Autofocus
I was very impressed with the 49-point autofocus of the Fujifilm X-S1. It snapped into focus very quickly, especially for a camera that is essentially built upon the technology used in compact cameras. In continuous AF mode, the camera slowly sweeps into focus using the contrast AF system, although it can be overridden with a half-press of the shutter button to quickly snap into focus if the continuous AF is too slow.
The camera’s manual focus feature also works well, with a separate focusing ring sitting at the base of the zoom lens. Using the electronic viewfinder, it is clear to see when an image is in focus when using the manual focus control.
There is a slightly curious aspect to using manual focus that occurs when the shutter button is half depressed, which causes the manual focus ring to no longer work. In effect, the focus is locked until the shutter is released. This isn’t a big problem, but it is worth noting if, like me, you tend to have the shutter button half depressed when manually focusing in preparation for firing the shutter.
