I. OVERVIEW 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

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 shoot

IV. DISCUSSION OF NEW AND IMPROVED FEATURES New 21.1 Megapixel, Full The 35mm full-frame CMOS sensor of the EOS-1Ds Mark III has been developed and Frame CMOS Sensor 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 megapixel

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 Time process, optimized pixel amp, and optimized reading circuit. Thanks to optimized photo diode construction and finer process- LPF Co

With the EF 24mm f/2.8 or EF 28mm f/2.8 lens, cross-type focusing will be active with the 13 AF points shown in the diagram; the remaining 6 AF points will be horizontal line-sensitive at f/5.6. All other EF lenses take full advantage of the AF sensor.

The EOS-1Ds Mark III is compatible with UDMA (Ultra Direct Memory Access), a new CF card specification (CompactFlash Specifications Revision 4.0) enabling high-speed writ- ing to the CF card. With a UDMA CF card, the high-speed data transfer is about twice as fast as the EOS-1D Mark III (about 3 times as fast as the EOS-1Ds Mark II). Although the EOS-1Ds Mark III has twice as many pixels as the EOS-1D Mark III, the writing speed per file is about the same as the EOS-1D Mark III, which is quite a

As with the EOS-1Ds Mark II, the superimposition display consists of the lead-in compo- nent, integrating the dichroic prisms (SI prism 1 and 2) with the pentaprism and the illu- mination (SI-LED), liquid-crystal (SI-LCD), and the eyepiece lens. Compared with the EOS-1D Mark III’s dichroic mirror system, the dichroic prism system can have a more compact light path in the lead-in component. This contributes to a higher viewfinder magnification. SI lens 2 Viewfinder Optics 2 SI prism 1 SI mirror

New UDMA Compatibility UDMA (Ultra Direct Memory Access) is a new specification for CF cards (Compact Flash Specification Revision 4.0) to enable high-speed writing to the card. With a UDMA-com- pliant CF card, the data transfer speed is twice as fast as with the EOS-1D Mark III, and the writing speed is on par with the EOS-1D Mark III (and about 3 times as fast as the EOS-1Ds Mark II) even though the pixel count is twice as large.

Having the same drive mechanism as the EOS-1D Mark III, the EOS-1Ds Mark III’s maxi- mum continuous shooting speed is 5 fps in both the One-Shot AF and AI SERVO AF modes. This rate is achieved with 8-channel reading, DDR-SDRAM (twice the capacity of the EOS-1Ds Mark II’s), and Dual “DIGIC III” Image Processors. Continuous shooting speed can also be adjusted with C.Fn III-16 [Continuous shooting speed] as follows: High-speed continuous within 2 to 5 fps, and low-speed continuous within 1 to 4 fps

The dimensions (W x H x D) of the EOS-1Ds Mark III are: 156 x 159.6 x 79.9mm/6.1 x 6.3 x 3.1 in. It is 3mm taller than the EOS-1D Mark III. The body-only weight is approxi- mately 42.7 oz./ 1,210g, approximately 1.9 oz./55g heavier than the EOS-1D Mark III but 0.18 oz./5g less than a body-only EOS-1Ds Mark II. The difference in this case becomes more pronounced when the respective batteries are added in: 48.9 oz./1,385g for the EOS-1Ds Mark II vs. 54.9 oz./ Location of Major Water-resistant Meas
