I just purchased a Nikon D800 and dnld'd Lightroom 4.1. I am able to open my NEF files , and everything seems to work as well as it does with my D300 and D700 except the Camera Calibration tab. When I open it, there is no option for D800, and my only options are for Adobe St., and Camera landscape, neutral, portrait, standard, and vivid. There are not even options for all of these at v4 as there are with my D300 and D700. Is this a Bug or is my dnld bad. I have dnld'd v4.1 twice and nothing has improved.
