The Canon EOS 1D Mark III shows remarkable high ISO performance in the above samples. I am satisfy with photos taken with ISO 2000 and ISO 3200. The subject was not properly lit. The details of the subject are remained, this can be seem on the subjects hair. Skin tone on the ISO 3200 photo is a little bit washed out but looks good on the one taken using ISO 2000.
Let me know what you think about the sample photos at the comment section.
