    Hi Gerhard,
    You *still* will have shutter lag then. I first lock up the mirror, then press 
    the shutter button. That method still sees a lag. It is introduced in the camera

    * don't * do that I suggest. My previous (compact, not DSLR) camera's used such 
    a routine, and I suspected it to be repsonsible for some of the erratic results 
    my previous system put out every now and then. I feel that perhaps sometimes the 
    noise reduction routine "eats" part of the ends of the satellite trails.
    So in my photography, I don't use any noise reduction routine at all anymore.
    Good luck!
