AF changes with AI Servo II
Stable lens drive: In normal operation, the AI Servo algorithm makes calculations, and based on these results, instructs the lens to change focus position. Now, if the algorithm gets two results one after the other that are very different - for example, the subject changed direction rapidly and was not where the system expected it to be - this calculation is ignored and the system waits to instruct the lens until two results match. This means that errors generated no longer cause the lens to jump unexpectedly out of focus. Secure focus tracking of a subject: If an obstacle is detected or if the AF point is not kept over the subject, tracking continues based on the last known trajectory result immediately before the interruption.
Moderate lens drive: If there is a radical change in focus distance, the lens is not driven straight to that value. It is slowly taken there based on past prediction results. This means that if a photographer drifts off the subject to the background for an extended period of time, the lens will not snap focus straight to the background. This in turn means that if the photographer gets the AF point back onto the subject that the lens is able to achieve sharp focus much more quickly.
Predictive control with quick response: The system is now able to achieve predictive focus immediately as the subject starts moving and there is no delay before it can start tracking.

London, 20 October 2009 – Canon today announces the launch of the new EOS-1D Mark IV – a high-speed, professional Digital SLR (DSLR) camera designed to empower photographers to capture split-second moments in high resolution, under the most challenging of conditions. Ideal for shooting action, sports, news events and wildlife photography, the Canon EOS-1D Mark IV delivers speed, power and high-resolution images, creating the perfect camera for photographers who require reliability in fast-paced, high-pressure situations.
Developed incorporating feedback from professional photographers, the EOS-1D Mark IV features a new Canon 16.1MP APS-H CMOS sensor and a brand new 45-point Auto Focus (AF) system with 39 f/2.8 sensitive cross-type points, providing a wide selection of precise focus areas across the frame. Dual “DIGIC 4” processors provide the power to shoot continuous, high-resolution images at up to 10 frames per second (fps), as well as delivering the widest ISO range ever to feature in a Canon camera.
“Throughout the EOS-1D Mark IV’s development, we’ve carefully studied feedback from our photographers and developed a camera to meet their specific requirements” said Mr. Shinbori, Senior General Manager of Camera Development Center, Canon Inc. “With a brand new, high-quality CMOS sensor and Dual “DIGIC 4” processors, the Canon EOS-1D Mark IV allows photographers to be the first to get the highest quality images to picture desks in what is becoming an increasingly competitive market.”
Highly sensitive, cross-type focusing – capture every detail at speed
The Canon EOS-1D Mark IV features a completely new 45-point AF system, with 39 f/2.8 sensitive cross-type points located across the frame, providing consistent AF on static or moving subjects, no matter which AF point is being used. All 45 AF points are user selectable and now more sensitive, with the AF points towards the edge of the frame offering identical levels of performance to those in the centre.
The entire AF system is managed by a dedicated microprocessor, providing fast, accurate focusing – even when shooting continuously at 10fps. Canon’s newly-evolved AI Servo II AF offers more precision when tracking moving objects, utilising the power provided by the dedicated microprocessor to improve overall tracking accuracy and increasing focus reliability in low-contrast and extremely bright conditions.
To provide increased flexibility, a vast range of manual and automatic AF control options are available including - with lenses featuring an AF Stop button - Canon’s new Spot AF feature. Spot AF offers a more precise focus area to meet the needs of photographers that require pinpoint focusing. A 63-zone metering system enables the use of multiple metering modes, with the dedicated sensor linked to the 45 AF points, providing AF point-linked and multiple spot metering options.
The EOS-1D Mark IV also features orientation-linked AF points, an orientation sensor controlled feature that enables photographers to store separate AF points for different camera positions. Covering both horizontal and vertical shooting positions (both grip up and grip down), orientation linked AF points offers the flexibility to quickly change camera orientation when shooting with the AF settings switching to suit the subject. AF point registration enables the photographer to store an alternate AF point that can be used at the touch of a button.
The power and performance of Dual “DIGIC 4” and CMOS
The combination of a custom-designed, high resolution 16.1MP APS-H CMOS sensor and Dual “DIGIC 4” processors ensures that detailed, crisp images are delivered at high speeds.
