Sony has released Firmware v5.0 for the a9, which introduces Real-time AF tracking and Real-time Eye-AF, elevating the outstanding autofocus capabilities of this high-end camera.
The new autofocus system uses machine learning to identify objects and track them throughout the frame, relying on up to five separate characteristics to do so. Whether the subject turns away from the camera or is temporarily blocked by another object, the algorithm still maintains focus tracking. This machine-based learning also applies to Sony’s popular Eye-AF, improving the ability to capture and track focus on a subject’s eye. The new firmware also implements new focus selection tools and improved customization.
Image quality is also improved with the new firmware update, as it includes new internal processing to improve image quality in tonal gradations and more accurate auto white balance results, with less variation between shots in a single burst.
Version 6.0 is expected this summer, which will add Real-time tracking and Eye-AF for animals, as well as a built-in interval timer.
