Canon Introduces the EOS-1D Mark IV

Canon introduces the next evolution in the EOS-1D series of cameras: the Canon EOS-1D Mark IV Digital SLR camera. The EOS-1D Mark IV camera is a high-speed multimedia performance monster with a 16-megapixel Canon CMOS sensor, Dual DIGIC 4 Imaging Processors, and 14-bit A/D data conversion, all at 10 frames-per-second (fps), with the widest ISO range Canon has produced to date. This new camera also features 1080p Full High-Definition video capabilities at selectable frame rates packaged in a rugged and durable professional camera body.




------------------------------ Official Press Release ------------------------------
New 45-Point Autofocus System
The new EOS-1D model 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. 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
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.

The EOS HD Video Powerhouse
Over the past year, Canon's EOS HD Video technology has changed the way users capture 1080p HD video and provides them with full manual exposure control, selectable frame rates, and interchangeable lenses on some of the largest and most sensitive image sensors on the market. The large camera sensor allows filmmakers to achieve shallow depth-of-field just as cinematographers have traditionally done using much higher-cost motion picture equipment. 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.

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. The transmissive quality of the color 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. 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 colors more accurate when shooting under low color temperature light sources such as household tungsten lamps.

Auto Lighting Optimizer
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.

Rugged Reliability
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.

Pricing and Availability
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 $4,999.00.