The inclusion of an APS-H sensor combines a high pixel-count with an effective field of view measuring 1.3x the focal length of the lens. This provides immediate benefits for sports, news and wildlife photojournalists, who operate on-the-move and need to get closer to their subjects and maintain fast apertures without resorting to longer focal-length lenses – which are typically heavier.
Continuous shooting is facilitated by the sensor’s eight-channel data read out, which provides a rapid read sequence and makes full use of the Dual “DIGIC 4” processors to enable high-speed 10fps shooting at full 16.1MP resolution, while maintaining image colours through 14-bit analogue to digital (A/D) conversion.
The ability to shoot images at 10fps, without any drop in resolution, means the EOS-1D Mark IV features the fastest continuous shooting with Auto Focus currently available from a Canon DSLR. The increased processing capacity of Dual “DIGIC 4” processors manages the increased data created by the 60% rise in image resolution, while still enabling the EOS-1D Mark IV to deliver a continuous burst of up to 121 large JPEGS, or 28 RAW images using a UDMA 6 card – ideal for fast-moving sporting action or news events where scenes are unfolding quickly.
The EOS-1D Mark IV also includes updated Picture Styles and the first ever integration of ALO (Auto Lighting Optimizer) in a professional EOS body, automatically correcting the contrast and brightness of images as they are recorded. These features combine to provide a faster workflow for those requiring press-ready images direct from the camera without the need for retouching, enabling photographers to concentrate solely on capturing that once-in-a-lifetime shot.
Full compatibility with the latest UDMA 6 standard Flash memory cards also ensures that image data is rapidly written to the EOS-1D Mark IV’s CF memory card. In addition, the flexibility to also record to a Secure Digital/SDHC memory card allows photographers to keep shooting for longer until they get the shot they need.
Advanced performance in low-light
The EOS-1D Mark IV also delivers extreme low-light performance. Standard ISO on the EOS-1D Mark IV ranges from 100-12,800, while extended ISO ranges from a low of 50 to 102,400 – the highest ISO ever offered by a Canon SLR. This extreme low-light performance makes the EOS-1D Mark IV ideal for night shots or shooting at evening events, where the lack of light would normally make shooting impossible.
Intelligent noise reduction techniques keep chroma and luminance noise to a minimum, while maintaining colour balance, but never take control of the overall image quality away from the photographer. The architecture of the new 16.1MP APS-H CMOS sensor, featuring gapless microlenses with less surrounding circuitry and more sensitive, high-capacity photodiodes, also ensures that all available light is used as efficiently as possible to maximise ISO performance in low light conditions.
Built for extreme use – robust, weatherproof and portable
Light for its category, the EOS-1D Mark IV features a full magnesium alloy body, providing protection against knocks and bumps. The EOS-1D Mark IV has also been the subject of some subtle ergonomic redesigns, with the buttons reshaped and given a more defined ‘click’ when pressed, to make life easier for photographers operating in more extreme weather conditions where gloves may be necessary.
The EOS-1D Mark IV is protected by a total of 76 rubber seals fitted around the controls and cover seams, making the Canon EOS-1D Mark IV dust and water resistant when used in tandem with Canon’s range of weather-resistant EF lenses and Speedlite EX flash units.
The 920,000 dot, VGA resolution, Clear View II LCD makes it easy to instantly review images and video in the most challenging conditions. By filling the gap between the LCD panel and the protective cover screen with a photo-elastic material, Canon has been able to reduce light reflection, resulting in the clear display of images. The previously acrylic cover has also been replaced by reinforced glass, providing strong, scratch-resistant protection for the screen.
The EOS-1D Mark IV also features the EOS integrated cleaning system, which automatically eliminates dust on the sensor – ensuring reliable image quality when shooting in testing outdoor environments.
Cinematic, High Definition video
In addition to providing high-quality still image performance, the Canon EOS-1D Mark IV features EOS Movie function, providing the ability to capture 1080p High Definition (HD) video at 30, 25 and 24fps and 720p footage at 60 and 50fps. As well as complete compatibility with PAL, NTSC and native 1080/24p cinematic frame rates, the EOS-1D Mark IV offers full manual exposure, providing film makers and photographers with control over depth of field.
