No need to get sloppy, but no need to not rely on SR either. It does help.

There is in the case of the K-7 where the SR is so effective at 1/15 that the chances are higher to get a tack sharp image than they are around 1/100.

Actually, rotational shake is more problematic for longer focal lengths.
Originally posted by orly_andico ...and the SR can't compensate for rotational motion that well.
The SR mechanism can only compensate for rotational motion. Pentax cameras don't have sensors for translational shake.
