With the recently released, free firmware update in version 3.00, Fujifilm primarily addresses the AF performance of its flagship APS-C camera Fujifilm X-H2S. According to Fujifilm, two AF functions in particular have been improved: First, subject/object detection and second, dynamic tracking performance - both via improved AI algorithms.
Here is the very detailed promotional video for the 3.0 firmware update of the Fuilm X-H2S:
In terms of subject/object detection, two areas in particular are said to have been improved : Firstly, difficult subject situations such as backlighting, sideways viewing and small lenses are now said to be better detected by the AF system. Secondly, new subject categories have been added. Face", "Eyes", "Animal", "Bird", "Automobile", Motorcycle & Bike", "Airplane" and "Train" have now been joined by "Insect" and "Drone".
Better motion prediction is said to have been added to the dynamic tracking performance of the AF. According to Fujifilm, this makes it possible to track fast-moving subjects more reliably.
In addition, the dynamic tracking performance is said to have improved the response time of the Fujifilm X-H2S when starting continuous shooting, when the subject is still out of focus and is to be quickly focused for the first time via AF-On button.
The improved AF functions should also be explicitly noticeable in video mode.
In our extensive field tests with the Fujifilm X-H2S and the Fujifilm X-H2, we had already liked the AF performance quite a bit - however, we had wished for the option to freely define an AF tracking point, as currently offered by Sony, Canon and Panasonic. In our eyes, this is a very practical feature, especially for gimbal shots - because you don&t always want to track one of the predefined subjects, but rather a picture detail, for example. Whether this AF function has also been implemented with the new firmware update remains to be seen.
