I just want to confirm for those that might be interested ...... on the NIKON D3200, the "Auto Distortion Control" function, when set to "ON" in the camera, DOES indeed correct/affect the NEF/raw file output. It is picked up by ViewNX 2 and shown in the meta data there. Oddly, there is apparently no option there to toggle it off or on. So, once selected in the camera, it is set, at least in ViewNX 2.
Additionally, when "Auto Distortion Control" is set to "ON" in the camera, it reduces the multi-shot buffer from 8 down to 7 when set to RAW only.
