Having had the Canon 5D mark 2 for over a week I decided it was time to put it through its paces and test the high ISO performance and noise levels showing. I was fortunate to be having a shoot with new model Bekki and took a number of shots in sequence ramping up the ISO between them.
The results show that noise is very controlled up to ISO 6400 but beyond that the images would only be suitable for emergency use. As a sign of both the quality of the full frame sensor in the 5D mark II and the improvement in camera design I looked at the images from my first digital camera, the Nikon Coolpix 775 back in 2002. The noise levels at ISO 100 are higher than those at ISO 6400 from the Canon 5D II.
