The EOS-1Ds Mark III is a digital SLR camera body by Canon Inc. of Japan. it was first Launched in Amstelveen, The Netherlands on 20 August 2007.[citation needed] The Canon EOS 1Ds Mark III is successor to the EOS-1Ds Mark II as Canon’s flagship DSLR. A full-frame 21.1 megapixel CMOS sensor (the highest pixel count available as of 2007 in a 35 mm-equivalent digital SLR) with 14 bit A/D converters for a total colour depth of 16,384 tones per pixel. It boasts a three-inch LCD screen, capable of "Live View," and dual DIGIC III processors allowing it to shoot at up to five frames per second. The EOS-1Ds inherits many of its new technologies from the Canon 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. A professional grade camera body, the EOS-1Ds Mark III is large, ruggedly built, and is dust and weather-resistant.

[edit] Features

[edit] Image quality

The EOS-1Ds Mark III’s 21 megapixel sensor produces image files that exceed the standard resolution requirements of leading agencies and stock libraries. The upgraded sensor is a significant improvement over the 16.7 megapixel sensor seen in the Canon EOS-1Ds Mark II. The CMOS sensor incorporates a new pixel design with on-chip noise reduction circuitry to ensure high image quality up to ISO 1600.[citation needed] 14 bit A/D converters provide a total colour depth of 16,384 tones per pixel. The inclusion of H:3200 allows professionals to continue shooting within sensitive situations where flash is not permitted. 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.[1]

[edit] Auto focus

The new autofocus system is similar to the version seen in the Canon EOS-1D Mark III. The auto focus system includes 19 cross-type sensors at f/2.8, spread across the AF area.[1] The 1D mark III is targeted at professionals who require a high shooting rate (up to 10fps in the EOS-1D Mark III) for example sports, while the EOS-1Ds Mark III is intended for studio use where a high resolution has compromised the shooting rate. An additional 26 Auto Focus assist points help accuracy. The control layout on the back of the camera body includes a dedicated AF-ON button, allowing users to instantly switch auto focus on when composing an image. 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.[citation needed]

[edit] LCD and live view

The back of the camera includes a 3.0", 230K pixel LCD monitor, slightly larger than the 2.5" display of the Mark II. Live View is a mode which uses this LCD as an electronic viewfinder, with optional grid overlay and histogram. When the camera is tethered to a computer this mode can be used to compose, adjust and capture images using software supplied with the camera.

[edit] Connectivity

The EOS-1Ds Mark III connectivity ports:

[edit] Compatibility

The camera is compatible with Canon’s extensive range of EF lenses and EX Speedlite flashes and WFT-E2 wireless file transmitter. The WFT-E2 enables wireless uploads FTP servers as well as remote access using HTTP and PTP. The wireless file transmitter also connects to an external storage device, allowing images to be transferred from the camera without an internal memory card. Canon has implemented the Original Data Security Kit OSK-E3 into the EOS-1Ds Mark III which protects and authenticates the image.

Canon announced a new ultra wide-angle lens which coincided with the release of the EOS 1Ds Mark III.

[edit] Software

The EOS-1Ds Mark III is packaged with an extensive software collection including:

[edit] Firmware update

Canon occasionally releases a firmware update that fixes bugs in the camera software. Canon has a Firmware Update Page where users can download the latest release.[2]

[edit] Reliability

Canon has introduced several different features improving reliability of the EOS-1Ds Mark III over its predecessors:

  • Shutter durability increased to 300,000 cycles
  • The EOS Integrated Cleaning System prevents and removes dust from the sensor, limiting the need for manual cleaning
  • Dust and moisture resistant seals around a magnesium alloy casing protect the body
  • An alarm sound is activated if the memory card door is opened while images are being written preventing loss

As of 20 February 2008 there are reports of some cameras having misalignment between the image sensor and the viewfinder/prism assembly. Canon is reported to have acknowledged the problems and is correcting affected cameras.[3]