The EOS-1D Mark IV features a programmable button to enable quick movie shooting, allowing photographers to record HD video instantly at the touch of a single button. The EOS-1D Mark IV also features a mini HDMI output, enabling video and images to be viewed directly on compatible HD-ready TVs.
Canon’s EOS-1D Mark IV is highly customisable, allowing photographers to take complete control of the camera’s features. Auto Exposure (AE) and Flash Exposure (FE) micro-adjustments allow photographers to fine tune the exposure for any given purpose, enabling them to perfectly match two separate cameras for consistent results or simply adjust the settings to meet specific personal requirements and tastes. Preferred user profiles can also be stored to memory card and subsequently transferred to other EOS-1D Mark IV bodies, so that photographers can seamlessly transfer their profile to another body if required.
Further customisable features include the ability to add copyright information directly in the camera. This enables photographers to embed their details within each shot as standard, removing the need for retrospective data insertion, and allowing news photographers to get shots to picture desks in the shortest time possible. An integrated microphone also allows the recording of audio notes to accompany each image, which will directly benefit photographers who wish to keep a record of the content of each image as they shoot.
Canon CMOS sensor
Designed by Canon and working in combination with the company’s DIGIC processors, Canon’s CMOS technology integrates advanced noise reduction circuitry at each pixel site delivering virtually noise-free images. In comparison with CCD technology, the lower power consumption characteristics of Canon’s CMOS sensors also contribute to longer battery life.
Signal conversion in Canon’s CMOS sensors is handled by individual amplifiers at each pixel site. Unnecessary charge transfer operations are avoided, vastly speeding up the process of getting signal to the image processor. Noise generation is reduced, power consumption is limited and faster frame rate potential is increased.
The architecture of the EOS-1D Mark IV sensor has been refined in order to derive maximum light efficiency and natural colour reproduction. Despite a smaller pixel size, optimised, more sensitive photodiodes, with higher signal to noise (S/N) ratios and larger capacities, allow more optical information to be gathered and transferred to the Dual DIGIC4 processors. This enables high ISO speeds, low noise, and a wide dynamic range to be achieved.
Additional features to reduce noise and support higher ISO speeds include: gapless microlenses, which have been moved closer to the photodiode to maximise the sensor’s light-gathering ability the circuit for applying high gain suppresses noise from outside the sensor itself
AI Servo II
AI Servo AF uses a form of Artificial Intelligence (AI) to determine the speed and direction of moving subjects, then focuses the camera lens to a predicted position (Focus Prediction Function) in order to increase the probability of obtaining a sharp photograph.
Realising the importance of AI Servo in today’s high speed cameras, the EOS-1D Mark IV autofocus system has been improved and is capable of accurately tracking a variety of subjects travelling at a variety of different speeds and distances. Tracking and focusing on macro subjects has been enabled through faster processing.
The following AF features have been improved with AI Servo II: Stable lens drive: In normal operation, the AI Servo algorithm makes calculations, and based on these results, instructs the lens to change focus position. Now, if the algorithm gets two results one after the other that are very different - for example, the subject changed direction rapidly and was not where the system expected it to be - this calculation is ignored and the system waits to instruct the lens until two results match. This means that errors generated no longer cause the lens to jump unexpectedly out of focus. Secure focus tracking of a subject: If an obstacle is detected or if the AF point is not kept over the subject, tracking continues based on the last known trajectory result immediately before the interruption. Moderate lens drive: If there is a radical change in focus distance, the lens is not driven straight to that value. It is slowly taken there based on past prediction results. This means that if a photographer drifts off the subject to the background for an extended period of time, the lens will not snap focus straight to the background. This in turn means that if the photographer gets the AF point back onto the subject that the lens is able to achieve sharp focus much more quickly. Predictive control with quick response: The system is now able to achieve predictive focus immediately as the subject starts moving and there is no delay before it can start tracking.
