"Picky Details" for the Kodak EasyShare DX6340 digital camera
(Timing, Power, and Storage Info)

Timing
I measure both cycle times and shutter delay times, 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 DX6340:

NOTE: My qualitative characterizations of camera performance below (that is, "reasonably fast," "about average," etc.) are meant to be relative to other cameras of similar price and general capabilities. Thus, the same shutter lag that's "very fast" for a low-end consumer camera might be characterized as "quite slow" if I encountered it on a professional model. The comments are also intended as only a quick reference: If performance specs are critical for you, rely on the absolute numbers to compare cameras, rather than my purely qualitative comments.

Operation
Time
(secs)
Notes
Power On -> First shot
5.75
Time for lens to extend and startup screen to disappear. Fairly slow.
Shutdown
3.14
Lens retracts. Also somewhat slow.
Play to Record, first shot
1.3
Time until first shot is captured. Average to a bit faster than average.
Record to play
1.2
Time to display a large/fine file after capture. About average.
Shutter lag, full autofocus (wide/tele)
0.647/0.998
Faster than average with the lens set to its wide-angle position, about average at telephoto.
Shutter lag, prefocus
0.164
Time to capture, after half-pressing shutter button. Fairly fast.
Cycle Time, max/min resolution
2.1 / 2.08
First numbers are for large/fine files, second number is time for small/basic images. Fairly fast. The camera captures three high res images quickly, but slows to ~5-6 seconds afterwards. In low-res mode, the camera captures five images before slowing.
Cycle Time, continuous mode, max/min resolution
0.36 / 0.36
(2.7 fps)
First pair of numbers is for large/fine, second set for small/basic files. Number beneath is frames per second. Camera captures four frames continuously before pausing to write the images to the memory card. Four frame limit applies regardless of image size.


The DX6340 is about average in most of its performance characteristics. Shutter lag is better than average in wide-angle mode, and just on the slow side of average at telephoto. Cycle times are fairly good, and continuous-mode cycle time is quite good too. On the down side, startup is decidedly sluggish.

 

Power
The DX6340 uses two AA cells or one CRV3 lithium battery for its power source. (I recommend high-capacity NiMH cells, coupled with a good charger. Read my NiMH Battery Shootout page for the latest on actual battery performance, or my review of the Maha C204F to see why it's my favorite charger.) The table below shows the DX6340's power consumption in various modes, and approximate run times for each, based on a set of NiMH batteries with a (true, not advertised) 1600 mAh capacity:

The DX6340's battery life is a bit of a mixed bag: With the LCD on in record mode, battery life is pretty short, a bit over 80 minutes with true 1600 mAh capacity NiMH AA cells. On the other hand, battery life with the LCD display off is exceptional, nearly 14 hours. It does pretty well in playback mode too, with a projected life of about 3 hours. Still, I strongly recommend that you pick up a couple of sets of high-capacity NiMH batteries and either a separate charger, or Kodak's EasyShare dock, which serves as a battery charger as well.

 

Storage Capacity
The DX6340 stores its photos on SD memory cards, or its 16 megabytes of internal memory. (I strongly recommend buying at least a 32MB card, preferably a 64MB one, to give yourself extra space for extended outings.) The chart below shows how many images can be stored in the camera's 16 megabytes of internal memory at each size/quality setting.

Download Speed
The DX6340 connects to a host computer via either a USB interface or the accessory EasyShare camera dock. Downloading files to my Sony VAIO desktop, 2.4 GHz Pentium IV, running Windows XP ("VAIO"), I clocked it at 512 KBytes/second. (Cameras with slow USB interfaces run as low as 300 KB/s, cameras with fast ones run as high as 600 KB/s.)
