Eye-controlled focus, also known as Eye Control AF, is a focusing system in cameras that allows the user to select the focus point by simply looking at the desired subject within the camera's viewfinder.
How Eye Control AF Works
This technology utilizes advanced sensors and infrared LEDs built into the camera's viewfinder to track the user's gaze. Here's a breakdown:
- Infrared LEDs: The camera emits infrared light into the eye.
- Sensors: Sensors within the viewfinder detect the reflections of this infrared light off the eye.
- Gaze Tracking: By analyzing the patterns of these reflections, the camera determines where the user is looking within the frame.
- Focus Point Adjustment: The camera then automatically adjusts the focus point to coincide with the area the user is looking at. This allows photographers to quickly and intuitively shift the focus without manually selecting focus points.
Benefits of Eye Controlled Focus
Eye-controlled focus provides several advantages for photographers:
- Speed: Enables faster focus point selection compared to manual selection methods.
- Intuitive Control: Offers a natural and intuitive way to control focus.
- Improved Composition: Allows photographers to concentrate on composition without being distracted by focus adjustments.
Example of Use
Imagine photographing a group of people. With Eye Control AF, you can shift the focus from one person to another simply by looking at them through the viewfinder. The camera automatically adjusts the focus to the person you're looking at.
