Last week I updated the firmware on my D7100 and just ran through some images since the update. The info on the update said that it addressed linear noise issues in video taken with the camera. I was hoping that it might also help with linear noise in still images. I'm happy to report that after the update, linear noise, or "banding" has been greatly reduced in still images. I recommend that anyone that has this body and tends to push their shadows in PP, update as soon as you can, it finally gives the camera the low light recovery I was looking for when I purchased this body.
