SR works by using servos that dectect camera body shake, and then apply negative feedback to the sensor positioning to counteract the body shake, thus putting the sensor back where it was before the body shook. The shake still occurs in the body, but effectively not in the sensor. Its not instantaneous or continuous SR, like a gyro or something, but its a fast enough servo system to do the job apparently. jco

Hey Folks, Can anyone 'splain to me how the K10D actually achieves the shake reduction feature? (And I don't mean how do I turn it on...heh heh) >From the perspective of a former astronomer, I'm just curious of how >this is being affected. Is the sensor somehow hooked up to some kind of inertial reference? Also, why does the manual tell you (over and over) NOT to use the shake reduction when the camera is on a tripod? There must be some kind of incompatibility....some times I'm shooting little critters with a big lens on an overly-small tripod, and I'm wondering if the shake reduction would help.... Barry A.
