Canon PowerShot TX1 Performance
Timing and Performance
Good to average speed for a consumer camera.
Startup/Shutdown |
||
Power on |
1.9 seconds | Time it takes for LCD to turn on and lens to deploy. |
Shutdown |
2.3 seconds | How long it takes to retract lens. |
Buffer clearing time |
1 seconds (buffer clearing after LSF 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. |

3.3 seconds | Time until first shot is captured |
Record to play |
1.3 seconds | Time to display a large/superfine file immediately after capture |
Display |
1.3 seconds | Time to display a large/superfine file already on the memory card. |
Shutter response (Lag Time): | ||
Full Autofocus Wide |
0.62 second | Time from fully pressing shutter button to image capture, zoom lens at wide angle position. |
Full Autofocus Tele |
0.38 second | Time from fully pressing shutter button to image capture, zoom lens at telephoto position. |
Prefocused |
0.070 second | Time to capture, after half-pressing and holding shutter button. |
Continuous AF |
0.81 second
|
This mode usually shows no speed increase with our static subject; we have no way to measure performance with moving subjects.

Cycle time (shot to shot) | ||
Single Shot mode
Large SuperFine JPEG |
1.68 seconds | Time per shot, averaged over 20 shots. |
Single Shot mode |
1.56 seconds | Time per shot, averaged over 20 shots. |
Early shutter |
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 |
0.99 second (1.01 frames per second); 1 second to clear |
Time per shot, averaged over 20 shots. |
Continuous mode |
0.98 second (1.02 frames per second); 1 second to clear |
Time per shot, averaged over 20 shots. |
Flash recycling |
7.2 seconds | Flash at maximum output. |

*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 TX1's performance ranges from good to just average, though its 7-second flash recycle time is a bit slow. Start-up time is reasonable, but not fast. Shutter lag at wide angle and telephoto zoom settings is good, and "prefocus" times (half-pressing and holding down the shutter button before the final exposure) are fast as well, with a shutter delay of only 0.070 second. Shot-to-shot cycle times are a little longer than average these days, at about 1.7 seconds for large/superfine JPEGs, but the camera captures frames continuously at this rate. Continuous-mode speed is on the slower side, at about one frame/second, though again the camera captures frames continuously. Connected to a computer, download speeds are exceptionally fast, so you won't feel a need for a separate card reader. Bottom line, the Canon TX1 is responsive enough for most family photo opportunities, though its continuous shooting mode might be a tad slow for kids or sporting events.
Battery and Storage Capacity
Battery
Short battery life for a lithium-ion design.
Operating Mode | Number of Shots |

The Canon PowerShot TX1 uses a custom rechargeable lithium-ion battery for power, and a charger is included. Runtimes are well below average, so we strongly recommend you pick up an extra battery pack and keep it charged and on-hand for extended outings.
The table above shows the number of shots the camera is capable of (on either a fresh set of disposable batteries or a fully-charged rechargeable battery as appropriate), based on CIPA battery-life and/or manufacturer standard test conditions.

Storage
The Canon PowerShot TX1 accepts SDHC/SD/MMC memory cards, and a 32MB card is included with the camera.

We strongly recommend buying a large capacity SDHC/SD memory card at least a 2GB card, preferably a 4 to 8GB one, especially if you'll be shooting video. An 8GB card will record 62 minutes at highest quality 640x480 30fps. Set resolution to 16:9 1280 at 30fps, and that drops to 28 minutes.
