Definitions for "SHUTTER LAG"
One of the banes of digital photography. Shutter lag is the time it takes for the camera to set up the shot automatically for you, and in the process you may miss making the shot. Newer, faster cameras have addressed this problem. There are workarounds for older cameras, including holding down the shutter half-way until you're ready to take the picture, and using the Sports Mode or Burst Mode.
The time delay between the pressing of the shutter release and the actual taking of the picture.
The time between the shutter being pressed and the image captured. It can be a real problem when shooting moving subjects.
