Canon EOS-1Ds Mark III Preview
Phil Askey, August 2007
The EOS-1Ds Mark III becomes the seventh Canon professional EOS-1D series digital SLR, although only the third of the 's' suffix sub-category which indicates a full frame sensor. Three years since the last EOS-1Ds, the Mark II, the Mark III pushes digital SLR resolution over the twenty megapixel barrier with specifically twenty-one-point-one million pixels (5616 x 3744) on its 36 x 24 mm (full 35 mm frame) sensor. Canon also claim to have increased the 'light gathering efficiency' of the sensor by reducing the amount of (wasted) space between microlenses, hence despite the resolution increase the Mark III still provides sensitivity up to ISO 3200 (with boost enabled).
As well as increasing resolution Canon has pushed continuous shooting up a step with five frames per second over the Mark II's four frames per second. This means that at full speed the two DIGIC III image processors are dealing with an impressive 185 MB/sec. Other improvements include the larger screen, Live View, a fourteen-bit A/D converter and fourteen-bit RAW files, UDMA Compact Flash support (up to 45 MB/sec) and a whole range of features (such as dual storage slots and Picture Styles) inherited from the EOS-1D Mark III.
Model line history
The EOS-1Ds Mark III represents a 26% increase in resolution over the EOS-1Ds Mark II which in turn represented a 50% increase in resolution over the original EOS-1Ds.

* New or changed compared to the EOS-1Ds Mark II Jump to: Amstelveen, The Netherlands, 20 August, 2007: Canon raises the stakes in the professional photography market with the launch of the 21 Megapixel, 5 frame per second EOS-1Ds Mark III. Delivering 14-bit depth resolution from a newly developed 35mm full frame CMOS sensor, Canon’s new flagship digital SLR produces files that convert to over 100MB uncompressed 16-bit TIFF, setting a new benchmark in image resolution and sharpness for 35mm-format digital photography. As well as producing outstanding colour rendition, Dual DIGIC III processors drive 5 fps continuous shooting for up to 56 Large JPEGs (12 RAW) – unrivalled by any other camera at this resolution. This capacity to shoot such large images uninterrupted is regarded as a big driver in switching studio photographers to the EOS platform. The EOS-1Ds Mark III inherits the new technology platform introduced earlier this year in the EOS-1D Mark III, including 63-zone exposure metering, 19 cross-type auto focus system, a 3.0” LCD with Live View mode and EOS Integrated Cleaning System. The Highlight Tone Priority function expands dynamic range for more depth and detail in bright areas. The launch is supported with the announcement of Canon’s new ultra wide-angle lens, the Lens 2. “Taking image quality and versatility to unprecedented levels, the EOS-1Ds Mark III redefines commercial photography conventions”, said Karz Suzuki, Head of Canon Professional Services. “The camera will strengthen Canon’s popularity amongst professional studio photographers. Culminating 20 years of EOS development, the EOS-1Ds Mark III represents a definitive moment in our company’s photographic history.” Key features Image quality The EOS-1Ds Mark III produces files that exceed the standard resolution requirements of leading agencies and stock libraries. The third generation CMOS sensor incorporates a new pixel design with on-chip noise reduction circuitry to ensure high image quality all the way to ISO 1600. 14 bit A/D converters provide a total colour depth of 16,384 tones per pixel - delivering smoother gradations and more accurate colour reproduction. The option to expand to H:3200 will be welcomed by professionals working in churches and sensitive situations where the use of flash is not permitted or desired. Where discretion is paramount, a silent drive mode delays shutter re-cocking for as long as the shutter release remains depressed. Highlight Tone Priority mode gives wedding and landscape photographers the option to boost dynamic range for highlights when shooting above ISO 200 – reproducing more tonal detail from wedding dresses, clouds and other bright objects. Precision and control The auto focus system includes 19 cross-type sensors with sensitivity up to f/2.8, spread across the AF area to better accommodate off-centre subjects. An additional 26 AF assist points help with AF tracking accuracy. The control layout includes a dedicated AF-ON button on the back of the camera, allowing users to instantly switch auto focus on when composing. The viewfinder is now brighter with a wider angle of view, while the 63-zone metering system gives photographers a greater degree of control over exposure. New LCD with Live View The bright 3.0” LCD monitor provides 230K pixels resolution for precise framing and reviewing. Live View mode displays a real-time image on the LCD, including a selectable grid overlay and a live histogram that simulates image exposure. For the studio environment, remote Live View lets the photographer compose, adjust settings and capture the shot from a PC using the supplied EOS utility software. New controls and menu The EOS-1Ds Mark III’s menu incorporates a tab structure that eliminates scrolling for vastly improved readability and ease of use. Improving