Dual DIGIC4 processors
Image information is processed by Canon’s Dual DIGIC4 processors, purpose-built to complement the 16.1 MP CMOS sensor. The power of Dual DIGIC4 enables more advanced processing algorithms to ensure precise, natural colours, accurate white balance and advanced noise reduction, as well as in-camera editing of EOS Movie clips filmed in full HD. The ultra-fast processing speeds raise the overall response rate of the camera operation and produce near-instant start-up times.
DIGIC chips work with a high speed DDR-SDRAM image buffer – reading, processing, compressing and writing image data fast enough to keep the buffer clear during long continuous shooting bursts. The buffer of the EOS-1D Mark IV’s Dual DIGIC4 processors has also been increased to support continuous bursts of up to 121 large JPEGs or 28 RAW files at 10fps, at full-resolution. In addition, as DIGIC 4 integrates all key processing functions, power consumption is kept to a minimum.
Working in tandem with Canon’s CMOS sensor, DIGIC 4 removes the highly-noticeable colour noise, as well as reducing luminance noise without loss in detail, allowing for very clean, high ISO images. Even at ISO 6400, noise levels are similar to those of ISO 1600 from DIGIC III. The Dual DIGIC4 processors also support M-RAW and S-RAW image formats, commonly used by news desks, to maintain the benefit of RAW files whilst reducing file size.
Clear View II LCD
EOS-1D Mark IV’s 3-inch LCD monitor has 920,000 dots (VGA resolution) with a viewing angle of 160°. Clear View II has been designed to combat glare by removing the air gap between the LCD’s protective cover and the liquid crystal display. The air gap is filled with a photo-elastic material. This suppresses the reflections from the surface of the liquid crystal, caused by the sharp change in refractive index as light travels through the air gap.
The EOS Movie function allows EOS-1D Mark IV users to record 1080p HD movies with full manual control and selectable frame rates.
Thanks to the large size of the integrated CMOS sensor (28.1x18.7mm), photographers have greater ability to control depth of field. The exposure of the movie can be controlled in Manual mode, allowing full control of shutter speeds and apertures. It is possible to select frame rates from: 30 (29.97), 25, and 24 (23.976), with 60 (59.94) and 50 available at resolutions of 720p. Program mode also allows photographers to easily shoot HD video without worrying about exposure settings– ideal when needing to capture split-second action as it unfolds.
Picture Style presets simplify in-camera control over image qualities. Picture Style presets can be likened to different film types – each one offering a different colour response. Within each selectable preset, photographers have control over sharpness, contrast, colour tone and saturation. The camera’s factory default configuration is set to deliver immediately-usable JPEG images without need for additional menu settings. Picture Style presets applied to a RAW image can be revised with Canon’s
The six presets are:
1. Standard – for crisp, vivid images that don’t require post-processing
2. Portrait – optimises colour tone and saturation and weakens sharpening to achieve attractive skin tones
3. Landscape – for punchier greens and blues with stronger sharpening to give a crisp edge to mountain, tree and building outlines
4. Neutral – ideal for post-processing
5. Faithful – adjusts colour to match the subject colour when shot under a colour temperature of 5200K
6. Monochrome – for black and white shooting with a range of filter effects (yellow, orange, red and green) and toning effects (sepia, blue, purple and green)
With the EOS-1D Mark IV, the Picture Style presets feature greater sharpening (for all presets excluding Faithful and Neutral), giving the photographer press-ready files straight from the camera.
Auto Lighting Optimizer
The Auto Lighting Optimizer (ALO) automatically corrects the image brightness and contrast for images suffering from underexposure, low contrast, or backlit situations, assisted by face detection technology. With DIGIC 4's low-noise image processing and corrective algorithm, the correction is performed without affecting the natural gradation. Standard, Low, Strong, or Disable settings can be set and applied to the image.
With the EOS-1D Mark IV, the Auto Lighting Optimizer now works with manual exposure and bulb shooting. The correction is based on the exposure set by the user and is especially effective for backlit conditions when the subject looks dark. Typically, if the exposure is brightened for the subject, the background becomes overexposed. However, with the Auto Lighting Optimizer set and the picture taken so that the background is not overexposed, both the subject and background can be favorably exposed.
