So I purchased a D610 on the 23rd of December. The plan was to buy the atomos ninja star and some rokinon cine lenses when funds would allow. After playing with it I noticed that the camera had some odd compression with lower iso's in underexposed areas altough I have been able to see the issue up to 400 iso. I then compared it to my D3200, Hacked GH1, and Unhacked GH1. All three produced better results than the D610. I decided it must be defective and took it back to the store I bought it from they said that wasn't right and exchanged the cameras. My new D610 has the same odd 'color stepping' although a lot less than the first one. Also my D3200 still seems to perform better at low light with the same settings. The second one also has dead/stuck sensor pixels. I have been trying to deal with Nikon but with limited success. The two options I was given was to pay to ship my brand new camera to them for repair, or to return it to the store I bought it from. Anyone else ever have this weird issue that I am guessing is related to the sensor. Here are some links to the video.
