Timing & Performance

Although the menus feel a little quicker than the DP1, the DP2 isn't any quicker in use - the focus is still slow and most actions have enough of a delay to make the camera feel unresponsive. Some users will feel that this dawdling will encourage them to contemplate each shot before they take it but you can get the same effect with a fast camera and a little self discipline, whereas no amount of positive thinking can make the DP2 quicker.

Timing Notes

All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2640 x 1760 Fine JPEG image (approx. 2,700 KB per image). The media used for these tests was a 8GB Sandisk Extreme III 30MB/s Edition SDHC 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 tables below show 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. The media used for these tests was a 4GB Sandisk Extreme III 30MB/s Edition SDHC Card. Shutter speed was kept above 1/200 sec during these tests.

The DP2 can shoot short burst of images at a pretty reasonable 3.3 seconds but, unlike most other contemporary cameras, will not then attempt to keep shooting at a reduced rate: when you've filled the buffer the camera locks up for a little under ten seconds. Once the rear screen starts showing a live preview again, you can shoot another burst.

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 the activity indicator went out. This means the timings also include the camera's processing time and as such are more representative of the actual time to "complete the task". The media used for these tests was a 8GB Sandisk Extreme III 30MB/s Edition SDHC Card.

Even with a fast card these write times are very slow by modern standards.

Battery life

The DP2 uses the same BP-31 battery as the DP1 and it yields just 250 shots. Its few enough shots that most people should consider buying a spare - it's not a bad number compared to most modern compacts but it'll come as a huge shock to those photographers who are used to large-batteried, shoot-all-day DSLRs.
