Timing & Performance

The P700 was a pleasant surprise for us, it outperformed our expectations of it with good results in our usage timings and shooting. Startup time was above average although still took 2.6 seconds. Auto Focus also proved to be quick (perhaps thanks to the Hybrid AF system?) with fast AF lock and a reduced 'maximum time to auto focus'. Shutter lag (Half to Full press) was also impressively short, so quick in fact that we couldn't measure it except to say it's less than 1/10 sec. The only disappointment was the camera's continuous shooting capability which fell short of the specified shooting rate and what would be expected of a camera at this price point. Overall some Kudos to Casio, the P700 is a fairly quick snapper.

Timing Notes

All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 3072 x 2304 Fine JPEG image (approx. 4,000 KB per image).

Lag Timing Definitions

Half-press Lag (0->S1)
Many digital camera users prime the AF and AE systems on their camera by half-pressing the shutter release. This is the amount of time between a half-press of the shutter release and the camera indicating an auto focus & auto exposure lock on the LCD monitor / viewfinder (ready to shoot).
 

(Prime AF/AE)
Half to Full-press Lag (S1->S2)
The amount of time it takes from a full depression of the shutter release button (assuming you have already primed the camera with a half-press) to the image being taken.
 

(Take shot, AF/AE primed)
Full-press Lag (0->S2)
The amount of time it takes from a full depression of the shutter release button (without performing a half-press of the shutter release beforehand) to the image being taken. This is more representative of the use of the camera in a spur of the moment 'point and shoot' situation.
 

(Take shot, AF/AE not primed)

Continuous mode

The tables below show the results of our continuous shooting test, indicating the actual frame rate along with maximum number of frames and how long you would have to wait after taking the maximum number of frames before you could take another shot. Media used for these tests was a 512 MB Lexar 32x High-Speed SD card. Shutter speed was kept above 1/250 sec during these tests.

*1 You can take a frame as soon as there is space in the cameras internal buffer (writing continues "in the background").

Casio's specifications state that the P700's high speed mode shoots at three frames per second for up to five frames. We can confirm the five frame limit but our measured frame rate was just 2.1 frames per second (30% slower than specified). I'd also question the usefulness of a continuous shooting mode which can only shoot at around 0.6 fps.

File Write / Display and Sizes

Timings shown below are the time taken for the camera to process and "flush" the image out to the storage card, the timer was started as soon as the shutter release was pressed and stopped when activity indicator beside the viewfinder had gone out. This means the timings also include the cameras processing time and as such are more representative of the actual time to "complete the task".

*1 This includes processing time, with the P700 it was impossible to work out just how much of the timing was taken up by processing and how much was actual media write time. Judging by the size of the Fine JPEG files I'd guess that processing takes about one second.
*2 The P700 displays an image as quickly as you can press the left / right arrows on the four way controller, there is no perceptible delay.

If you compare these figures to those in our other seven megapixel group test reviews you'll have to bear in mind that the P700's JPEG's came out much larger (less compression) than the others. After shooting the live view returns just over two seconds later and writing continues in the background. The biggest surprise to us was just how long it takes to save a TIFF (not that many people will be doing that, why no RAW Casio?) Overall, considering the larger JPEG sizes the P700's throughput is average to slightly better than average, at the end of the day none of this gets in the way of taking the next shot. More impressive is its performance in play mode where the next image just appears instantly, Kudos.

Low Light Auto Focus

This test is designed to measure the minimum amount of light under which the camera can still focus. The focus target is our lens distortion test chart (shown here on the right), camera is positioned exactly 2 m (6.6 ft) away.

Light levels are gradually dropped until the camera can no longer focus. This is carried out at both wide angle and telephoto zoom positions (as more light reaches the focusing systems with a larger aperture).

Focal length
Aperture
at focal len.
Lowest light focus
Wide (33 mm equiv.) F2.8 -1.2 EV
Tele (132 mm equiv.) F4.0 -0.5 EV
Light intensity (Lux) = 2.5 x 2^EV (@ ISO 100), 10.76391 Lux = 1 foot-candle (fc)

The P700 doesn't have an AF assist lamp, although it does have an external AF sensor (a sort of approximate distance device used to increase AF speed). This means that of course the P700 can't focus in complete darkness, despite this it still proved to be fairly effective in dim conditions, even at telephoto zoom.

Battery life

We ran the camera through our new battery life test. This test is designed to be fair and comparative to each camera and battery type:

  • Take 4 shots without flash
  • Wait 2 minutes (50% of the time powering the camera off)
  • Take 1 shot with flash
  • Wait 1 minute
  • Repeat

Batteries are fully discharged and recharged before the test and all cameras were reset to their factory default settings. Here are the results:

Other test notes:
 • LCD monitor is left on during the battery test
 • The camera is powered off half of the time and left on half of the time (switch every 10 iterations)
 • There are now higher capacity AA NiMH batteries available, however in the interests of fair
    comparison we will continue to use our 1600 mAh test set

Considering the capacity of the P700's Lithium-Ion battery (just 4.5 Wh) the camera lasts remarkably well, lasting three and three quarter hours. In our table it's surrounded by cameras with much higher capacity batteries.
