Timings & File Sizes

The Coolpix 775 is an average performer, it's not quite as zippy as it's bigger brother the Coolpix 995 or as some of the competition. There is a noticeable delay on power up, for some reason there's a 2.6 second delay between the power switch being engaged in the ON position and the lens beginning its extension.

Timing Notes: All times calculated as an average of three operations. Supplied CF card (Nikon brand 8 MB) was used for timings. Unless otherwise stated all timings were made on a 1600 x 1200 FINE JPEG image (approx. 720 KB per image).

*1 There is a 2.6 second delay between turning the power dial to 'ON' and the lens beginning its extension.
*2 Camera displays hour glass icon, then rough thumbnail full image is displayed (only for 1600 x 1200 images) about 2 seconds later (1600 x 1200 FINE).
*3 Time taken to display the 'rough thumbnail' after pressing the up or down arrows.
*4 Thanks to continuous auto focus mostly focus lag is less than 1 second, this can be a little longer for macro focus or at telephoto zoom

Compact Flash compatibility

Something I've not had to talk about before in my reviews is Compact Flash compatibility, in the processes of testing the Coolpix 775 I attempted to use a professional high capacity cards only to find that it wouldn't work, the camera displaying a 'THIS CARD CAN NOT BE USED' error, no amount of formatting would make the cards work.

The card that DIDN'T work:

  • Lexar Pro 12x 320 MB CF Type I

Other high capacity cards that DID work:

  • Delkin Devices 128 MB CF Type I
  • SanDisk 192 MB CF Type I
  • Kingston 256 MB CF Type I (High Speed)
  • SanDisk 512 MB CF Type I

Continuous drive mode

The table below shows the results of our continuous shooting test, indicating the actual frame rate along with maximum number of frames at a selection of image resolution / quality settings and how long you would have to wait after taking the maximum number of frames before you could take the next shot.

*1 Sixteen 400 x 300 images on a single 1600 x 1200 frame
*2 Frame rate drops to approximately 1.0 fps with LCD monitor on

Not a bad performance, especially for a camera which isn't targeted at shutterbugs. Switch the camera down to XGA (1024 x 768) and set compression to Standard and you can shoot up to 21 frames at 1.7 fps, very reasonable. Don't forget that these timings are with the LCD monitor switched off, expect a performance hit to see a review of each frame.

File Flush / Display Timing

Timings shown below are the time taken for the camera to process and "flush" the image out to the Compact Flash card, the timer was started as soon as the shutter release was pressed (shutter noise was heard) and stopped when activity indicator LED beside the viewfinder went off. 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 With JPEG it's difficult to predict the exact size of an image file 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.

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

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

Camera Battery Power Battery life Number of shots
Kyocera S3 BP-800S 2.1 Wh 54 mins 95
Canon Digital IXUS 300 NB-1L 2.5 Wh 1 hr 26 mins 155
Nikon Coolpix 775 EN-EL1 4.8 Wh 2 hr 27 mins 250
Fujifilm FinePix 6900Z NP-80 4.1 Wh 2 hr 29 mins 250
Nikon Coolpix 990 4 x AA NiMH 1600 mAh (GP) 7.7 Wh 2 hr 30 mins 255
Nikon Coolpix 995 EN-EL1 4.8 Wh 2 hr 30 mins 255
Canon PowerShot G1 BP-511 8.1 Wh 3 hr 00 mins 300
Sony DSC-S75 NP-FM50 8.6 Wh 3 hr 15 mins 330
Sony DSC-S85 NP-FM50 8.6 Wh 3 hr 50 mins 400

The Coolpix 775 performed almost identically to its bigger brother the 995, a respectable performance and a reflection of the power output of its battery. Notice how much more battery life you'd get out of the Coolpix 775 compared to Canon's Digital IXUS 300.
