The EOS-1Ds Mark III is a digital SLR camera body by Canon Inc. of Japan. The Canon EOS 1Ds Mark III is successor to the EOS-1Ds Mark II. 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 features 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 features many technologies first seen in the Canon EOS-1D Mark III, such as the 63-zone exposure metering, 19 cross-type auto focus system, a 3.0" LCD with Live View mode and EOS Integrated Cleaning System.

Features

Image quality

The EOS-1Ds Mark III features a 21-megapixel sensor. It is larger than 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. It can shoot in 3200 ISO when necessary. The 1Ds Mark III also features Highlight Tone Priority mode, which boosts the dynamic range for highlights.cite web | url=http://reviews.cnet.com/digital-cameras/canon-eos-1ds-mark/4505-6501_7-32572245.html?%5E$ | title=Canon EOS-1Ds Mark III | last=Ryan | first=Philip | date=2008-02-25 | accessdate=2008-03-22 | publisher=cnet.com]
