"Picky Details" for the Fujifilm A340 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 A340:

Notes
|
| Power On -> First shot |
2.7
|
LCD turns on and lens extends forward. About average.
|
| Shutdown |
2.1 - 3.6
|
First time is time to retract lens, second time is worst-case buffer-clearing time. Fairly fast.
|
| Play to Record, first shot |
2.1
|
Time until first shot is captured. About average.
|
| Record to play |
4.3 / 1.7
|
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. A little slow.
|
| Shutter lag, full autofocus |
0.68/0.83
|
First time is at full wide-angle, second is full telephoto. Surprisingly fast for an entry-level camera. (But note that the A340 doesn't focus well in dim lighting.) |
| Shutter lag, prefocus |
0.19
|
Time to capture, after half-pressing shutter button. Quite fast.
|
| Cycle Time, max/min resolution |
2.20 /
1.57
|
First number is for large/fine files, second number is time for lowest resolution mode images. Times are averages. Buffer clears after each shot. About average. |
Provided it has enough light to focus with (see my comments in the main review
about night shooting), the Fuji FinePix A340 focuses and shoots a bit more
quickly than most of the competition. With a full-autofocus shutter delay
(the time between when you press the shutter button and when the shutter actually
fires) of 0.68 - 0.83 second, it's just a bit faster than the average range
of 0.8 - 1.0 second. While this still isn't fast enough to capture fast-breaking
action, if you "prefocus" the camera by half-pressing and holding
down the shutter button before the shot itself, the shutter delay drops to
0.19 second, a quite acceptable number. Shot to shot cycle times are decent
if not blazing, at 2.2 seconds per shot for large/fine images. Overall, a
surprisingly responsive camera, given the A340's entry-level pricing.
Power
The Fujifilm A340 uses two AA batteries for power.

With a worst-case run time (capture mode, with the rear panel LCD turned on)
of 124 minutes, the Fuji A340's battery life is on the good side of average,
especially for a camera powered by only two AA cells. With the LCD off, run
time stretches to just over 6 h ours, and is over four and a half hours in playback
mode. (All times are based on the use of 1600 mAh NiMH batteries. With modern
cells having true capacities of over 2000 mAh, your own run times should be
longer.) I do still strongly recommend that you plan on purchasing a good-quality
NiMH battery charger and a couple of sets of high-capacity NiMH rechargeable
AA cells right along with the camera though. Read my review of the Maha
C-204W to learn about my favorite charger, and check out my NiMH
Battery Shootout page for actual performance data on a wide range of batteries.
Storage Capacity
The Fujifilm A340 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 A340 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 780 KBytes/second, a very respectable rate, especially for an inexpensive
digital camera. (Digital 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.)
