The latest Unified ML has both mirror lockup and intervalometer. However, can we somehow use them in conjunction so that the mirror is continuously up for the duration of the intervalometer use? Currently the mirror flips back down after every shot that the intervalometer programs the camera to take, but it would me much more quiet and convenient if it can be up all the time. This can reduce the camera shake in astrophotography time lapses while minimizing camera shake caused by the mirror movement. Also, the camera would be much quieter, which allows for an unobtrusive time lapse shot.
