EOS-1Ds Mark III, replacing the 16.7-megapixel EOS-1Ds Mark II, is a professional digital SLR camera designed to meet the rigorous demands of professional portrait, merchandise, and landscape photographers.

Incorporating Canon’s 35 mm full-frame, 21.1-megapixel CMOS sensor, the EOS-1Ds Mark III realizes an exceptional level of image quality through its high image resolution, low noise, and rich color gradation, supporting an ISO range from 100 up to 1600.*1 The 35 mm sensor size allows users to fully utilize the angles of view offered by all Canon EF lenses,*2 allowing for unrestricted lens performance and a shooting feel on par with that of film SLR cameras.

In addition, the EOS-1Ds Mark III is equipped with the dual DIGIC III high-end image-processing system, enabling processing of even higher resolution image data at a speed approximately 4 times faster than the previous model. The technology also makes possible a continuous shooting speed of approximately 5 frames per second for up to 56 large JPEG images or up to 12 RAW images in a sequence. The model further realizes outstanding functionality by employing a high-speed, high-precision Area AF sensor of 19 cross-type points (f/2.8 or faster lenses) plus 26 assist points (f/5.6 or faster lenses), and a newly developed high-performance viewfinder that achieves 100% coverage and 0.76x magnification, the highest viewfinder magnification in its class.*3

The EOS-1Ds Mark III caters to the needs of pro users by offering outstanding resilience, boasting a shutter capable of withstanding 300,000 cycles. The combination of dust- and water-resistant EF lenses and accessories and Canon’s EOS Integrated Cleaning System, a complete dust reduction system, enables the camera to deliver unfailing performance under even the most grueling conditions.

Expanding upon the highly acclaimed functions of the EOS-1D Mark III launched in May 2007, the EOS-1Ds Mark III also incorporates such high-end features as a refined user interface featuring two Live View modes, which offer enhanced performance for studio photographers, and a large 3.0-inch LCD monitor, as well as a variety of system accessories to provide for a wide range of professional photography needs. The Canon EOS-1Ds Mark III will be available in Japan from late November at an open price. Canon has set initial production at 2,500 units per month.
