Timing & Performance

Your first impression of the F700 must be its speed and responsiveness, the camera powers on and off very quickly with one of the fastest extending lenses I have ever seen. Auto focus was also very fast, in good light taking just half a second at either wide angle or telephoto. Off to shot taken and shot to shot times were both extremely good, much better than we would expect, the only disappointment may be the 0.2 second shutter release lag when using the LCD monitor (due to the delay introduced by the monitor's live view). One action which is simply too slow is playback magnification which takes an eternal 6 seconds to reach full magnification. Otherwise this is one of the fastest consumer cameras you can buy!

Timing Notes

All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 6mp (2832 x 2128) JPEG image (approx. 1,500 KB per image). The media used for all the tests on this page was a 128 MB Fujifilm xD-Picture Card.

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 table below shows 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.

Top-5 (6M / 3M / 2M) 4.2 fps 5 2.6 sec
Last-5 (6M / 3M / 2M) 4.2 fps 5 2.6 sec
Long Period (1280 x 960) 1.8 fps 40 0.8 sec

*1 In a single "burst" (finger held down on shutter release)
*2 The F700 won't let you take the next burst of shots until the currently buffered burst has been written to the xD card. This timing is from the display showing 'Storing' to the live view returning.

Oddly the F700 shot slightly slower than its specified 5 frames per second, even so four frames per second from a consumer level digital camera is extremely good. The F700 was also very fast to finish writing the burst of five shots, allowing you take the next five. The 'Long Period' shooting mode is limited to 1M (1280 x 960) image size only, however it does allow up to fourty frames at 1.8 frames per second. The other thing that is impressive about the F700's continuous shooting mode is that it does not blank out the LCD, in whichever mode it continues to provide a display of the scene (either live or the briefly shot just taken).


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 LED beside the viewfinder stopped blinking. 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 All file sizes are an average of three files. As is the case with JPEG it's difficult to predict the size of an image because it will vary a fair amount depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect.
*2 Camera estimation.

The F700 has very short processing and write times, just two seconds at the six megapixel output size is impressive, and playback display is almost instantaneous. Kudos Fujifilm.


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).

This test target is the optimum type of subject for most "contrast detect" AF systems (as it has a vertical line at its center), you should consider the results below the best you could expect to achieve.

Lens position Aperture Lowest light focus
Wide angle (35 mm equiv.) F2.8 Complete darkness
Telephoto (105 mm equiv.) F4.9 1.7 EV (8.1 Lux, 0.75 foot-candle)

Light intensity (Lux) = 2.5 x 2^EV (@ ISO 100), 10.76391 Lux = 1 foot-candle (fc)

The F700 has a green LED AF assist lamp, it's fairly weak and in our tests was offset downwards from the center of the frame. The lamp appears to work well at wide angle but the smaller aperture at telephoto meant that it wasn't powerful enough on its own to produce a bright enough image for the AF system, thus a little extra light will be required at telephoto.
