Luminous Landscape D3x, 5DII and A900 Noise Comparison
Dec 28, 2008

"I see no significant noise difference between the Nikon D3x, Canon 5D MKII and Sony A900 up to and including ISO 800.

At ISO 1600 and higher the Sony falls behind the Canon and Nikon by about 1 EV. It's simply a noisier camera at high ISO.

From ISO 1600 to ISO 6400 the Canon 5D MKII and the Nikon D3x are neck and neck. I think that the visible differences on-screen at I00% are a quibble, and on prints are completely irrelevant.

The Canon then goes the equivalent of two stops higher. But I see both ISO 12,500 and 25,600 on the Canon as being marginally usable at best, and then only for emergency documentation. My feeling is that they were added for marketing rather than for real world shooting purposes."
