Fujifilm’s new continuous autofocus settings explained
Two of Fujifilm’s latest cameras – the X-T2 and the X-T20 now use an improved algorithm for continuous autofocus to boost the accuracy of subject tracking. Five presets are available for both cameras, with the X-T2 allowing you a sixth option – a custom preset of your own choosing.
Every preset has a set of three sliders – Tracking sensitivity, Speed tracking sensitivity, and Zone area switching – so here’s what each one means:
Tracking sensitivity – This setting affects how closely the camera follows your initial subject, letting you tell the camera how long to wait for a subject to reappear. This ranges from 0 to 4, and setting 0 makes the camera switch focus immediately, while settings from 1 to 4 increase the amount of time it waits.
Speed tracking sensitivity – This setting tells the camera how often your subject is changing speed. This ranges from 0 to 2. 0 means the camera expects your subject to be moving at the same speed throughout, while 2 means the camera will be expecting multiple changes of speed and adjust to compensate.
Zone area switching – This is only available in Zone AF mode, and lets you specify which part of the frame the camera should focus on. There are only three options here: Center, Auto and Front. As you might guess, Center keeps focus on the center of the frame all the time, while Front switches focus to whichever subject is at the front of the frame when the original subject moves out of it. Auto simply tracks the initial subject.
