2. Focus Modes
The Sony A6100 offers several focus modes to cater to different shooting needs. Here’s an in-depth look at each mode:
2.1 Single Autofocus (AF-S)
Purpose: AF-S, or Single Autofocus, is designed for photographing stationary subjects. It locks focus when the shutter button is pressed halfway and maintains that focus until the shutter is fully pressed or the camera is turned off.
How It Works:
- Focus Lock: Once the camera acquires focus on the subject, it locks the focus, which is particularly useful for still subjects.
- Use Case: Ideal for portraits, landscapes, and any scenario where the subject is not moving.
Tips for AF-S:
- Ensure Proper Focus: Before taking the shot, ensure that the focus is locked on the desired area. Use the camera’s focus indicators to verify focus accuracy.
- Use with Tripod: For added stability, especially in low light, using AF-S with a tripod can prevent camera shake and maintain focus.
2.2 Continuous Autofocus (AF-C)
Purpose: AF-C, or Continuous Autofocus, is designed for moving subjects. The camera continually adjusts focus as the subject moves, ensuring that it remains in sharp focus throughout the shot.
How It Works:
- Continuous Adjustment: The camera continuously updates the focus to track moving subjects.
- Use Case: Perfect for sports, wildlife, and any dynamic scene where subjects are in motion.
Tips for AF-C:
- Use Continuous Shooting Mode: Combine AF-C with continuous shooting to capture multiple frames and increase the chances of getting a sharp image.
