Strength PK SLR "real-time tracking" autofocus
SONY a9
Real-time tracking means that a9 (and a6400) can understand the subject you want to shoot algorithmically and track it in 3D, just like 3D tracking on Nikon digital SLR cameras and corresponding subject tracking mode cameras on various mirrorless cameras. Its performance makes the a9 system unique. It can be applied to various subjects-portraits, activities, snapshots, sports and even landscape photography, making it easier to use.
Sample appreciation
To select a target, you just need to recombine your autofocus point, put the autofocus point on the subject, and then press half the shutter. Real-time tracking collects information such as color, brightness, pattern, distance, face and eyes of the subject, and automatically tracks your subject in real time. If the face or eyes are detected on the object you are tracking, it will automatically switch directly to or from the eye autofocus. This means that you can focus on composition and moments. There is no need to draw more energy to keep the autofocus point on the main body. This inconvenience has limited the composition for many years, and it is helpless for unstable themes.
Appreciation of sports samples
This updated system can also handle dynamic images easily. Although many professional sports photographers can foresee a series of movements of athletes, they have been using single-point or regional AF for many years. Real-time tracking can help amateurs and professionals achieve better results. First of all, it allows photographers to compose freely, because composition is no longer influenced by free points that must be preserved. More importantly, when shooting a fast and unstable subject with a long-distance lens, it is more and more difficult to find the scene, so there is no need to keep a fixed focus or area on the fast-moving object in real-time tracking mode.
The improvement of real-time tracking makes it more convenient for us to shoot moving objects and more handy in free outdoor shooting. This makes A9 more powerful in its own good high-speed capture.
