A New Standard for Ultra-High-Quality Rapid-Fire Digital Image Capture Exceptional Performance Newly-developed 16.1 Megapixel CMOS Sensor When it comes to imaging sensor technology, Canon raises the standard for the industry with innovative in-house development and manufacturing advancements respected across the industry. The EOS-1D Mark IV features a new Canon CMOS sensor Canon APS-H (27.9 x 18.6mm) CMOS sensor. Actual size shown. with a capture resolution of 16.1 Megapixels (4912 x 3270), providing outstanding imaging detail. The recording area of the sensor is 27.9 x 18.6 mm (APS-H), yielding a lens conversion (crop) factor of approximately 1.3 in relation to traditional full-frame 35mm film. The latest Canon refinements in micro semiconductor manufacturing have further reduced sensor circuitry size. This leaves more physical space for the photodiodes, enabling their collective area to be significantly increased. The larger sensor photodiode area results in wide dynamic range, elevating imaging performance to a level never before achieved with such high pixel site density. The new photodiode design also improves photoelectric conversion rate, providing a markedly improved S/N ratio. The resulting boost in sensitivity makes higher usable ISO speeds possible. A new fabrication process eliminates gaps between the microlenses, yielding even higher light gathering efficiency. The new CMOS sensor thus delivers a remarkable combination of high resolution, low noise and unprecedented high ISO shooting capability. 59 Dual DIGIC 4 Image Processors Developed by Canon, DIGIC Image Processors are found exclusively in Canon digital cameras. The EOS-1D Mark IV incorporates not one, but two DIGIC 4 Image Processors operating in tandem to further boost performance, ensuring natural color reproduction and handling the data from the new highresolution sensor at high speeds for instantaneous camera response. This remarkable parallel processing power makes possible not only high-speed shooting, but also such advanced features as Full HD video recording with comprehensive frame rate options, Live View with Face Detection AF, HDMI output, UDMA Mode 6 (CF card) support and advanced Auto Lighting Optimizer. Unprecedented ISO Range Combining the inherent low-noise performance of the new imaging sensor and the sophisticated noise reduction capabilities of the Dual DIGIC 4 Image Processors, Canon engineers have endowed the EOS-1D Mark IV with the widest ISO range yet in an EOS digital SLR: 100-12800 in standard Pixel size [µm square] 5.7 50 L ISO speed range 100 - 12800 H1 H2 H3 102400 mode, settable in 1/3-stop increments. In extended range modes, the photographer can select a low ISO speed of 50 and one of three high settings: 25600 (H1), 51200 (H2), 102400 (H3). This greatly expanded capability provides a previously unavailable range of real-world shooting options, especially in available-light or dim situations. Also significant is the camera's improved low ISO range performance. The new Canon CMOS sensor features advancements that make it possible to operate with reduced electrical charge saturation. This improves imaging performance at the low end of the ISO scale, which can be highly useful when shooting high contrast scenes with fast (e.g., f/1.4) lenses. Blown highlights can be avoided, and photographers can use wider apertures to control depth-of-field in ways not possible at higher ISO settings. The EOS-1D Mark IV now also provides an ISO Auto option. When this feature is selected, the camera automatically selects ISO within the standard range of 100-12800 to provide the best exposure for the shutter speed and aperture combination selected by the photographer. Sophisticated Noise Reduction The advanced algorithms developed for the powerful Dual DIGIC 4 Image Processors significantly improve noise control capability. They more effectively remove not only color noise but also luminance noise. This results in dramatic subjective image quality enhancement because, while color noise is more readily noticed, luminance noise affects factors such as perceived image "naturalness." At extremely high ISO settings, the EOS-1D Mark IV clearly reproduces fine detail and subtle gradations. Moreover, all noise reduction settings other than the highest (Strong) can now be used without affecting the camera's continuous shooting speed. 10.0 fps High-speed Continuous Shooting The new CMOS sensor in the EOS-1D Mark IV features an improved, faster single-line reading sequence and an 8-channel signal path that achieve remarkable data transfer speeds. The camera drive system has also been enhanced with a two-motor design and an active mirror bounce suppression mechanism. These and other advances in the shutter assembly, autofocus system and Dual DIGIC 4 Image Processors make possible highspeed continuous shooting at 10.0 fps at full 16.1 Megapixel resolution. Maximum bursts EOS-1D Mark IV features an improved AI Servo AF focus tracking and 10.0 fps high-speed continuous shooting, for sharp, detailed photographs in every shot. TECHNOLOGY during continuous shooting are 121 shots for JPEG Large (at a compression setting of 8) and 28 shots for RAW. When shooting RAW+JPEG (at compression 8), the maximum burst is 20 shots. 