I use Litchi in waypoint mode to survey wildlife reserves. Typically I create a mission that will have the camera taking 50-100 images looking straight down with each image overlapping the adjacent one. I use Litchi because I can plan the mission and edit it using CSV's. The DJI GS Pro does not provide the editing flexibility I need. What I am seeing is a variation in the focus when using AFC with some images being out of focus. I am also seeing a variation in focus when in Auto mode and tapping the screen to focus, sometimes the focus is spot on other times it is not. I am wondering if the variation in focus is an issue with all X4s cameras or just my one. The X5s with the 15mm DJI lens is fine with focus spot on every time, the issue with this camera/lens is the reduced field of view and the reduced flight time.
