In this video I demonstrate that "Tap to Focus" is not new for DJI drones. There's been a lot of talk about the new DJI Mavic Pro drone as a lot of the early video from it was very soft and out of focus. Later on people realized that the video was soft and out of focus because it WAS out of focus and needed to be focused.
I guess the earlier Phantom series drones had fixed focus and didn't need to be manually focused, but since at least the Inspire 1 Pro drone, that's been around for about a year, tap to focus has been a standard aspect of camera operation on the Inspire 1 Pro/RAW drones.
So, I demonstrate both the tap to focus and color grading of a flat D-Log video file. The footage at the beginning is both out of focus and not color graded but about the 0:32 mark I tap to focus and at 0:44 I also bring in the color grading to the flat D-Log video. The conditions were pretty tough given the time of day was almost noon and with a landscape with little color or contrast the scene as viewed with my eyes was pretty flat and was further compressed with D-Log.
