The Parallax effect is on full display in this panning shot of a Piper Cub landing at the 2025 Vintage Days Fly-in, Williamson, GA. You can tell which spot on the aircraft I used for the focusing target by looking for the sharpest area of the image. In this instance, the pilot. This was captured using my Nikon Z9 with the Nikkor Z100-400S @ 110mm, 1/15 sec, f/29, ISO 64.
