Ah, but we *do* know for a FACT that the sensor is being cleared. The sensor is used to provide live preview on the LCD display, and needs to be cleared before being used to capture the real image. And, in any case, sensor spec sheets have been quoted here which give the exact clear time for the sensor (and which confirm that the sensor must be cleared before an image can be captured). Furthermore, just a reminder: my original post was made simply to try to put an end to speculation that the sensor clear accounted for any significant part of the total shutter lag - a theory which is totally contradicted both by sensor spec sheets and by empirical measurements.
