Somewhat slow performance overall, though with some average timings.

Startup/Shutdown
Power on to first shot	2.0 seconds	Time it takes for LCD to turn on and lens to deploy and capture a picture.
Shutdown	2.4 seconds	How long it takes to retract lens.
Buffer clearing time	0.5 second after 20 L/F JPEGs	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.

Slow startup and shutdown times, though a consideration here is the PowerShot SX200 IS' long 12x lens. Buffer clearing time is faster than average.

 

Shutter Response (Lag Time)
Full Autofocus Wide	0.46 second	Time from fully pressing shutter button to image capture, zoom lens at wide angle position.
Full Autofocus Tele	0.40 second	Time from fully pressing shutter button to image capture, zoom lens at telephoto position.
Prefocused	0.076 second	Time to capture, after half-pressing and holding shutter button.

Shutter response is good at both wide angle and telephoto, at 0.46s and 0.40s respectively. "Prefocusing" the camera by half-pressing and holding down the shutter button before the final exposure results in a lag time of 0.076 second, which is fair.

 

Cycle Time (shot to shot)
Single Shot mode Large Fine JPEG	2.57 seconds	Time per shot, averaged over 20 shots.
Early shutter penalty?	No	Some cameras don't snap another shot if you release and press the shutter too quickly in Single Shot mode, making "No" the preferred answer.
Continuous mode Large Fine JPEG	1.04 seconds (0.97 frames per second) >20 frames 0.5 second to clear	Time per shot, averaged over buffer length or 20 shots, whichever came first.
Flash recycling	3.5 seconds	Flash at maximum output.
*Note: Buffer clearing times measured with a SanDisk Extreme III SD memory card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity also affects cycle times and burst mode performance, with higher ISOs generally increasing cycle times and reducing burst performance.

Shot-to-shot cycle times are sluggish, at about 2.57 seconds for large/fine JPEGs, though the camera appears to capture frames continuously at this rate. Cycle times are also slower than average in Continuous mode, at about 0.97 frames per second. The flash takes about 3.5 seconds to recycle, which is better than average.

Overall, the Canon PowerShot SX200 IS is a bit slow. Clearly not designed for action photography, the PowerShot SX200 IS should still handle most average photography situations well, with about average shutter lag times. However, you'll be waiting a little between shots at full resolution, so consumers needing a faster cycle time should bear that in mind.

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

Operating Mode	Capacity
Lithium-ion Rechargeable Battery, Still Image Capture (Based on CIPA standard)	280 shots
Lithium-ion Rechargeable Battery, Playback Time	300 minutes

The Canon PowerShot SX200 IS uses a custom rechargeable lithium-ion battery for power, and ships with a charger. Although battery life is pretty good, we recommend you pick up a spare battery and keep it freshly charged and on-hand for extended outings, especially if you plan to shoot a lot of video.

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

Storage
The Canon PowerShot SX200 IS accepts SDHC/SD/MMC/MMCplus/HC MMCplus memory cards, but does not ship with a card.

We strongly recommend buying a large capacity SDHC memory card. (These days, 4GB is a good tradeoff between cost and capacity.) You'll want a fairly fast one (at least a Class 4) for HD movie capture.
