3. Shooting Objects in Action
Shooting objects in fast action such as race cars or bicycles can be frustrating when you use auto focus. Your autofocus will be faster if you have a fast lens but this cannot always compete with fast action shots.
To get the right focus, you can switch to manual focusing and pre focus on a point that the subject will move through and shoot exactly at that point. For this to work, you will need to get your timing right.
