Timings & File Sizes
Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 1600 x 1200 JPEG image (around 810 KB per image).
File Size Notes: 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.
When the CD1000 displays an image in play mode it displays a blue screen (with a frame counter) then displays the photo & details a few seconds later, this can be interrupted by pressing the 4-way controller left or right.

*1 Start up can take up to 14 seconds to finish "DISC ACCESS"
after changing CD-R.
*2 The 7.6s time includes time for CD-R to spin up, if you keep pressing left/right while the CD-R is spinning the image to image time is closer to 5.2 seconds. You can, at any time interrupt the loading of the image by pushing the 4-way controller left/right.
*3 This timing was made using the viewfinder, which showed a slight delay in update and thus probably added 0.1 seconds to the shutter release lag.
Not the fastest engine in the world, but usable. If you keep the CD-R spinning it's not too bad flicking between image in playback, but otherwise the CD-R spin-up time is noticeable.
* LAG times are often misunderstood and so are described below:
Auto Focus LAG is (roughly) the amount of time it takes the camera to autofocus (a half-press and hold of the shutter release button), this timing is normally the most variable as its affected by the subject matter, current focus position, still or moving subject etc. This timing is an average.
Shutter Release LAG is the amount of time it takes to take the shot after autofocus, this timing assumes you have already focused (half-pressed the shutter release) and now press the shutter release button all the way down to take the shot. This timing is an average.
Total LAG is the total time it takes (not just the two above added together) if you haven't pre-focused, that is no finger touching the shutter release button, press it all the way down in one movement, this new timing is how long it would take if you were in one of those spur-of-the-moment situations. This timing is an average.
Maximum Shots in a Row
Typically at this part of the review I'd be measuring the maximum number of shots you can take in a row before the cameras internal buffer was full, then how long you have to wait before that buffer is flushed out to the storage card before you can shoot again.
Just like the S70 & F505V the CD1000 doesn't seem to have very much internal buffer (if any) which means you can't "click click click" like you would with some of the competitions cameras (Coolpix 990, Olympus C-3030Z come to mind). You have to wait between shots, that combined with the slow Auto Focus system means that the quickest shot-to-shot times (at 1600 x 1200) are:
- Auto Focus: 4.5 seconds
- Manual Focus: 4.1 seconds
These times were defintely affected by the CD-R spin-up time. After taking a shot you can hear the CD-R spin-up and writing begins, in the mean time the camera does return control to allow you to shoot again but there's at least 1.5 seconds added to these times (compared to the F505V) thanks to the use of CD-R.
File Flush Timing
Timings shown below are the time taken for the camera to "flush" the image out to the CD-R.
|Store 1600 x 1200 TIFF||39.2||5,627 KB||25|
|Store 1600 x 1200 JPEG||5.5||~ 860 KB||160|
|Store 1600 x 1200 TEXT (GIF)||20.7||~ 30 KB||4,500|
|Store 1024 x 768 JPEG||5.5||~ 340 KB||420|
|Store 640 x 480 JPEG||5.5||~ 65 KB||2,200|
Not wonderfully fast. Because of the C1000's lack of a memory buffer the camera has to wait for the CD-R to spin-up before writing data out and releasing control back to the "shooting portion" of the camera. A simple write-back buffer would have solved this timing problem...
Thanks to the large InfoLithium battery pack, battery life on the CD1000 is great, especially if you're using the viewfinder (which automatically switches itself on and off). The manual estimates life at 100 minutes, we managed a little longer than that (about 115-120 minutes) by mostly using the viewfinder and switching the main LCD off.
