The 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.
Powerful ISO Sensitivity
The EOS-1D Mark IV features a standard ISO range from 100 - 12800 with an expanded range of 50 to 102400. The combined noise reduction capabilities of the Dual DIGIC 4 Image Processors and the Canon CMOS sensor help ensure that even at an ISO setting of 102400 noise is kept to a minimum. This greatly expanded capability provides an increased range of real-world shooting options, especially in available-light or dim situations. A low ISO speed can be useful, for example, when shooting high contrast scenes at large apertures. Blown highlights, such as the shading of a bride's dress, can be avoided and photographers can use wider apertures to control depth-of-field in ways not possible at higher ISO settings. Additionally, the EOS-1D Mark IV features the Auto Lighting Optimizer (ALO), which automatically adjusts the brightness and contrast during image processing to minimize the need for expensive and time-consuming post-production processing. Auto Lighting Optimizer is available in most shooting modes, including Manual mode and can be applied to RAW images using the included Canon Digital Photo Professional software.