EOS Integrated Cleaning System
The EOS Integrated Cleaning System combats sensor dust in three important ways: Reduce, Repel and Remove.
1. Reduce - Internal camera mechanisms are designed to minimise dust generation. The redesigned body cap prevents dust generation through wear on the cap itself
2. Repel - Anti-static technologies, including a special fluorine coating, are applied to the low-pass filter covering the front of the sensor so as not to attract dust
3. Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake dust from the infrared filter for a period of approximately one second after each start up. For instant shooting after power up, this feature is disabled immediately as the shutter release is depressed
Canon has also developed an internal Dust Delete Data system, which can map the position of visible dust on the sensor. This can then be deleted automatically after the shoot with the latest Digital Photo Professional software.
Digital Photo Professional Software
Digital Photo Professional software provides high speed, high quality processing of lossless RAW images. Processing with Digital Photo Professional allows real-time display and immediate application of image adjustments, giving control over RAW image variables such as white balance, dynamic range, exposure compensation, noise reduction and colour tone – plus the ability to view Auto Focus points on an image. The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. Images can be recorded in camera with sRGB or Adobe RGB colour space.
Digital Photo Professional supports sRGB, Adobe RGB, ColourMatch RGB, Apple RGB and Wide Gamut RGB colour spaces. ICC (International Colour Consortium) profiles can be attached to TIFF or JPEG images when converted from RAW. This allows faithful reproduction of colours in software applications that support ICC profiles, such as Adobe Photoshop. For improved efficiency, a set of image adjustments can be saved as a recipe and applied.
The latest version of EOS Utility provides essential support for Live View remote shooting, camera configuration and image transfers. Tightly integrated with Digital Photo Professional, EOS Utility can be configured to monitor ‘hot’ folders, automatically renaming and moving incoming images to a structured file system. Users can also tag their images with EXIF data, including copyright information.
Picture Style Editor
Picture Style Editor allows photographers to create individual Picture Styles that meet their personal requirements. Each Picture Style contains detailed information on how specific colours should be represented within an image. Once new Picture Styles have been created, they can be uploaded directly into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, both personal Picture Styles and predetermined Picture Styles can all be adjusted.

New 45-Point Autofocus System
The new EOS-1D Mark IV Digital SLR camera features Canon’s most advanced Autofocus system to date. It is equipped with a newly developed 45-point AF sensor featuring 39 high-precision cross-type AF points, and an all new AI Servo II AF mode that gives still photographers the power and performance to track and focus a fast-moving subject at speeds up to 10 frames per second. With more than twice as many cross-type focusing points as the EOS-1D Mark III and a new AF sensor construction that improves performance in low light and with low contrast subjects, the EOS-1D Mark IV has greater subject detection capabilities than any previous EOS model. To complete the range of AF improvements, Canon has developed a new AI Servo II AF predictive focusing algorithm that significantly improves responsiveness and stability by making better decisions on focus tracking in a variety of shooting conditions.
Amazing High ISO Performance
Wedding and event photographers shooting in low light without the benefit of a flash can take advantage of Canon’s widest ISO range and highest performance ever. The EOS-1D Mark IV camera’s ISO speed settings range from 100 up to 12,800 in 1/3 or 1/2 stop increments with ISO Expansion settings of L: 50 for bright light or H1: 25,600, H2: 51,200, and H3: 102,400 for even the most dimly lit situations. Photographers and documentary filmmakers working in available light will be impressed by the low-noise image quality of the 1D Mark IV, capturing amazing still images and video footage even at speed settings as high as ISO 12,800. High ISO, low light still images are further enhanced by Canon’s adjustable High ISO Noise Reduction feature, now a default setting in the camera.
