Canon EOS-1D Mark III Performance
We'll have full results once we get a production unit into the lab for testing, but in the meantime, here's a few measurements we took with the pre-production unit.
NOTE: All performance numbers shown here are from a prototype camera: production models may show improved performance, please don't view the results shown here as final!
Timing and Performance
Excellent speed for a professional digital SLR.
| Startup/Shutdown |
||
| Power on to first shot |
~0.1 second |
Very fast, really limited by our own reaction times. |
| Shutdown |
~0 second |
Very fast, unmeasurable. |
| Buffer clearing
time |
38 seconds (22 RAW + LF JPEG shots*) |
Worst case buffer clearing time. -- This is the delay after a set of shots before you can remove the card. In the case of the Mark III, worst-case buffer clearing corresponded to 22 RAW + Large Fine JPEG shots using Continuous HI mode. |
| Mode

| Play to Record, first shot |
TBD second |

| Record to play |
TBD second |
Time to display a large/fine file immediately after capture. |
| Display recorded image |
TBD second |
Time to display
a large/fine file already on the memory card. |
| Shutter

| Full Autofocus |
0.069 second |
Time from fully pressing shutter button to image capture. (See note*** in paragraph below, camera alternated between 0.120 and 0.069 second in this test.) |
| Prefocused |
0.054 second |
Time
to capture, after half-pressing and holding shutter button. |
| Continuous
AF |
0.074 second |
This
mode usually shows no speed increase with our static subject; we have
no way to measure performance with moving subjects. |
| Manual
focus |
0.064 second |
For
most cameras, shutter lag is less in manual focus than autofocus,
but usually not as fast as when the camera is "prefocused". |
| Cycle

| Single Shot mode, Large Fine JPEG |
TBD |
Time per shot, averaged over buffer length. |
| Single Shot mode, 640x480 JPEG |
TBD |
Time per shot, averaged over buffer length. |
| Single Shot mode, RAW |
TBD |
Time per shot, averaged over buffer length. |
| 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. |

The Canon Mark III's performance was excellent overall, starting with a startup time that was really faster than our human reflexes. Full AF shutter lag was almost as fast as prefocused and manual focus lag times, which were also excellent. ***We did encounter an odd phenomena in checking full-AF lag times, namely that the time alternated seemingly at random between 0.069 second and 0.120 second. This variation was persistent across different lenses, and didn't correlate with any changes in either the scene or camera settings that we could detect. For what it's worth though, it did seem that pressing and holding down the shutter button produced the shorter times more consistently than did "punching" the button briefly.
Continuous HI mode speed was very impressive, but we noticed performance varied depending on the lens and especially the aperture used. Stopping down lenses to very small apertures slowed continuous-mode shooting, apparently because the lens aperture must return to its maximum setting between each shot for metering and/or focus determination. For best continuous speeds with the Mark III, use L-series lenses and shoot with the lens wide open. Again, keep in mind that this is a prototype, so these numbers may change once we test a full production unit.

The Canon EOS-1D Mark III uses a custom rechargeable LiIon battery for power, which is included with the camera, along with a charger.
Being an SLR, power consumption will depend a lot on what lens is being used, and how much the autofocus motor is used. Also keep in mind that the Mark III has no built-in flash, and that standard CIPA protocol tests with 50% of shots with flash enabled.
