  • AF Speed and Tracking Sensitivity: Fine-tune these parameters to match your subject’s movement.

Techniques for Maintaining Focus During Shooting

Implementing proper techniques helps ensure focus remains accurate throughout your shot:

  • Pre-Focus: Focus on your subject before starting recording to lock in sharpness.
  • Use Focus Lock: Lock focus on a static subject to prevent shifts during movement.
  • Monitor Focus: Continuously check focus using the camera’s LCD or external monitor.
  • Adjust Focus Manually: Switch to manual focus if autofocus struggles in complex scenes.

Additional Tips for Focus Accuracy

Beyond settings and techniques, consider these additional tips:
