Action photography is all about shooting subjects in motion, from pets at play to birds in flight, from athletic sports to ball games. As your subject is moving at speed it can be difficult to achieve the shot you're hoping for, but using the cameras and lenses best suited to capturing action will give you a great advantage.
In general, the most suitable cameras for action photography will have an advanced autofocus system with many AF points, helping you to accurately and continuously track subjects even when they're moving erratically. They should also have a fast maximum frame rate in Continuous shooting mode, with a sizeable memory buffer so you can capture a burst of more than just a few shots.
Ideal camera bodies for action include the Canon EOS R6 and the EOS R7. Both feature sensitive and intelligent AF based on deep-learning AI for tracking birds, animals, people and even vehicles, along with super-fast frame rates.
