"Picky Details" for the Konica Minolta DiMAGE X60 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 X60:

Notes
|
| Power On -> First shot |
1.6
|
LCD turns on and lens extends forward.
|
| Shutdown |
1.9 - 11
|
First time is time to retract lens, second time is
worst-case buffer-clearing time.
|
| Play to Record, first shot |
1.9
|
Time until first shot is captured.
|
| Record to play |
4.1 / 1.3
|
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 |
0.95 / 0.88
|
First time is at full wide-angle,
second is full telephoto. |
| Shutter lag, prefocus |
0.131
|
Time to capture, after half-pressing shutter
button. |
| Cycle Time, max/min resolution |
2.33 /
2.48
|
First number is for large/fine
files, second number is time for "TV" mode (640x480) images.
Times are averages. In large/fine mode, shoots 6 frames this fast, then
slows to about 3 seconds per shot. In TV mode, continues at this rate
seemingly indefinitely. Buffer clears in 5 seconds for large/fine images,
2 seconds for lowest resolution. |
| Cycle Time, Flash exposures
|
6 |
Flash at maximum power output. |
| Cycle Time, continuous mode,
max/min resolution |
0.65
(1.55 fps) |
First number is for large/fine files, second number is time for "TV"
size images. Times are averages. Cycle time is 0.65 seconds for three
frames, regardless of resolution. Buffer clears in 7 seconds for large/fine
images, 6 seconds for lowest resolution.
|
| Cycle Time, Multi Frame mode |
0.67 / 0.63
(1.49 / 1.59 fps) |
First number is for large/fine
files, second number is time for "TV" size images. Times are
averages. Camera captures 9 images, stores them in 3x3 arrays inside normal
files. Buffer clears in 7 seconds for large/fine images, 6 seconds for
lowest resolution, and it's set for another burst. |
Power
The Konica Minolta DiMAGE X60 uses a custom rechargeable LiIon battery for
power.

Storage Capacity
The Konica Minolta DiMAGE X60 stores its photos on SD / MMC memory cards
or in approximately 15 MB 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 in the internal memory at each size/quality
setting.

Download Speed
The Konica Minolta DiMAGE X60 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 751 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.)
