I have been using the 1DX for about 4 months now. The majority of my images are from a set up in my yard but I have noticed this issue in other locations as well. I shoot manual mode and AWB 95% of the time and I do RAW conversions with ACR. What I have noticed is that when I open an image in ACR almost all the time the color is slanted fairly heavily toward magenta. Usually in the range of +10 to +15. I have to adjust it on almost every image to avoid a magenta color cast. It occurs with both my 300mm f/2.8L and my 500mm f/4L lenses. Is this a normal tendency for the camera or is it pilot error?
