Olympus C-730 Ultra Zoom3.2 megapixels, a sharp 10x zoom lens, tons of features, and an affordable price!<<Exposure & Flash :(Previous) | (Next): Operation & User Interface>> Page 7:Shutter Lag & Cycle Time TestsReview First Posted: 11/25/2002 |
Shutter Lag/Cycle Times
When you press the shutter release on a camera, there's usually a
delay or 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, I now
routinely measure it with a custom test system I constructed for the purpose.
(With crystal-controlled timing, accurate to 0.01% and with a timing resolution
of one millisecond.)

(secs) |
|
Power On -> First shot |
|
Camera has to extend lens before the first shot. Rather slow.
|
Shutdown |
|
Time to retract camera lens. Also slow. |
Play to Record, first shot |
|
Time until first shot is captured. About average.
|
Record to play |
|
Time to display a large/fine file after capture. About average.
|
Shutter lag, full autofocus |
|
First number is for wide-angle, second is for telephoto. On the slow side of average. |
Shutter lag, manual focus |
|
Slower than average. |
Shutter lag, prefocus |
|
Time to capture, after half-pressing Shutter button. Faster than average.
|
Cycle Time, max/min resolution |
|
First number is for large/fine files, second number is time for small/basic images. Pretty fast. |
Cycle Time, continuous mode, max/min resolution |
0.93-0.76 |
First numbers are for large/fine files, second number is time for small/basic images. For some reason the interval between the first two shots in a series is greater than for subsequent ones. Buffer clearing time ranges from 10 seconds for large/fine series to 39 seconds for small/basic quality. Buffer capacity is ~7-8 shots at large/fine mode, ~138 at small/basic. Pretty fast overall. |
Cycle Time, TIFF images |
|
Typical for TIFF-mode images. |
The C-730 is an average to slightly slower than average camera overall. Startup
and shutdown are a little leisurely, as the telescoping lens mechanism is rather
deliberate in its motions. Shot to shot time is slightly over 2 seconds, not
bad, but not a category-leading performance either. It has a decent-sized buffer
memory though, helpful for grabbing relatively large numbers of shots in rapid
sequence. Autofocus speed is about average, although better than that of the
C-720, and not bad compared to some other long-zoom cameras. Continuous shooting
mode is a bit slower than average at roughly 1.2 frames/second. All in all,
not terribly slow, but a faster shutter response could have made this an excellent
camera for sports shooting, with its long zoom able to reach out to capture
distant action. As it is, unless you can prefocus the camera in advance of the
action, you'd have a hard time capturing critical moments. On the other hand,
if you're dealing with subjects where shutter lag isn't that important, the
C-730 gives great long-zoom performance at a bargain price.
