I have had some difficulty trying to source these. Basically will correct the small amount lens distortion created by the Phantom 3. If you are running the latest versions of this software you are fine as these lens profiles are automatically included. However if you are like me and running an older version of Lightroom you will need to add them manually. Windows: Add the DJI folder form the zip to you main drive (E.g. C drive) then Program Files - Adobe - Adobe Lightroom - Resources - LensProfiles - 1.0. You will see other brands of cameras here. E.g. Apple, Canon etc Mac: See j3yps post below. Download the folder from https://www.dropbox.com/s/2rvkdh29nyu105x/DJI.zip?dl=0 I believe the P3 Pro is the FC300X and the P3 Adv is the FC300S.
