Autofocus Techniques
Most DSLR cameras feature continuous focusing, also known as AI Servo. This mode
will allow you to track moving subjects. Keep your center focusing point over the
aircraft with your shutter held halfway down. As you follow the plane through your
viewfinder, the camera will automatically adjust the focus as the aircraft gets closer.
When you are ready to make an image, simply press the shutter all the way down. Air
Show organizers often arrange photo passes where the pilot flies at a reduced speed.
Don’t get too comfortable though, they return to full speed after just a few slow turns.
