EOS-1D Mark IV Features & Highlights From the Manufacturer New 45-point Area AF sensor including 39 cross-type AF pointsThe EOS-1D Mark IV has a newly developed, high-precision Area AF sensor with 45 manually selectable points including 39 cross-type, high-precision AF points for exacting and fast focusing no matter the subject. New AI Servo II AF focus tracking features improved algorithms that help improve stability, reliability and focus no matter the situation. Whether shooting a fast paced soccer game or shooting a close-up of a bee on a wind-blown flower during macro photography, AI Servo II AF helps ensure sharp focus every time. AF point selection has been improved as well. Photographers can select their own point through either the camera's Multi-controller or Main Dial/Quick Control Dial. Automatic selection is as simple as the press of a button. With Custom functions, photographers can select their own default focus point to automatically switch between horizontal and vertical shooting and can even choose to have primary focus supported by adjacent focus points for more accuracy with moving subjects. 10.0 fps continuous shooting up to 121 Large/JPEGS or 28 RAW using a UDMA CF card

The EOS-1D Mark IV's spectacular new 45-point high speed AF sensor locks on and maintains focus, ensuring that the camera keeps up with its amazing shutter.

All the EOS-1D Mark IV's controls, buttons and external covers are dust- and water-resistant, ensuring uninterrupted operation whether shooting in the rain, in a windstorm and everything in between. Dust is managed with the advanced Canon EOS Integrated Cleaning System, which helps to suppress dust generation, removes existing dust and uses the combination of Dust Delete Data and DPP software to eliminate any remaining dust spots on your images. When the EOS-1D Mark IV is used with a dust- and water-resistant EF lens or external Speedlite, the entire camera system is nearly impervious to the elements.