The EOS-1D Mark IV, EOS HD Video Powerhouse
Over the past year, Canon’s EOS HD Video technology has changed the way users capture 1080p HD video and opened new doors for multimedia journalists and Hollywood cinematographers alike with full manual exposure control, selectable frame rates, and interchangeable lenses on some of the largest and most sensitive image sensors on the market. Canon continues this innovation trend with the new EOS-1D Mark IV Digital SLR with Full HD capture and full manual exposure control, plus selectable frame rates on an all-new APS-H-sized image sensor that’s similar in size to a Super 35mm motion picture film frame. The large sensor allows filmmakers to achieve shallow depth-of-field just as cinematographers have traditionally done using much higher-cost motion picture equipment.
The more than 50 Canon EF lenses compatible with the EOS-1D Mark IV give videographers incredible creative options, including an impressive selection of large-aperture professional L-series primes as well as zoom lenses, macro, Tilt-Shift and Fisheye optics. The Canon EOS-1D Mark IV allows for three video recording resolutions – 1080p Full HD and 720p HD in a 16:9 aspect ratio and Standard Definition (SD) in a 4:3 aspect ratio. The camera will record Full HD at 1920 x 1080 in selectable frame rates of 24p (23.976), 25p, or 30p (29.97); and 720p HD or SD video recording at either 50p or 60p (59.94). SD video can be recorded in either NTSC or PAL standards. Sound is recorded either through the internal monaural microphone or via optional external microphones connected to the stereo microphone input. The camera also provides an in-camera video editing function allowing users to remove the start or ending of a video clip directly in the camera to eliminate unwanted footage and speed up post-production.
Image Quality and Performance
The heart of the EOS-1D Mark IV camera’s outstanding image quality is a newly developed 16.1-Megapixel CMOS sensor featuring Canon’s latest and most advanced proprietary technologies. These technologies include improved photodiode construction to enhance dynamic range and gapless microlenses that are positioned closer to the photodiodes for improved light gathering efficiency. The transmissive quality of the colour filter array has been enhanced to improve sensitivity. Canon has also upgraded the sensor circuitry to improve noise reduction before the image data is exported from the CMOS sensor to the rest of the image processing chain.
With 60 percent more pixels than the EOS-1D Mark III, the EOS-1D Mark IV Digital SLR employs Dual DIGIC 4 Image Processors with approximately six times the processing power of DIGIC III for full 14-bit A/D conversion at 10 fps. High-speed continuous shooting up to 121 Large JPEGs is possible using a UDMA CF card. This camera also features three RAW shooting modes for versatility with Full RAW (approx. 16 million pixels), M-RAW (approx. nine million pixels), and S-RAW (approx. four million pixels). Three additional JPEG recording formats (M1, M2 and Small) are also available.
The 14-bit per channel conversion facilitated by the dual DIGIC 4 Processors provides smoother tonalities in final images capturing all 16,384 distinct tones in each channel (red, green and blue) at the full 10 fps frame rate. RAW images shot on the new Canon EOS-1D Mark IV use the entire 14-bit space when converted to 16-bit TIFF files in Canon Digital Photo Professional (DPP) software, which is supplied with the camera at no extra charge. The 14-bit A/D conversion is also the foundation for Canon’s Highlight Tone Priority feature that takes maximum advantage of the camera’s extensive dynamic range to preserve detail in highlight areas of the image. Canon’s new EOS-1D Mark IV Digital SLR also features an improved white balance algorithm making colours more accurate when shooting under low colour temperature light sources such as household tungsten lamps.
The EOS-1D Mark IV Digital SLR features Canon’s Peripheral Illumination Correction function which corrects darkening that can occur in the corners of images with most lenses when used at their largest apertures. When activated, it is automatically applied to JPEG images and video clips as they are shot. For RAW images, it can be applied in DPP software.
Other new features include a large three-inch solid structure Clear View II LCD screen with 920,000 dot/VGA resolution and a wide 160-degree viewing angle for enhanced clarity and more precise colour when reviewing images and shooting video. The new in-camera copyright information feature helps professionals secure control over images by setting copyright data directly into the camera and appending that information to each image file in the Exif metadata. Additional features include a fluorine coating on the Low Pass Filter to further repel dust and enhance the EOS Integrated Cleaning System.
