1Dmk4 obliterates D3s < ISO6400
Feb 7, 2010

Canon made compromises in pixel size for the benefit of having longer reach. And yet, most comparisons I've seen completely ignore this benefit by handicapping the 1D4. Inexplicably, almost all tests have either mounted a longer lens on the D3s, or moved the 1D4 backwards to reduce its reach. They've essentially defeated the very reasons for Canon's design compromises.

How do these cameras compare on a level playing field... same focal length for both? When the photographer is focal-length limited? After all, that's a very frequent situation for sports & wildlife shooters.

Fortunately, photographybay tested both cameras using the same focal length. I up-sized samples and compared the scene at the same size. The pixel density of the D3s is so low, that there are essentially 2 pixels in 1Dmk4 for every pixel in D3s. The D3s needed to upsize significantly just to catch up with the 1Dmk4, which explains the blurriness.

From low to moderately high ISO settings, the 1D4 utterly obliterates the D3s in image quality. The 1D4 maintains an advantage all the way up to ISO 3200. The D3s only pulls ahead at ISO 6400, with the margin widening at the über-extreme high ISOs. But the question is: How often do people really use images shot at über-extreme ISO settings? Is it more often than using images shot below ISO 6400, where the 1D IV clearly rules supreme?

The D3s would be an awesome camera for short or medium telephoto work. Anything longer... and its ridiculously low pixel density becomes more of a hindrance than an advantage.