on previous models, personal settings and custom functions are consolidated into 57 custom functions grouped into four logical categories. Photographers can also now see at a glance any default setting changes. The My Menu option allows photographers to store frequently used settings on a separate menu for immediate access. Settings for recently released accessories such as the Speedlite 580EX II and the Wireless File Transmitter WFT-E2 can be controlled directly from the LCD. Along with a new dedicated ISO button, ISO is permanently displayed on the top LCD panel. Reliability Shutter durability is increased by 50% to 300,000 cycles. A magnesium alloy casing with dust and moisture resistant seals protects the body. The EOS Integrated Cleaning System reduces, repels and removes dust from the sensor to significantly limit the need for manual cleaning. To avoid image loss, a warning alarm sounds if the memory card door is opened while images are still being written. Connectivity Interfaces include video out (for display in both NTSC and PAL formats – with the Live View mode ideal for live display to clients during the shoot) and USB 2.0. To prevent the USB cable becoming accidentally dislodged during shooting, a special connection secures it to the camera body. Compatibility and accessories As well as full compatibility with all EF lenses and EX Speedlite flashes and accessories, the EOS-1Ds Mark III is supported by the recently released Wireless File Transmitter WFT-E2. The WFT-E2 enables secure wireless uploads to FTP servers as well as remote access via HTTP and PTP protocols. The unit also connects wirelessly to external storage media and supports GPS tagging when used with a portable GPS device. For assignments where image protection and authenticity are crucial, the EOS-1Ds Mark III is compatible with the Original Data Security Kit OSK-E3. New lens Today’s launch coincides with the release of the EF 14mm f/2.8L II USM: Canon’s new professional L-series ultra wide-angle lens for the photographer requiring a slightly different perspective. As with many L-series lenses and the Speedlite 580EX II, the EF 14mm f/2.8L II USM incorporates environmental sealing to match that of the EOS-1Ds Mark III, creating a fully weatherproof camera system. Aspherical and UD lens elements produce exceptional image quality with improved corner-to-corner sharpness. The ring-type USM delivers fast, silent auto focus with full-time manual focus override. A circular aperture produces pleasing bokeh at wide apertures and Super Spectra coatings suppress ghosting and flare by suppressing internal reflections from lens element and sensor surfaces. Software The EOS-1Ds Mark III is packaged with a comprehensive software suite to streamline the photographer’s workflow. This includes Digital Photo Professional (DPP) RAW conversion/processing software for complete RAW image processing control. DPP also integrates with camera features such as the Dust Delete Data and Picture Style. The camera also comes with EOS Utility, ImageBrowser/Zoom Browser and Photostitch. CMOS Canon’s CMOS technology is one of the company’s key competitive advantages, with 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. EOS Integrated Cleaning System The EOS Integrated Cleaning System combats sensor dust in three important ways: Reduce, Repel and Remove. 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. Picture Style Picture Style pre-sets simplify in-camera control over image qualities. Picture Style pre-sets can be likened to different film types – each one offering a different colour response. Within each selectable pre-set, 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 pre-sets applied to a RAW image can be revised with Canon’s Digital Photo Professional software. The six presets include: The User Defined Picture Style can be used to store up to three customized pre-sets, or any of the pre-sets available for download from Canon’s web site at www.canon.co.jp/Imaging/picturestyle/file/. Additionally, users can create their own custom Picture Style pre-sets using the supplied Picture Style Editor 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 the immediate application of image adjustments, giving control over RAW image variables such as white balance, dynamic range, exposure compensation and colour tone. Images can be recorded in camera with sRGB or Adobe RGB colour space. Digital Photo Professional supports sRGB, Adobe RGB, ColorMatch 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 combination and applied. Improvements in the latest version of Digital Photo Professional include three times faster image previews, an enhanced Noise Reduction tool and simultaneous batch processing of TIFF and JPEG images. EOS Utility The latest version of EOS Utility provides essential support for remote shooting control, camera configuration, remote Live View support and configuration of the new Original Data Security Kit OSK-E3 and Wireless File Transmitter WFT-E3 accessories. EOS Utility can be configured to monitor ‘hot’ folders, automatically renaming and moving incoming images to a structured file system – ideal for Wi-Fi transfers, or for commercial and studio photographers who want to shoot direct to a computer.
