Timing and Performance of canon eos 500d

Timing and Performance

Very good speeds for a consumer digital SLR.

Startup/Shutdown

Power on
to first shot
0.3 second

Time it takes to turn on and capture a shot. (Short enough that it's hard to measure.)

Shutdown
~0 second

How long it takes camera to turn off before you can remove the memory card. Enabling sensor cleaning on shut-down will increase delay.
Buffer clearing time
7 seconds
after 20 large/fine JPEGs*
Worst case buffer clearing time. -- This is the delay after a set of shots before you can remove the card.
1 second
after 20 small/normal JPEGs*
14.5 seconds
after 8 RAW files*
12.7 seconds
after 5 RAW+L/F JPEG files*
*Note: Buffer clearing times measured with a SanDisk Extreme 8GB SDHC card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance.
The Canon T1i turned in fast startup and shut-down times, fast enough that they're difficult to measure. Enabling sensor cleaning on shut-down will add some delay, but we didn't test that. The Canon T1i's buffer clearing times are quite good, but depend on the image quality and size, as well as the speed of the memory card.
