Canon PowerShot SD870 IS Performance


Timing and Performance

Good to average speed for a consumer camera.

Startup/Shutdown

Power on
to first shot

1.0 second

Time it takes for LCD to turn on and lens to deploy.

Shutdown

1.2 seconds

How long it takes to retract lens and stow in your pocket.

Buffer clearing time

1.0 second
(large/superfine JPEG)

Worst case buffer clearing time. This is the delay after a set of shots before you can remove the card. Some cameras won't retract their lenses and shut down until the buffer is cleared.

Mode switching

Play to Record,
first shot

1.1 seconds

Time until first shot is captured.

Record to play

1.1 seconds

Time to display a large/superfine file immediately after capture.

Display
recorded image

1.0 second

Time to display a large/superfine file already on the memory card.

Shutter response (Lag Time)

Full Autofocus Wide

0.38 second

Time from fully pressing shutter button to image capture, zoom lens at wide angle position.

Full Autofocus Tele

0.42 second

Time from fully pressing shutter button to image capture, zoom lens at telephoto position.

Prefocused

0.088 second

Time to capture, after half-pressing and holding shutter button.

Cycle time (shot to shot)
Single Shot mode
Large SuperFine JPEG
2.18 seconds

Time per shot, averaged over 20 shots.

Single Shot mode
640x480 Normal JPEG

2.07 seconds

Time per shot, averaged over 20 shots.

Early shutter
penalty?

No

Some cameras refuse to snap another shot if you release and press the shutter too quickly in Single Shot mode, making "No" the preferred answer

Continuous mode
Large SuperFine JPEG

0.76 second (1.32 frames per second);
No limit w/fast card*;
1.0 second to clear

Time per shot, averaged over buffer length or 20 shots, whichever came first. Slows to 1.47 seconds or 0.68 fps above ISO 200.

Continuous mode
640x480 Normal JPEG

0.77 second (1.30 frames per second);
No limit w/fast card*;
0.5 second to clear

Time per shot, averaged over buffer length or 20 shots, whichever came first. Slows to 1.47 seconds or 0.68 fps above ISO 200.

Flash recycling

8 seconds

Flash at maximum output.

Download speed

Windows Computer, USB 2.0

1,053 KBytes/sec

Typical Values:
Less than 600=USB 1.1;
600-769=USB 2.0 Low;
Above 770=USB 2.0 High

*Note: Buffer clearing times measured with a Kingston Ultimate 133x SD memory card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode.

The Canon PowerShot SD870 IS's performance here is pretty good overall. Start-up time is quite fast at about one second. Shutter lag at wide angle and telephoto zoom is very good, at 0.38 and 0.42 second respectively, and "prefocus" times (half-pressing and holding down the shutter button before the final exposure) are very fast, with a shutter delay of only 0.088 second. Shot-to-shot cycle times are on the slower side of average these days, at about 2.2 seconds for large/superfine JPEGs. The SD870's continuous shooting speed of 1.3 frames per second is only average for its class these days, however it captures frames continuously at this rate. Flash recycle time is a bit below average, at 8 seconds after a full-power shot. Connected to a computer, download speeds are reasonably fast, so you won't feel a need for a separate card reader. Bottom line, the Canon SD870 IS is a good camera for average shooting conditions, though you'll need something a little zippier for sporting events or active children.

Battery and Storage Capacity

Battery
Slightly above average battery life for a lithium-ion design.

Operating Mode Number of Shots
Lithium-ion rechargeable battery
(CIPA standard)
270

The Canon PowerShot SD870 IS uses a custom rechargeable lithium-ion battery for power, and a battery and charger are included with the camera. Though runtimes are above average, I strongly recommend picking up a spare battery and keeping it freshly charged and on-hand for extended outings.

The table above shows the number of shots the camera is capable of (on a fully-charged rechargeable battery), based on CIPA battery-life and/or manufacturer standard test conditions.

Storage
The PowerShot SD870 IS accepts SD/SDHC/MMC memory cards, and comes with a 32MB starter card.

We strongly recommend buying a large capacity SD/SDHC memory card for the Canon SD870 at least a 1GB card, preferably a 4GB one, to give yourself extra space for extended outings or movies. (Check the shopping link above, cards are really cheap these days, so no reason to skimp.)
