- SDM failure rates are monitored and do not exceed those of other components, - Pentax is aware of the buzz about the issue but considers it unjustified, - not every perceived failure necessarily is one. SDM motors hold a charge which depletes after prolonged (months) non-use. Once discharged, the lens will no longer focus. The charge takes up to two minutes to rebuild, i.e. the lens needs to be left alone for that time while connected to a powered on camera. At times, that may still not be enough to initially overcome mechanical stiction from the long sitting period. Joseph did the right thing basically,
But this sounds like BS. Never heard that lenses from other manufacturers, such as Canon, Nikon, Sigma, Olympus to name a few, suffered this charge-discharge phenomenon.
