Page 7:Shutter Lag & Cycle Time Tests

Review First Posted: 8/17/2000

Shutter Lag/Cycle Times
When you press the shutter release on a camera, there's usually a lag time before the shutter actually fires. This time allows the autofocus and autoexposure mechanisms time to do their work and can amount to a fairly long delay in some situations. Since this number is almost never reported on, and can significantly affect the picture taking experience, we now routinely measure it using a special electronic test setup.
