Canon Achieves its Best DxOMark Overall Score with the 5D Mark III

April 19, 2012 – DxOMark, the Internet website of reference for measuring digital camera image quality, has just published the results of its analysis of the new Canon EOS 5D Mark III, which obtained the best DxOMark Overall Score for all Canon-brand full-frame digital cameras.

With a DxOMark Score of 81 points, the Canon EOS 5D Mark III edges out the Canon 1Ds Mark III (80 points) by one point and gains two points on its predecessor, the Canon EOS 5D Mark II (79 points), putting it in 10th place overall (for all cameras) in the DxOMark rankings.

Progress of DxOMark Scores for full-frame Canon sensors since 2002

“Canon achieves its best Score with its new 22-megapixel sensor, although the difference is very slight with respect to the former number one sensor, the Canon 1Ds Mark III,” observed Frédéric Guichard, DxO Labs’ Scientific Director. “Even though Canon achieves the same performance as Nikon in terms of sensitivity, Canon is still behind its competitor in terms of dynamic range, Nikon apparently having taken advantage of the latest sensor enhancements that improve the handling of dark noise.”

The Canon EOS 5D Mark III provides very good performance in low light, putting it in 5th place overall for this category. Canon had announced that its sensor would show improved sensitivity thanks to a new gapless micro lens array that would capture more light, and at nearly ½ stop better than the 5D Mark II, its performance meets our expectations.

The Canon EOS 5D Mark III’s sensor dynamic range is similar to that of the 1Ds Mark III, putting Canon’s last-born in 49th place for this category. This means that the manufacturer has made very little progress since the appearance of the 1Ds Mark III and the 1D Mark IV, the best-rated Canon cameras in this category.

About DxOMark

Sponsored by DxO Labs, DxOMark is the web most reliable, objective, manufacturer-independent source of image quality related information that demanding photographers can trust for cameras and lenses. Going far beyond the usual scope of camera and lens reviews, DxOMark offers the following exclusive benefits:

For photographers who shoot in RAW, DxOMark is the only image quality information resource that gives them what they really need: measurement of straight-from-camera RAW files. DxOMark rankings and analyses are never affected by in-camera image processing. As a result, DxOMark is the only available way to evaluate camera RAW performance.

It’s a little-known scientific fact that the image quality of a lens is strongly dependent on the camera on which it is mounted. DxOMark is the only resource that measures the performance of each lens with every compatible camera – resulting in a wide range of different results for the same lens! For a photographer assessing a lens for his or her own camera, this is the only information that counts.

No two manufacturers measure ISO sensitivity, exposure time, focal length and other key parameters in the same way. Consequently, manufacturer-published image quality data cannot be compared. Only DxOMark takes its own measurements for all camera and lens settings and parameters that influence image quality – without ever relying on the manufacturers’ published specifications – and then normalizes the test results so that the performance of different cameras and lenses can be compared in a valid and meaningful way.

To ensure precision and reliability, all measurements are performed at DxO Labs’ dedicated testing laboratories, where conditions and protocols are controlled using standardized metrology. These protocols are detailed on the DxOMark website, so that anyone interested in performing their own measurements can do so.

DxOMark measurements rely on DxO Analyzer, the world’s leading turnkey laboratory solution for image quality evaluation. Thanks to its accuracy, completeness, and reliability, DxO Analyzer has become the definitive reference tool for numerous leading imaging industry players, photography magazines, and websites.
