Canon EOS 6D Sensor Less Noisy Than EOS 5D Mark III

Interesting test made by Don Marcotte, a photographer with interests in astrophotography. He wanted to know which camera sensor among the EOS 6D and the EOS 5D Mark III produces less noise. The test was made with a rather simple setting: long exposures wit the cap on the lens (no light). Before looking at the results it is best to read Marcotte's disclaimer:

Please remember that this test was designed to determine the best camera for a very specific night photography project. I would expect that no one could detect a noise difference between the 6D and 5D3 for the vast majority of daylight photography. Only in low light conditions would a 6D deliver observably better results.

Ok, the EOS 6D produces less noise than the EOS 5D Mark III. Check the following images:

It is amazing that Canon's entry level full-frame DSLR produces less noise than the much more pricey EOS 5D Mark III!
