I’ve toyed with the title of this article. Technically, this isn’t about eye-AF, it’s about a simplification of Fujifilm’s autofocus. The reason for this is I don’t think eye-AF is the complete solution to user problems, at least not entirely. It’s a great feature, and Sony’s facial preference technology (which gives preference to specific people) is the kind of technology that is helpful for some scenarios, but the real reason for the – popularity of eye-AF is the ability of the AF to decide the appropriate starting point for autofocus. In essence it’s the simplification of the AF system, and by simplification, I mean dumb it down to get better results without losing performance.
The current Fujifilm AF system is great but it requires constant customisation to get the best out of it, and most users don’t know how to do it, nor do they want to. You could argue that cameras are technical pieces of equipment, but in the land of iPads and Google, technical devices are becoming increasingly simple. For that reason, AF needs to be incredibly powerful and simple at the same time like ABS, traction control and similar technologies that are both powerful and simple.
