"Picky Details" for the Konica Minolta DiMAGE X1 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 Konica Minolta DiMAGE X1:
|
||
|
(secs) |
|
Power On -> First shot |
|
Camera boots and LCD turns on.
|
Shutdown |
|
First time is simple shutdown, 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 |
0.22
|
Time to capture, after half-pressing shutter button. |
Cycle Time, max/min resolution |
4.95 / 4.0 |
First number is for large/fine files, second number is time for "TV" mode (640x480) images. Times are averages. In both modes, shoots this fast continuously, clearing the buffer afetr each shot. |
Cycle Time, Flash exposures | 6 | Flash at maximum power output. |
Cycle Time, continuous mode, max/min resolution | 1.86 / 1.41 (0.54 / 0.71 fps) |
First number is for large/fine files, second number is time for "TV" size images. Times are averages. At either resolution, shoots over 100 frames this fast, then clears the buffer in about 3 seconds. |
Cycle Time, Ultra High Speed mode, max/min resolution | 0.10 (9.9 fps) |
Times are averages. Shoots 15 640x480 frames, then clears the buffer in 11 seconds. |
Cycle Time, Multi frame mode | 0.30 (3.3 fps) |
Camera captures nine images, stores them in 3x3 arrays inside normal 2048x1536 files. buffer clears in 3 seconds. |
Power
The Konica Minolta DiMAGE X1 uses a custom rechargeable 3.7V, 820 mAh LiIon battery for power. Because it uses a custom power connector, we couldn't perform our usual direct measurements of power consumption, so instead have to rely upon Konica Minolta's published specs, based on the CIPA battery-life standard. (Which involves a combination of intermittent use, some zooming of the lens mechanism and firing the flash on 50% of the shots.) Using the CIPA protocol, Konica Minolta claims 150 shots for a fully-charged battery, and further report an approximate continuous run time in playback mode of 140 minutes. These aren't bad numbers for a subcompact digital model, but if you plan on any extended outings with the X1, you should definitely plan on purchasing a second battery along with the camera.
Storage Capacity
The Konica Minolta DiMAGE X1 stores its photos on SD / MMC memory cards, and a 32 MB card is included with the camera. (I strongly recommend buying at least a 128 MB card, preferably a 256 MB one, to give yourself extra space for extended outings.) The chart below shows how many images can be stored on the included 32 MB card at each size/quality setting.

Download Speed
The Konica Minolta DiMAGE X1 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 533 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.)
