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 an electronic test setup.

|
| Power On -> First shot |
|
Start with lens retracted. Time
is delay until first shot captured.
|
| Shutdown |
|
Time until lens is retracted,
camera is powered down. (No pending image processing though.)
|
| Play to Record, first shot |
|
Time is delay until first shot
captured.
|
| Record to play (max/min res) |
|
Slower for max res images
|
| Shutter lag, full autofocus |
|
Wide/Tele
(Wide is faster than tele) |
| Shutter lag, prefocus |
|
|
| Cycle time, Max/Min Res |
|
Quite fast, almost the same in high res as low. |
| Cycle Time, Continuous Mode (high/low resolution) |
|
Strangely variable cycle time in high resolution mode. |
