For the K10D, Pentax is claiming 2.5 to 4.5 steps of shake reduction effectiveness.
I have been wondering whether there are general conditions when one can get more shake reduction and when one can get less. For example, when I am in Europe I like to shoot inside cathedrals and other buildings. A typical setting is ISO 800, 1/30, wide open. Two steps of SR would get me down to 1/8, which is useful. Two more steps would get me to 1/2 second. But if the shutter is open that long, one might achieve correction for shake, but that is still enough time for light to register on the sensor in the wrong places. This would mean images that are blurry, have low contrast, or have ghosting. So, having not yet tried shake reduction, my thinking is that wide-angle, low-light shots will probably be able to use only 2-2.5 steps of shake reduction. The highest level of shake reduction, 4.5 steps, might be achieveable only with telephoto in daylight, where the shutter speeds would need to be higher to start with. What does everyone think?
