User manual CANON EOS 1D MARK IV BROCHURE

[. . . ] Technology Features New AF system & Wide ISO Speed Range The EOS-1D Mark IV, heritage and innovation combined The EOS-1D Series, launched in 2001, combined exceptional image quality and superb handling. Canon's goal was to empower photographers to be able to confidently capture decisive moments even in the most challenging shooting conditions. Since its inception, the EOS-1D Series has evolved in performance and functionality without Canon ever wavering from its vision. Every improvement further enhanced the ability of these cameras to capture the decisive moments. [. . . ] The new AI Servo AF ignores data input if autofocus calculations are suspect, delivering consistent predictive control through the use of more accurate calculations involving prior subject movement. Dynamic predictive capability 100 [m] Shooting distance Custom Functions make it easy to set autofocus to handle special shooting situations. Canon determined the default camera settings based on accommodating the largest number of photographers in the most common shooting situations. But because each photographer has a unique shooting style or sometimes must deal with situations outside the norm, Canon included C. Fn III: AF/Drive. When developing the EOS-1D Mark IV, Canon recognized the need for new AF-related Custom Functions in response to the camera's improved functionality. Fully understanding the new settings will assure photographers get the most out of the EOS-1D Mark IV for the ultimate shooting experience. Camera rotated C.

Fn III-6-7 To improve subject-tracking performance, the lengths of line sensors extend outside the visible AF point. Spot AF shortens the active area of each line sensor to more closely correspond to the AF point shown in the visible point. This function, which can be enabled with the AF stop button found on super-telephoto lenses, is ideal for situations when the default focus area covered by the AF point is too large, such as when trying to maintain focus on a race car driver's eyes instead of the helmet. Using Spot AF, the focus area covered by the AF area is reduced to roughly half the default size. When active, the AF point blinks brighter than normal. Notes: · Autofocus may take longer when the subject is out of focus. · For optimal results when using this function, it is essential to keep the subject inside the AF point or AF performance will be reduced. · Spot AF is only available when using EF lenses that are equipped with an AF stop button. 4 5 AI Servo AF tracking method Lens drive when AF impossible 12 AF point auto selection 13 14 15 16 17 AF point display during focus AF point brightness AF-assist beam firing Orientation linked AF point Mirror lockup 6 Lens AF stop button function 20 10 8 7 AF Microadjustment Spot AF 8 AF expansion with selected point 18 Continuous shooting speed 9 Normal AF point focus area Spot AF point focus area Multi-controller while meter : New or improved functions 1 5 10 50 100 500 Speed of subject (km/h) 19 Limit continuous shot count High-speed continuous shooting Register Low-speed continuous shooting Apply Disable Enable Number limited Register Apply 10 to 2 fps (per shot) 1 to 9 fps (per shot) 99 to 2 fps (per shot) 7 8 ISO SO Technology Control over digital and semiconductor technologies gives birth to the widest ISO range in EOS history. The benefits of high ISO-support extend to low ISO speeds. Images shot at low ISO speeds can exhibit noise in shadow areas, even if brightened using tone curve adjustments. However, if an image has low noise to begin with, tone curve adjustment can be used more effectively and confidently. Leveraging low-noise capability at both ends of the ISO scale allows Canon to equip the EOS-1D Mark IV with a variety of image-enhancing functions, such as Peripheral Illumination Correction and Auto Lighting Optimizer. The former adjusts image quality based on the unique optical properties of a lens, while the latter balances images for optimal brightness and contrast to produce photos that closely resemble what the human eye sees. These functions, enabled by default in the EOS-1D Mark IV, ensure improved image quality at all ISO speeds. A first for EOS: Standard ISO range from 100 to 12800 for enhanced versatility. A wide ISO range gives photographer's added versatility when setting exposure. The standard sensitivity range of the EOS-1D Mark IV covers ISO 100 to 12800, a full seven stops. (In comparison, the EOS-1D Mark III has a five-stop range, from ISO 100 to 3200). This is the widest ISO range of any EOS Digital camera, offering an unprecedented level of control over exposure without having to rely on flash. [. . . ] In the EOS-1D Mark IV, noise reduction is set to Standard by default, with Low, Strong, and Off settings available. * The maximum continuous shooting speed decreases when using the Strong setting. The history of the EOS-1 series has seen a succession of Canon technological firsts. With the Controlling the ISO range helps photographers adjust to changing scenes. There may be times when unusually bright conditions preclude the need for a high ISO setting even when fast shutter speeds are required, or when optical image quality is more desirable than the action-stopping capability provided by a high ISO. In situations such as these, photographers can use Custom Function C. Fn I-3 to narrow the default ISO range. [. . . ]
