or experience in this field with this lens?
