The Autofocus that is the camera does will be inconsistent in its results if there is motion or low contrast objects where it is looking when it does it. You can redo the autofocus at any time during the flight or you can use the manual focus value to lock it in to a known good value.

If some are crisp and others are blurry this may be because the distance between the camera and the objects is changing. The autofocus solution is only valid at one distance. That is how focus works.
