Timing & Performance
Although the user interface can make the S10 feel a little sluggish if you're using the more advanced features regularly, it is broadly offering the same performance as the other cameras in this class (and is certainly better than other Coolpix cameras we've tested recently).
Our one big complaint is focus speed, specifically at the long end of the zoom with anything other than an ideal subject. In low light or at short subject distances the focus hunting at longer focal lengths can drag out to two seconds or more, which seriously limits the usefulness of the camera for any non-stationary subjects. For less demanding subjects, and when using the wider end of the zoom in daylight the focus is not significantly slower than any other big zoom compact, and shutter lag is just the right side of 0.1 seconds.
All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 3264 x 2448 Fine JPEG image (approx. 3,100 KB per image). The media used for these tests was a 1.0 GB Sandisk Extreme III card.

|*1||Low res previews are loaded in around 0.1 seconds, so you can scroll through images fairly quickly. The time mentioned above is to load the full image.|

|*3||Focus times vary widely from about 0.45 to 2.05 secs (telephoto), depending on the brightness and contrast of the scene. Focus hunting at the long end of the zoom is fairly common.|
Continuous drive mode
The S10 has two continuous shooting modes; Continuous and Multi-shot 16.
The standard Continuous mode at best manages about 1.4 frames per second for about 3 or four shots, after which the speed drops and varies considerably, averaging around 0.9 frames per second. The camera occasionally refocuses when the shots are being written to the buffer, but you do appear to be able to shoot continuously (albeit at a reduced frame rate) until the card is full.
Multi-shot 16 combines 16 shots (at around 1.9 fps) into a single 6MP file as a 4x4 grid.
All-in-all the continuous shooting performance is nothing special, but is more than adequate for the kind of shooting the intended market is likely to need.
File writing / playback performance
The S10 is not particularly speedy when it comes to reading or writing to the card; a full 6MP / Fine image (2.2 MB) takes around 2.3 seconds to write to the card (~1.0 MB/s), and about a second to display in playback mode, but unless you're attempting to shoot long sequences you'll never notice (buffering takes care of that). The use of low resolution thumbs means scrolling through images is actually pretty fast; you only need to wait for the full image to load if you want to magnify or do anything else with the picture.
Battery life isn't bad at all; approx 300 shots (CIPA standard, VR on) per charge; though this drops drastically if you use the flash more often. The battery takes around 2 hours to charge from completely flat. The lack of an optical viewfinder means you are always using the LCD screen, so there's not really any way to increase battery life.
