"Picky Details" for the Fujifilm FinePix S5100
digital camera
(Timing, Power, and Storage Info)
Timing
When you press the shutter release on a camera, there's usually a lag time
or delay before the shutter actually fires. This corresponds to the time required
for 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 rarely
reported on (and even more rarely reported accurately), and can significantly
affect the picture taking experience, I routinely measure both shutter delay
and shot to shot cycle times for all cameras I test, using a test system I designed
and built for the purpose. (Crystal-controlled, with a resolution of 0.001 second.)
Here are the numbers I collected for the Fujifilm FinePix S5100:

Time

Notes
|
| Shutdown |
3.9 - 7
|
First time is time to retract lens, second time is worst-case buffer-clearing time. A little slow, but not too bad.
|
| Play to Record, first shot |
3.7
|
Time until first shot is captured. A little slow.
|
| Record to play |
2.9 / 1.6
|
First time is that required to display a large/fine file immediately after capture, second time is that needed to display a large/fine file that has already been processed and stored on the memory card. About average for this class of camera.
|
| Shutter lag, Full Autofocus |
0.83/0.79
|
First time is at full wide-angle, second is full telephoto. About average, not bad for a long-zoom digicam. |
| Shutter lag, Continuous Autofocus |
0.98 |
As is usually the case, continuous AF doesn't help at all with static subjects, and actually slows shutter response somewhat. (Rather slow.) |
| Shutter lag, Manual Focus |
0.57 |
On the slow side for manual focus. |
| Shutter lag, Prefocus |
0.055
|
Time to capture, after half-pressing shutter button.
|
| Cycle Time, max/min resolution |
1.94 /
1.82
|
First number is for large/fine files, second number is time for "TV" mode (640x480) images. Times are averages. No buffer to fill/clear, all shots are this fast. Not blindingly fast, but not too bad, either. |
| Cycle Time, "Top 3"
mode |
0.29
(3.45 fps) |
Shoots a burst of 3 images at the same rate in large/fine mode or "TV" mode. Times are averages. Buffer clears in 4.9 seconds for large/fine images, 3.4 seconds for lowest resolution. Very fast. |
| Cycle Time, continuous mode,
max/min resolution |
0.81 / 0.67
(1.23 / 1.49 fps) |
First number is for large/fine files, second number is time for small/basic images. Times are averages. Shoots up to 40 images in either resolution and clears the buffer in about a second. Fairly fast, particularly considering that it can shoot more or less indefinitely at this rate. |
Average shutter lag and cycle times. With full-autofocus shutter
lag times ranging from 0.79 - 0.83 second, and shot to shot cycle times for
large/fine images just under two seconds, the Fuji S5100 comes is a pretty
average performer - neither greatly faster nor greatly slower than much of
its competition. It's very fast when "prefocused" by half-pressing
and holding down the shutter button prior to the shots itself (a shutter lag
of only 0.055 second), and cycle times in its "Top 3" continuous-shooting
mode are very fast at 3.45 frames/second, albeit only for three frames. Overall,
not a bad camera, performance-wise, and potentially very useful for sports
shooting, if you can take advantage of its fast prefocus response and good
speed in Top 3 continuous mode.

Really excellent battery life! With a worst-case run time of just under
four hours with a "standard" set of 1600 mAh NiMH rechargeable batteries
(and proportionately longer with modern, high-capacity cells), the Fuji S5100
has some of the best battery-life numbers of any camera currently on the market.
(Run time in playback mode is an astonishing 7.45 hours.) You'll still want
a couple of sets of good-quality NiMH
batteries and a good battery
charger, but the S5100 will run a long time on a single charge.
Storage Capacity
The Fujifilm FinePix stores its photos on xD memory cards, and a 16 MB card
is included with the camera. (I strongly recommend buying at least a
64 MB card, preferably a 128 MB one, to give yourself extra space for extended
outings.) The chart below shows how many images can be stored on the included
16 MB card at each size/quality setting.

Download Speed
The Fujifilm FinePix connects to a host computer via a USB interface. Downloading
files to my Sony desktop running Windows XP (Pentium IV, 2.4 GHz), I clocked
it at 932 KBytes/second, a pretty good rate. (Cameras with slow USB interfaces
run as low as 300 KB/s, cameras with fast v1.1 interfaces run as high as 600
KB/s. Cameras with USB v2.0 interfaces run as fast as several megabytes/second.)
