The EOS-1D Mark IV is the successor of the Canon EOS-1D Mark III and was announced on 20 October 2009, just four days after Nikon announced the D3s. It is currently the only Canon APS-H format DSLR to feature HD video recording at 1080p resolution.
It was discontinued in mid-2012 with the introduction of the Canon EOS-1D X, which replaced both the EOS-1D Mk IV and the EOS-1Ds Mk III.
It received a Gold Award from Digital Photography Review.
