It can definitely be challenging to take photographs while also following the action in a live sports game. One way that professional photographers overcome this challenge is by pre-planning their shots and anticipating where the action is likely to happen on the field. This can help them be ready to capture the key moments of the game. It can also be helpful to have a telephoto lens, which allows you to zoom in on the action from a distance, so you can get close-up shots without being right on the field. Finally, it's important to be familiar with your camera's settings and to be able to adjust them quickly, so you can get the best possible shots in different lighting conditions and action scenarios.
