The Canon EOS-1Ds Mark III is a new, top-of-the-line, professional DSLR autofocus camera with a 35mm full-frame, 21.1-megapixel CMOS sensor. It was developed in parallel with the totally new EOS-1D Mark III, so the cameras are similar in many respects. For example, the operation procedure, LCD monitor, menu functions, and playback functions are all the same as those of the EOS-1D Mark III.
The main differences reside in the 35mm full-frame sensor and related features of the EOS-1Ds Mark III, such as the viewfinder optics and the top cover, although other dis­tinctions will be made in this white paper.
EOS-1Ds Mark III: Specifications Different from EOS-1D Mark III
When the EOS-1Ds Mark III is compared to the camera it succeeds, the EOS-1Ds Mark II, the differences are much more substantial. The new camera has higher resolution, better image quality (from 14-bit D/A conversion vs. 12-bit, and DIGIC III vs. DIGIC II),
I. OVERVIEW 3
a higher framing rate and larger burst capacity, more precise AF, professional Live View Function, a 3.0-in. LCD monitor (larger images and larger, more legible font size), the EOS Integrated Cleaning System, a more convenient operating system, as well as many other features summarized in the next section.
The EOS-1Ds Mark III is intended, most obviously, for professional studio photographers and landscape photographers, but its 5 fps speed will attract sports, fashion and high-end wedding shooters, too. It is a complete imaging tool, with a host of extraor­dinary features shared with EOS-1D Mark III and, indeed, the entire Canon EOS System, meaning that almost any photographer for whom ultimate image quality is the bench­mark for camera selection will find the EOS-1Ds Mark III deeply appealing. It is a most worthy successor to the EOS-1Ds Mark II.

IMPROVED FEATURES
New 21.1 Megapixel, Full
Frame CMOS Sensor
The 35mm full-frame CMOS sensor of the EOS-1Ds Mark III has been developed and manufactured by Canon. Its 6.4µm pixels take advantage of a host of Canon R&D advances to achieve its speed, resolution and image quality. The following features make the EOS-1Ds Mark III the highest performing digital AF SLR camera:
• 35mm full-frame digital AF SLR with the world’s highest resolution, approximately 21.1 megapixels*
• Wide ISO speed range (ISO 100- 1600, L: 50, H: 3200)
• Low noise (same level as EOS-1Ds Mark II)
• High-speed signal reading (approximately 5 fps)
• Low power consumption
• Live View Function
*For 24x36mm format as of August 20, 2007.
CMOS Sensor (Actual Size)
Although the pixel size is about the same as that of the EOS 30D, the ISO speed range is the same as that of the EOS-1Ds Mark II.
By optimizing the gap between the on-chip microlenses, reducing the height from the photodiode to the microlens, and improving the fill factor (photo diode area divided by pixel size) by applying the micro-rule that improves the performance of the exposure device, light-gathering efficiency has been improved.

newly-developed noise reduction technology combine to remove noise effectively. To achieve even less noise, the EOS-1Ds Mark III has a new output amp that attains both high speed and low noise. Low noise is also achieved with an improved manufacturing process, optimized pixel amp, and optimized reading circuit.
Thanks to optimized photo diode construction and finer process­ing, the photo diode can still accumulate enough light to function exceptionally well. At low ISO speeds, the dynamic range is about the same as that of the EOS-1Ds Mark II.
As with the EOS-1D Mark III, single-line, 8-channel parallel reading is employed. With a low-noise, high-speed output amp, a continu­ous shooting speed of approximately 5 fps is attained, even with approximately 21.1 megapixels with which to contend.
The infrared, low-pass hybrid filter in front of the sensor consists of an infrared-absorption glass (including multiple coatings to reflect ultraviolet and infrared rays) and low-pass filter (phase plate sandwiched by two single-crystal plates). Other than opti­mization for the full-frame CMOS sensor, the specifications are the same as for the EOS-1D Mark III.

The state-of-the-art AF sensor in the EOS-1Ds Mark III is shared with the EOS-1D Mark III. The AI SERVO AF algorithm has been optimized to match the continuous shooting speed of the EOS-1Ds Mark III, approximately 5 fps. Also, due to the full-frame CMOS sensor, the Area AF coverage with respect to the viewfinder is slightly smaller than with the EOS-1D Mark III. The AF speed and predictive AF performance are the same as with the EOS-1D Mark III. All other AF-related specifi­cations not mentioned here are also the same as the best-in­class EOS-1D Mark III.