14-bit A/D Conversion The EOS-1D Mark IV is equipped with a 14-bit A/D converter which means that tonal gradations for RAW images are now represented by 16,384 separate levels per channel rather than 4,096 of 12-bit. When saved as a 16-bit TIFF image, the image retains the full range of tones captured at 14 bits. Moreover, 8-bit-per-channel JPEG images are generated from the 14-bit data. Artifacts related to limited dynamic range, such as tonal skipping and highlight clipping, are thereby substantially reduced. The 45-point Area AF sensor features 39 cross-type highprecision AF points with manual AF point selection. Any of the 45-points are selectable. New High-Precision AF System Improved 45-point AF Sensor The EOS-1D Mark IV incorporates an amazingly precise, newly-developed 45-point Area AF sensor. Compared to the 19 points in the previous Mark III, 39 of the focusing points are crosstype (provided manual AF point selection is used), and any of the 45 points can be selected manually if desired. When the maximum lens aperture is f/2.8 or faster, the new AF system executes highly accurate cross-type focusing with f/2.8-equivalent light flux vertical line detection and f/5.6-equivalent light flux horizontal-line detection. The center AF point is a cross-type sensor providing f/4-equivalent light flux vertical-line detection and f/8 horizontal-line detection. When the maximum lens aperture is f/4 or faster, the center AF point provides high-precision cross-type focusing. When the maximum lens aperture is f/8 or faster (including the use of an extender), the center AF point uses horizontal-line detection. Many popular Canon EF Series lenses, including several with f/4 maximum aperture, can take advantage of 39 cross-type focusing point precision with this new system. More Accurate Focus in More Situations Both One-Shot AF and AI Servo AF modes are provided to cover a wide variety of shooting situations. The AI Servo AF mode has been reengineered to ensure improved speed and stability with more reliable focus-tracking performance. The new algorithms make it possible to more accurately track subjects that move irregularly. In addition, AI Servo AF greatly enhances macro photography with algorithms that automatically sense the use of a macro-focusing lens at close distances, appropriately adjusting AF operating parameters to better accommodate unpredictable camera/subject movement. Powerful, Customizable AF Operation The photographer can select any one of the 45 AF points manually or allow the camera to make the selection automatically. To select an AF point manually, the user can press the AF point selection button, then use either the Multicontroller or a combination of the Main and Quick Control Dials to highlight the desired point in the viewfinder. As with previous EOS-1 series cameras, the photographer can use a Custom Function to automatically expand a manually selected AF point. The expansion of points can be limited by the user to 19, 11, inner 9, or outer 9. A Custom Function can also AF Point Expansion Selections 45-point 19-point 11-point Inner 9-point Outer 9-point AF Point Expansion With single AF point selected With two AF With right AF points selected point selected C.Fn III-8-1 C.Fn III-8-2 With C.Fn III-8-3 AI Servo AF AF point manually selected Points for AF expansion AF Point Registration Automatic AF point switching to registered AF point when camera's orientation is changed. be used to pre-register an AF point for selection on demand. Another Custom Function enables the user to enable or disable the burst of short flashes when a flash unit without an IR AFassist beam is used. Brilliant 100% High-magnification Viewfinder The viewfinder on the EOS-1D Mark IV delivers exactly what professional photographers want: a large, bright image that provides clear, accurate framing, focus and shooting parameter information. Most digital SLR viewfinders display less than 100 percent of the actual capture area, which makes it difficult, if not impossible, to accurately frame an image. The EOS-1D Mark IV viewfinder not only provides approximately 100% coverage, but also does so with a high magnification of 0.76. The 28.3-degree angle of view is also uncommonly wide. The viewfinder has a high eyepoint of 20mm and provides built-in dioptric adjustment in the range of -3 to +1. Photographers can also choose from a range of optional interchangeable focusing screens to suit specific needs. 60
