Design and ergonomics

In magnesium alloy casing with dust and moisture resistant seals to protect the body, and a weight of 1,2 kg (excl battery), the EOS-1Ds Mark III features a menu which 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, meaning  photographers can 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. As well as a new dedicated ISO button, ISO is permanently displayed on the top LCD panel.
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.

The bright 3.0” LCD monitor provides 230K pixels resolution for precise framing and reviewing, while 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.

Picture Quality

With 21 Megapixels, you can achieve high resolution 20x20 inch prints, with greater enlargement possible for poster size prints. Images are processed at 14 bit colour depth for finer tonal gradations, and high quality images are ensured by effective noise reduction at high sensitivities and a low pass filter that combats false colour and moiré.
The sensor’s wide dynamic range can be set to preserve more detail from bright areas with the Highlight Tone Priority function.

Performance Features

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.
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. 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.

Dual "DIGIC III" processors drive the camera’s rapid performance, allowing near-instant start-up and response times.

Technology Features

Canon’s CMOS technology incorporates noise reduction circuitry at each pixel site, avoiding unneccessary charge transfer operations thus significantly speeding up the process of getting the signal to the image processor, reducing Noise generation  and limiting power consumption.

The DIGIC III image processor uses advanced image processing algorithms to ensure precise, natural colours, accurate white balance, and advanced noise reduction and its ultra-fast processing speed result in highly responsive camera operation and near-instant start-up times.
DIGIC chips work with a high speed DDR-SDRAM image buffer – reading, processing, compressing and writing image data fast enough to keep the buffer clear during long continuous shooting bursts.

The redesigned body cap prevents dust generation through wear on the cap itself in conjunction with Anti-static technologies and A Self-Cleaning Sensor Unit, the EOS 5D Mark II has extra protection against harsh environmental elements.
