Full Lab Test: Canon EOS 1D Mark III

Canon traded megapixels for speed with this model. The Nikon D2Xs, another camera in the pro class, captures 12.4 megapixels on a 1.5x crop factor sensor at full resolution at 5 fps, and drops resolution to 6.8 megapixels (and a 2x crop factor) for a high-speed burst of up to 35 JPEGs at 8 fps. The Mark III's full-frame stablemates, the 12.8 megapixel Canon EOS 5D and the 16.6MP Canon EOS 1Ds Mark II, capture images at a more leisurely pace: 3 fps for 60 JPEGs and 4 fps for 32 JPEGs, respectively.

Performance
As our testing analyst Matthew Fitzgerald quipped, the Canon 1D Mark III is "a rocket ship." The camera took 0.1 second to start up and capture its first JPEG, then took 0.4 second between shots when capturing subsequent JPEGs. When shooting raw, the camera took 0.5 second between shots. Shutter lag measured 0.4 second in our high-contrast test, which mimics bright shooting conditions, and 1.1 seconds in our low-contrast test, replicating dim shooting conditions. Our lab tests were performed with Canon's EF 50mm f/1.2L USM lens.

Image Quality
Images shot with the Canon EOS 1D Mark III can be absolutely stunning. Colors look extremely accurate, and the automatic white balance does an excellent job of neutralizing colors under a variety of lighting situations. The only times it became confused was in situations in which there was mixed lighting, and even then it produced pleasing, if not absolutely spot-on results. If paired with a sharp lens, the 1D Mark III can produce images with a vast amount of fine detail.

However, where this camera really shines is its ultralow noise. Even at its highest sensitivity setting of ISO 6,400, we were able to make pleasing prints. On a monitor you'll see a covering of fine, multicolored grain, but there's still an impressive amount of shadow detail and finer detail, especially for such an extreme setting. At lower sensitivities, images are extremely clean, and noise doesn't even begin to show up significantly on monitors until you reach ISO 800

An analysis of EOS-1D Mark III autofocus performance

In our April 22, 2007 first look at the Canon EOS-1D Mark III, we described the camera’sautofocus as being blazingly fast at acquiring initial focus. So fast that covering women’s volleyball over several days was pure joy, thanks to an incredibly responsive autofocus system in the preproduction body on loan from Canon. We also found its autofocus to be quicker off the line in dim light than
any camera we’d used before.

In our April 22, 2007 first look at the Canon EOS-1D Mark III, we described the camera’s autofocus as being blazingly fast at acquiring initial focus. So fast that covering women’s volleyball over several days was pure joy, thanks to an incredibly responsive autofocus system in the preproduction body on loan from Canon. We also found its autofocus to be quicker off the line in dim light than any camera we’d used before.

But that wasn’t the end of the autofocus story. We went on to say:

  • Q. Is the autofocus better in the production EOS-1D Mark III than it was in the preproduction unit?
  • Q. What are the camera’s autofocus problems?
  • Q. You say the camera’s autofocus difficulties occur or are worse “under certain conditions” – what does that mean?
  • Q. You described the EOS-1D Mark III as being incredibly fast at acquiring focus initially, but you also describe the camera’s ability to focus initially as being a problem. Can you explain the contradiction?
  • Q. Doesn’t the EOS-1D Mark III have a feature that allows you to adjust the autofocus so that the camera doesn’t shoot out of focus pictures?
  • Q. How does the EOS-1D Mark III’s autofocus compare to the EOS-1D Mark II N?
  • Q. Will Canon fix the problems? Can Canon fix the problems?
  • Q. Should I return my EOS-1D Mark III or keep it while I wait for Canon to fix the autofocus?
  • Q. I’d like to test my own EOS-1D Mark III. Any suggestions?
