DESC: The Canon EOS-1Ds Mark III is an engineering tour de force which, true to the EOS-1 legacy, redefines the state of the art in no uncertain terms. An 21.1-megapixel full-frame Canon 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 EOS Integrated Cleaning System, set standards for professional dependability.
