The FUJIFILM X100F features the X-Trans CMOS III sensor specifically designed for the X Series. The X-Trans CMOS III uses an aperiodic color filter array to eliminate the need for an optical low-pass filter. The 24.3MP APS-C sensor controls noise beautifully despite its increased pixel count, allowing the standard sensitivity range to be boosted to ISO12800, which was in the extended sensitivity range in previous models. Additionally, the phase detection area has been expanded to enable phase detection AF, allowing the camera to function with greater speed and accuracy than ever before.
