Z9 is the newly developed FX-format 45.7MP BSI stacked CMOS sensor. Its stacked design offers fast readout speeds and helps to reduce rolling shutter, and the BSI design contributes to impressive clarity and minimal noise when working at higher sensitivities 45.7MP, it's also a high-resolution chip that benefits landscape, portraiture, and other detail-oriented genres, as well as enables recording video at resolutions up to 8K. The full-frame BSI design is known for exquisite color and detail rendering 493-point phase-detection AF system to realize fast and accurate focusing performance. This system is benefitted by the high-speed communication of the Z interface along with the speed of the sensor that enables AF readings to occur at up to 120 fps.
