"Picky Details" for the Kodak EasyShare One 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 Kodak EasyShare One:
|
|
||
|
|
(secs) |
|
| Power On -> First shot |
|
LCD turns on and eventually lens extends forward.
|
| Shutdown |
|
First time is time to retract lens, second time is
worst-case buffer-clearing time.
|
| Play to Record, first shot |
|
Time until first shot is captured.
|
| Record to play |
|
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.
|
| Shutter lag, full autofocus |
|
First time is at full wide-angle, second is full telephoto. |
| Shutter lag, prefocus |
|
Time to capture, after half-pressing shutter button.
|
| Shutter lag, continuous autofocus |
0.25
|
- |
| Cycle Time, max/min resolution |
2.32 / |
First number is for largest files, second number is time for smallest files. Times are averages. Shoots 10 frames this fast in large mode, then slows to about 4.4 seconds per frame. Shoots 11 frames this fast in small mode, then slows to about 3.8 seconds per frame. Buffer clears in 25 seconds for either resolution. |
| Cycle Time, Flash exposures | 4 | (Flash at maximum power output) |
| Cycle Time, continuous mode, max/min resolution | 0.39 / 0.37 (2.58 / 2.68 fps) |
First number is for largest files, second number is time for smallest files. Times are averages. Shoots 5 frames this fast in either mode. Buffer clears in 22 seconds for large files, 18 seconds fro small files. |
Power
The Kodak EasyShare One uses a custom rechargeable LiIon battery for power.

Storage Capacity
The Kodak EasyShare One stores its photos on SD / MMC memory cards or in approximately 203MB of internal memory, and no 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 internal memory at each size/quality setting.

Download Speed
The Kodak EasyShare One 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 324 KBytes/second. (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.)
