Our Noise analysis contains a database of Noise measurements we have made in our lab. The readings below are the average of standard division values taken from the 6 gray patches in the Gretagmacbeth 24 patch chart. You can read more about our lab noise tests here.
Please choose one or more cameras to compare noise standard division statistics.
Noise as function of ISO
Noise as function of luminance

Notes
Canon EOS-1D Mark III NR OFF: The Canon EOS-1D Mark III also has an High ISO Speed Noise Reduction mode which you can find at the drop-down menu at the top.
Canon EOS-1D Mark III NR ON: High ISO Speed Noise Reduction is set to ON
Review
Canon EOS-1D Mark III NR OFF: The default NR off setting of the Canon EOS 1D Mark III is very much the same as it was with DIGIC II, luma and chroma noise are reduced together. The result has quite a lot of chroma noise when compared to other DSLR cameras out there. Compared to other DIGIC II based cameras, the EOS 1D Mark III does show lower noise levels (which could mean higher filtering levels of course). However, when setting C. FnII-2 Noise Reduction to ON, the results are a whole different story. You can select Canon EOS-1D Mark III NR ON to view the results.
Canon EOS-1D Mark III NR ON: The Canon EOS-1D Mark III is the first DSLR to use the new DIGIC III, which now joins the rest of the Japanese industry to use the new age Chroma noise reduction. This means that when C. FnII-2 is set to ON, the EOS Mark III will reduces Chroma noise (color noise) almost completely. In fact, in some zones the std. levels drops to 0. Canon does in fact reduce luma noise in some cases more than when C. FnII-2 is set to OFF, so C. FnII-2 is not entirely affecting Chroma noise alone, as some might think. Once again, we see that Luma noise at ZONE 6 has almost as much noise as in ZONE 5. It is interesting to note that apparently canon has chosen not to reduce chroma noise aggressively in ISO6400. This might suggest that DIGIC III is straggling to find edges in high levels of noise, so canon had to find a good balance. Overall, very impressive. Although this database can’t show this, the actual RAW noise levels from the EOS 1D Mark III sensor are very good.

Nice Job! Thanks.
