When shooting with focus mode set to AF-A, sometimes the camera does not maintain focus on a moving subject.
Shooting moving subject with focus mode set to AF-A
In AF-A mode, the camera automatically recognizes whether the subject is moving or not, and switches the AF mode between AF-S and AF-C accordingly.
When shooting fast-moving subjects with focus mode set to AF-A, sometimes the AF mode cannot switch fast enough and the camera may not continue to focus on the moving subject.
In such cases, we recommend setting the focus mode to AF-C.
