Well now … A lot of rumors were running on the web in recent days, the Canon EOS 1D Mark IV is now officially announced ….

As Canon 7D, 5D MKII, the 1D Mark IV embeds a video mode 1080/24/30p and 720/60p …. Which we hope will be more bloody than the 7D … In short, Canon announces 16.1Mpix sensor AF system with 45 points and 39 cross-type AF points, a high ISO up to 102 400, an LCD screen 3-inch Clear View of type II, a dual DIGIC 4 (as the 7D), shooting burst at 10im/sec …

In short, a very nice movie mode, and I regret that Canon did not put so much love in the design of 7D .

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 transmission 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), RAW-M (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 tonalites 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 uses 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 more accurate colors when shooting under low color temperature light sources such as household tungsten lamps.

The EOS-1D Mark IV Digital SLR features Canon’s Peripheral Illumination Correction function Which correct 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 II Clear View LCD screen with 920.000 dot / VGA resolution and a wide 160-degree viewing angle for enhanced clarity and more precise color when reviewing pictures and shooting video. The new in-camera feature helps copyright information professionals secure control over images copyright by setting 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’s Auto Lighting Optimizer

Action photography truly is all about speed, fast capturing a 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 have clear and detailed as they actually appear. By optimizing brightness and contrast in-camera, Canon’s system ALO Significantly Reduces the need for post-production optimization, gives photographers and picture quality they can take directly to press. Demanding professional photographers who tested ALO clearly “stated that this one will feature Reduce their post-production 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 enhances 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 frame, including the mirror box, are constructed with magnesium-alloy, one of the strongest metals available and rigid 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 wireless transmitter IIA is an extremely small and versatile device that offers professional photographers a wide range of digital connectivity options including Ethernet and IEEE802.11a/b/g, ideal for commercial and studio work. In addition to adding the ability to connect to wireless networks over 802.11, the new WFT-E2 IIA adds a wealth of new features to the professional 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 data to coordinate the images.
