I want to use a 5DM3 and a 100-400 to shoot both photos and videos of kids doing gymnastics from a distance. The kids will be still in one spot and then run and do somersaults.
1.Is it better to use manual or auto focus for this?
2. If I choose manual focus, I can zoom in and focus on the subject before they start moving to achieve sharp focus, though once they start running, how do you ensure the focus is maintained?
Thanks.
