Canon EOS-1Ds, 11.1 Megapixel, Interchangeable Lens, Professional, SLR, Digital Camera A full-frame CMOS sensor. This is what professionals have been asking for.The EOS-1Ds advantage starts at the imaging sensor.And what a tremendous breakthrough it is. A full-frame CMOS sensor manufactured by Canon with an imaging area of 24 x 36mm, the same dimensions used by full-frame 35mm SLRs. It has 11.1 million effective pixels with a maximum resolution of 4,064 x 2,704 pixels. This is almost double the resolution currently considered state-of-the-art by most professionals. Unprecedented file sizes, processed with unprecedented quality at unprecedented speed.The EOS-1Ds's imaging engine is one of the keys to its exceptional image quality. This advanced "chip" processes and assembles image data captured by the sensor to achieve the same color accuracy and wide tonal range as regular film-based cameras. And even with almost twice the pixel resolution of previous pro cameras, the imaging engine still supports a 10-frame buffer memory at framing rates up to 3 fps! 3 fps continuous shooting for up to 10 shots, even at the highest quality setting.Fast data reading by the CMOS sensor and rapid imaging processing by the high-performance imaging engine together achieve a continuous shooting speed of 3 fps, even at the highest quality setting. Canon has developed 2-channel reading to ensure that the EOS-1Ds delivers incredible 11.1 million pixel resolution with 3 fps shooting speeds into a reality. Your wide-angle lenses act like wide-angle lenses.Finally, every EF lens will work the same on a digital SLR as it does on your 35mm film cameras, with the same coverage. It's one less thing for the pro to think about on location, and it's one more thing to ease the transition from film into digital. Even for wide- angle shooters. Battery life has been improved by reducing power consumption.
