Page 7:Shutter Lag & Cycle Time Tests

Review First Posted: 2/9/2001

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 is to allow 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.


Sony Mavica MVC-FD97 Timings
Operation
Time (secs)
Notes
Power On -> First shot
3.1/7.9
Time is delay until first shot captured. (Shorter time is with Memory Stick enabled: Camera needs to check floppy first, to see if there's space available.)
Shutdown
~0 - 21
No lens retraction to wait for, meaning zero shutdown normally. Max time is time until floppy may be removed if Text-mode image is being processed.
Play to Record, first shot
~0
Time is delay until first shot captured. Almost instant in manual focus mode.
Record to play (max/min res)
1.4, 3.2, 8.8, 21.0
Shortest time is for image already processed to floppy or Memory Stick. Next is for high res JPEG image just captured, using Memory Stick. 8.8 seconds is for JPEG to floppy. Longest is for text-mode image just captured, to floppy.
Shutter lag, full autofocus
0.60
Very fast.
Shutter lag, manual focus
0.4
A bit faster than average.
Shutter lag, prefocus
0.1
Faster than average.
Cycle time, max/min res
2.7/2.7
8.0/5.5
Shorter times are for Memory Stick, longer for floppy disk storage. (Memory Stick times are quite fast.)

 

Although the FD97 appears to use the same lens as the earlier FD95, we found it's shutter lag to be quite a bit less, and cycle times to Memory Stick are quite fast indeed. It appears Sony has used the intervening time since they introduced the FD95 to further improve basic camera performance. (All in all, a very good set of timing numbers.)
