"Picky Details" for the Nikon Coolpix P1 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 Nikon Coolpix P1:
|
||
|
(secs) |
|
Power On -> First shot |
|
LCD turns on and 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, continuous autofocus |
|
Rarely any faster than normal autofocus, at least for stationary subjects. (We have no way of reliably testing shutter lag with moving subjects.)
|
Shutter lag, limited focus range, telephoto |
0.69
|
Slightly faster than normal autofocus with the lens at telephoto focal lengths. |
Shutter lag, prefocus |
0.074
|
Time to capture, after half-pressing shutter button. |
Cycle Time, max/min resolution |
3.17 / 3.03 |
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. In large/fine mode, buffer fills slowly, and clears in 13 seconds. In TV mode, buffer clears after each shot. |
Cycle Time, Flash exposures | 6 | Flash at maximum power output. |
Cycle Time, continuous High mode, max/min resolution | 0.44 (2.2 fps) |
Times are averages. Cycle time is 0.44 seconds for five frames, regardless of resolution. After a pause of 7 seconds in large/fine mode, it slows to about 3.2 seconds per shot. After a pause of 6 seconds in TV mode, it slows to about 2 seconds per shot. Buffer clears in 7 seconds for large/fine images, 6 seconds for lowest resolution. |
Cycle Time, continuous Low mode, max/min resolution | 0.56 (1.8 fps) |
First number is for large/fine files, second number is time for small/basic images. Times are averages. Shoots 11 frames this fast in large/fine mode, or over frames in TV mode. Buffer clears in 10 seconds for large/fine shots, in 6 seconds for TV mode images. |
Cycle Time, Multi 16 mode | 0.60 (1.66 fps) |
Camera captures sixteen 816 x 622 pixel images, stores them in 4x4 arrays inside normal 3264x2448 files. Buffer clears in about a second. |
Cycle Time, Ultra High Speed mode | 0.03 (30.3 fps) |
Times are averages. Shoots up to 100 640x480 images at 30 fps. Buffer clears in 18 seconds. |
Cycle Time, 5-shot Buffer mode | 1.17 (0.86 fps) |
Shoots at this rate continuously while shutter button is depressed, and records only the last five frames after the button is released. Buffer clears in 7 seconds. |
Power
The Nikon Coolpix P1 uses a custom rechargeable LiIon battery for power, so we were unable to perform our usual power measurements. Using the CIPA standard, Nikon claims approximately 180 shots on a fully charged battery for it, a number that's a bit on the low side. - And WiFi usage undoubtedly takes more power to drive the radio link. (We managed to completely drain a fresh battery in just over an hour of playing with the camera, with WiFi active about half of the time.) Overall, our standard recommendation that you purchase a second battery right along with the camera applies doubly to the P1.
Storage Capacity
The Nikon Coolpix P1 stores its photos on SD / MMC memory cards or in approximately 29 MB of internal memory, and no 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 in the internal memory at each size/quality setting.

Download Speed
The Nikon Coolpix P1 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 493 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.) Transfers via the WiFi connection are a little slower. We clocked the P1 at about 350 Kbytes/second on a purely "G" WiFi network, and about 225 Kb/sec when both B and G devices were active.
