Engadget also reports that Amazon has inadvertently activated the page for Canon's 21.1 megapixel EOS 1Ds Mark III. If true, and there's no reason to disbelieve this, it's an 11 megapixel jump from their EOS 1D Mark III. This camera is designed for fashion photographers and commercial photo studios.
The new Canon sports a 36 x 24-mm self-cleaning CMOS sensor; a pair of DIGIC III image processers operating in parallel; improved 45-point advanced autofocus; 5fps continuous shooting (for bursts of up to 45 Large/Fine JPEGs or 15 RAW images); sRAW image support; 3-inch Live View LCD with 5x or 10x magnification; and CF, SD/SDHC storage options.
Amazon's website listed its price at $8,000 and that it will ship on December 10th.
