• New AF system that demonstrates excellent response to moving subjects and tracking performance, even under a variety of circumstances: Pivotal moments happen in the blink of an eye, and photographers are constantly on their toes to capture the action regardless of the lighting conditions. These needs are addressed with a complete overhaul of the D5’s AF system with an adoption of the Multi-CAM 20K autofocus sensor module. The AF sensor module offers 153 focus points, 99 of which are cross-type sensors, for broad and dense coverage of the image area. The centre focus point has a detection range beginning at an incredible −4 EV, and detection with other focus points begins at −3 EV, enabling autofocusing even under extremely dim lighting, and with subjects exhibiting very low contrast. In addition, equipping the camera with a dedicated AF engine capable of high-speed calculation and collaboration with the 180K-pixel RGB sensor have ensured that extremely reliable AF performance is demonstrated with a variety of scenes.
