I am a relative newbie. I want to make movies of aircraft with my Nikon 5600. I suspect, that because the aircraft are on the runway, taking off, or already in the air, that they are all essentially “at infinity”. Thus my guess would be to not use auto focus, but just manually focus once for a sharp image, and then just leave it there. Any suggestions ?
In addition to back button focusing and AF-C, learn about depth of field and hyper focal distance. Depending on the lens used and it’s focal length, setting an f stop of f8 or f11 and setting focus at some midpoint distance, you may not need to focus each image after you have set focus at the hyper focal distance.