Minimize Post-Production with Enhanced Canon Auto Lighting Optimizer
Action photography truly is all about speed, capturing a fast subject with fast focusing and fast frame rates. However, all this speed might be wasted if it is slowed down by lengthy post-production procedures to adjust image quality. The EOS-1D Mark IV Digital SLR helps reduce post-production work with a powerful new Auto Lighting Optimizer (ALO) system. When enabled, Canon’s ALO automatically adjusts the image for optimal brightness and contrast on the fly during in-camera image processing, reducing clipped highlights while keeping shadowed areas as clear and detailed as they actually appear. By optimizing brightness and contrast in-camera, Canon’s ALO system significantly reduces the need for post-production image optimization, and gives photographers image quality they can take directly to press. Demanding professional photographers who tested ALO clearly stated that this one feature will reduce their post-production image optimization process by more than 75 percent. Canon’s ALO works with both RAWi and JPEG images as well as video recording.
Canon has taken every measure to ensure that the EOS-1D Mark IV Digital SLR camera has the highest degree of weather resistance in the EOS line. The 1D Mark IV camera incorporates a wide range of design features that enhance its durability and reliability for professional assignments. For example, the 1D Mark IV’s body, chassis and lens mount are completely weather-resistant and 76 gaskets and seals surround all buttons and seams. The body covers and internal chassis, including the mirror box, are constructed with magnesium-alloy, one of the strongest and rigid metals available for its weight. For added strength, the lens mount is constructed with stainless steel. In fact, when used with Canon’s Speedlite 580EX II and/or most current L-series lenses, the entire camera system remains fully weather resistant, so professionals can concentrate on getting the shot instead of worrying about protecting their gear.
New Wireless Connectivity
Canon is announcing the availability of the new WFT-E2 II A* wireless file transmitter exclusively for the EOS-1D Mark IV Digital SLR camera. The WFT-E2 II A wireless transmitter is an extremely small and versatile device that offers professional photographers a wide range of digital connectivity options including IEEE802.11a/b/g and Ethernet, ideal for commercial and studio work. In addition to adding the ability to connect to wireless networks over 802.11a, the new WFT-E2 II A adds a wealth of new professional features to the photographer’s tool kit. The new Camera Linking feature allows a single photographer to simultaneously fire up to 10 cameras remotely; and the updated WFT Server mode lets you remotely use Live View, control settings, and fire the EOS-1D Mark IV over the internet from anywhere in the world using a standard Web browser or many Web-enabled smart phones. Additionally, geotagging is now possible via Bluetooth, using compatible GPS devices to append coordinate data to the images.
The Canon EOS-1D Mark IV Digital SLR camera is scheduled to be delivered to U.S. dealers in late December, and will be sold in a body-only configuration at an estimated retail price of $4,999.00ii. Final pricing and availability for the Canon WFT-E2 II A wireless file transmitter will be available later this year.

19th Waiting... :-)
One of our sources has said it's definitely 'IV' not 'V' - this via one of the people invited to Canon's world wide events to announce the camera.
Another vote for 1Dv [PB] also suggesting 1.3 crop but not much else of substance.
We hear (thanks) of a press conference tomorrow morning in Denmark and there's an ad at the top of this page that suggests a dealer will have a pre-production camera to look at by 13:30
Whilst waiting for new cameras, I've just finished a review of the rather useful DSLRRemotePro camera remote control software for several Canon EOS cameras. The new version now runs on Apple Macs too.
18th Are we to get a jump to the EOS 1DV?
17th Whatever may be announced in the coming week, many of our usual sources are saying they've not had any detailed info.
Have Canon finally manged to plug the leaks ;-)
14th Seems we had a few DNS problems overnight, but hopefully the site is visible again :-)
No one has recently said that the 1D4 won't be announced until February - indeed, we've now had several comments pointing to it matching the 102k ISO for the updated D3s
There's a copy of a Canon Australia 20th Oct invite at CR
As widely anticipated, Nikon updates the D3 to the D3s - specs
Key changes include
13th Another comment received about invitations going out for 'a new 1D' to be shown on Tuesday the 20th
