Mark III

Released in December 2007, the EOS-1Ds Mark III was the third and last of the Canon 1Ds full-frame line. When it was released, it held the title of the highest resolution full frame (35mm) dSLR, with a 21 megapixel CMOS sensor. More recent camera models from various manufacturers now exceed this. Compared to the Mark II, the Mark III added several new features, such as integrated sensor cleaning, Live View (an electronic viewfinder mode) and a larger 3.0" primary color LCD. The EOS-1Ds line was discontinued in mid-2012 with the introduction of the EOS-1D X, a full-frame body which merged the previous EOS-1D line of high-speed professional bodies with the EOS-1Ds line.
