I just got a new camera and decided to make a noise comparison with the old one, they are very close, so would like a second opinion.

To get an unbiased opinion, I am not going to tell you what models it is (don't worry it is 2 Nikon cameras), so that way it is a "blind test".

First, some test background and then (next post) some pictures.

Since noise at a certain ISO is not always the same, but incises as the shutter time goes up, as well as light quality goes down (WB corrections will increase noise in the other colour channels), this test is done with just one fluorescent lamp.

Both cameras had a custom WB, and was manually focused using live-view.
All pictures was taken with the camera on a tripod and mirror-up.

The raw files was processed into jpgs with Aftershot Pro (formerly known as Bibble). Then crops was made.

The shutter speed ranges from 2.5 sec @ iso 200 to 1/13 sec @ iso 6400, so this is a fairly cruel test.

First is a down-sampled picture of the scenery with daylight WB, so give you an idea of the setup.
