'Picky Details' for the Fujifilm FinePix 2650 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 Fujifilm FinePix 2650:
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.

Time to display a large/fine file after capture. Pretty fast.

| Shutter lag, full autofocus |

First time is at full wide-angle, second is full telephoto. About average. (Average is 1.0 seconds to a bit lower.) |
| Shutter lag, prefocus |
|
Time to capture, after half-pressing shutter button. A little faster than average. (Average is about 0.3 seconds.)
|
| Cycle Time, max/min resolution |
|
First number is for large/fine files, second number for small/basic images. Times are averages. A bit slow by current standards, the 2650 doesn't appear to use any "buffer memory" to reduce the cycle time. |
Overall, the FinePix 2650 is about an average-speed camera. It has a slightly slow shutter response in autofocus mode, but is a little faster than average when "prefocused" by half-pressing and holding the shutter button before the shot itself. Shot to shot cycle times are also a little slow by current standards, but not too bad overall. (The 2650 doesn't seem to use any buffer memory to keep the camera from having to wait for the memory card when shooting. This makes it a bit slower than average between shots, but also means that you can shoot until the card is full, without ever encountering any delays longer than the 2.7 seconds shown in the table above.)
Power
The FinePix 2650 uses two AA batteries for power. The table below shows the power drain and corresponding projected battery life in various operating modes.

Storage Capacity
The FinePix 2650 stores its photos on xD Picture cards, and a 16MB card is included with the camera. (I strongly recommend buying at least a 64MB card, preferably a 128MB one, to give yourself extra space for extended outings.) The chart below shows how many images can be stored on the included 16MB card at each size/quality setting.

Download Speed
The FinePix 2650 connects to a host computer via a USB interface.
Downloading files to a dual 1 GHz PowerMac G4 (OS X, version 10.2.3), I clocked
it at 195 KBytes/second. This is pretty slow as USB-connected cameras go.
(Cameras with slow USB interfaces typically run as low as 300 KB/s, cameras
with fast ones run as high as 600 KB/s.) If you wind up buying a really large
memory card for it, you might want to get an external card reader as well,
to avoid frustration while downloading image files.
