EOS-1Ds Mark III – the professional workhorse

Introduced in August 2007, the 21-megapixel EOS-1Ds Mark III is the professional workhorse camera for all shooting situations. With many of the same features as the EOS-1D Mark III, the EOS-1Ds Mark III combines the highest resolution available in a 35mm format camera, with a 5fps shooting speed to ensure it isn’t just confined to the studio. These features make it equally suitable for fashion, portrait, wildlife, wedding and sports photography.

Who is it for?

The EOS-1Ds Mark III is the studio photographers’ workhorse. While the 35mm format does not confine this camera to the studio, being an equally capable performer outside, it is tailored to those shooting in commercial and advertising markets where high resolution and excellent image quality are paramount.

Key features

21.1 Megapixel full-frame CMOS sensor
Dual DIGIC III processors
5fps shooting speed
High precision wide-area AF
14bit A/D processing
3-inch LCD with Live View
EOS Integrated Cleaning System

The inclusion of the integrated cleaning system, the first on a full-frame digital camera, will see you spend more time shooting and less time dust-spotting on the computer in post-production. This is an advantage to all, but is especially useful for professionals where time is critical and deadlines short.

The full-frame CMOS sensor makes lenses function as expected – wideangle lenses retain their field of view, and the advanced in-camera processing ensures that image noise remains characteristically low.

Like the EOS-1D Mark III, the EOS-1Ds Mark III mates perfectly with the Canon Speedlite 580EX II flashgun to provide complete weather sealing. Long considered the benchmark cameras for use in harsh environments, the lightweight magnesium alloy body, sealed buttons and joints and 300,000 shutter count ensure the EOS-1Ds Mark III continues the Canon tradition of durability.

A redesigned autofocus system with 19 user-selectable cross-type sensors and 26 focus-assist points help the camera to lock-on and track difficult or fast moving subjects even in low light. Using off-centre focus points focusing is improved as all user selectable points are now cross-type.

14-bit A/D processing and highlight tone priority ensure smoother tonal gradations and greater colour fidelity. The increase from 12bit to 14bit increases the total colours per channel from 4,096 to 16,384 - this results in increased dynamic range in your images and better tonality, especially in highlight regions. It is especially useful for situations such as photographing the bride’s dress at a wedding.

New UDMA memory card compatibility ensures that despite a file size about twice that of the EOS-1D Mark III, the total time taken to write an image to the memory card is about the same, meaning more shots before the buffer fills up.

With such an extended feature set and class-leading resolution, the EOS-1Ds Mark III enters the areas previously the preserve of medium format digital backs. With the flexibility of the 35mm format and the extensive accessory and lens list of the EOS system, it sits apart as the ultimate tool for any photographer looking for the highest image quality and resolution.

DIGIC processing
The DIGIC processors have been the heart of the EOS digital camera models for several generations. The DIGIC III processor in the EOS-1Ds Mark III has been teamed with a partner to provide two working simultaneously. This has the ability to process images faster and with more complex algorithms.
EOS Integrated Cleaning System
Dust is a fact of life with digital cameras. The EOS ICS help minimise dust entering the camera, repel dust that does get in and remove dust that’s made it onto the sensor.
CMOS sensor
Canon pioneered the design and manufacture of CMOS sensors for digital cameras. To this day it not only uses, designs and builds its own CMOS sensors, but it also designs and builds the machines used to produce the sensors. This gives Canon complete control over the production process of the camera and ensures that everything works together harmoniously.
Wide-area AF
The composition and exposure may be perfect, but if it’s not in focus, the image is ruined. The wide-area AF with 19 cross-type AF points provides flexibility in composition and allows you to keep track of a moving subject with ease.
