The 1Ds Mark III is an engineering tour de force which, true to the -1 legacy, redefines the state of the art in no uncertain terms. An entirely new 21.1-megapixel full-frame  CMOS sensor delivers astounding image quality and creates new photographic possibilities. Dual "DIGIC III" Image Processors work in tandem to speed up data handling and camera operation, while further refining imaging performance. Tough, high-durability body and shutter designs, combined with the unique  Integrated Cleaning System, set new standards for professional dependability. Cutting-edge features-such as a large 3.0-inch LCD monitor with Live View Function, and a fast, precise 45-point AF system-make the -1Ds Mark III powerful and versatile. And, of course, the -1Ds Mark III is part of the unparalleled  System, which, with more than 50 EF lenses, 15 interchangeable focusing screens, and extensive wireless, remote control and lighting accessories, is the most advanced and powerful digital photography system in the world.
