The Canon EOS-1D Mark IV features a newly developed 16.1-megapixel APS-H size (27.9 x 18.6 mm) CMOS sensor and Dual DIGIC 4, comprising two high-performance DIGIC 4 image processors, making possible an expanded normal ISO sensitivity* range of 10012,800 for beautiful image quality with low noise at all settings. The camera also allows an extended ISO range of 50102,400. Low-sensitivity settings support outstanding results for outdoor portrait-photo shoots under bright lighting conditions or when using large strobe lights in a studio environment, while high-sensitivity settings boost performance when shooting indoor sports action and night games or conducting nighttime photojournalism. The camera makes possible a continuous shooting speed of up to approximately 10 frames per second for up to approximately 121 large JPEG images in a single burst.
The EOS-1D Mark IVs newly developed 45-point AF (autofocus) sensor, including 39 cross-type AF points with sensitivity up to f/2.8, ensures greatly improved focusing accuracy. Equipped with AI Servo AF II, incorporating a new algorithm, the camera achieves high levels of AF stability and tracking performance.
