Timing & Performance

Although the C875 isn't up with the fastest cameras available, overall performance is perfectly acceptable for a budget camera, and rarely really gets in the way of day to day picture taking. The telephoto focus is a bit sluggish (never been one of Kodak's strong points), but unless you're taking action shots it's not a massive issue. If you do want to capture the action at the long end of the lens I'd advise pre-focusing (or digging a bit deeper and buying a faster camera!).

Timing Notes

All times calculated as an average of three operations. Unless otherwise stated all timings were made on an 8MB JPEG image (approx. 1,6700 KB per image). The media used for these tests was a 1.0 GB Sandisk Extreme III card.

Shot to Shot Flash on ( red eye reduction on / off) 1.5 / 2.1 *1
*1 Shot to shot times are pretty fast but as the C875 will take a picture without focus being locked you have to be careful. Flash shot to shot times are higher at greater distances and when the battery is low.

Continuous drive mode

The C875 has a single standard burst mode that we measured at almost exactly 2.0 frames per second. You can shoot up to 5 frames in a single burst, after which there is a delay of around 25 seconds before you can take another full burst (whilst the images are written to the card), though you can take another single shot after around 8 seconds. A second 'last burst' option takes pictures at 2.0 fps for up to 15 seconds, saving the last 4 frames when the shutter button is released.

File writing / playback performance

As with most Kodak models the C875 is a bit sluggish when it comes to writing the card (it takes around 5.3 seconds to save an 8MP file (around 1.6MB), a pedestrian 0.3 MB /s), though the relatively efficient buffering means you'll rarely notice. Playback performance is much better, with 8MP images taking no more than 0.2 seconds to display. Incidentally we noticed during testing that the C875 - like many Kodak cameras - uses much stronger than average JPEG compression, producing 8MP files as small as 700KB. There's no control over the compression.

Battery life

The C875 offers various options for power, but most users will opt for NiMH rechargeables, which give somewhere around 200-300 shots per charge (CIPA standard) - not bad at all. We found the C875 to be one of those cameras that's very fussy about which batteries you use and we had real problems with non-rechargeables (alkaline batteries are reported as dead within minutes of putting fresh ones in). Stick to good, 2100mAh or higher NiMH cells for the best performance.
