I know that it's very important to raise the value to minimize or eliminate shutter vibrations. However, I also recalled reading that after a certain period of time, regardless of whether the mirror is raised or not, the image should still be sharp provided a good tripod/ballhead setup is used. Does anyone here happen to know at which shutter speeds would raising the mirror be of any use to me?
