| *1 | There is a 2.6 second delay between turning the power dial to 'ON' and the lens beginning its extension. |
| *2 | Power off takes 5.2 seconds if lens is at telephoto position. |
| *3 | Subsequent zoom levels take approximately half a second. |
| *4 | At either wide angle or telephoto with sufficent light. If auto focus can't lock it may take up to a second longer before the red dot appears. |
| *5 | Instant playback disabled, must wait for focus brackets to re-appear before pressing shutter release otherwise shutter release is locked. |
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.

| 640 x 480 STANDARD | ~1.0 fps | - | - |
| *1 | You can take a frame as soon as there is space in the cameras internal buffer (writing continues "in the background"). Timings taken using the supplied Nikon branded SanDisk CF card. |
For some odd reason the S304 actually slowed down for smaller size (file size) images in continuous mode, however at anything less than 1600 x 1200 STANDARD the frame rate and write speed of the CF card 'broke even' which means you can just about shoot until the card is full (but only at one frame per second).
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 click was heard) and stopped when activity indicator LED beside the storage compartment went 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". Supplied CF card (Lexar 8x 16 MB) was used for timings.

| *1 | Instant playback disabled. With instant playback enabled CF writing only starts once the playback image has been displayed, thus either 2 or 10 seconds after the image has been taken and processed. |
| *2 | Screen is blank and camera is inoperative during writing period. |
| *3 | The S304 displays all images almost instantly in 'browse' mode (pressing the 4-way controller left or right to view images), the only delay (actually reading the image) occurs if you press the magnify button. You can not magnify TIFF images. |
| *4 | 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:
About what we've come to expect of AA powered digital cameras, approximately 2.5 hours. Interesting to note that the S304 did considerably better than its bigger brother the DiMAGE 7. It also got less hot (although still warm).
