Unique Photo: Canon 1D Mark IV Versus Nikon D3S

Last week at Coastal Sports in Long Island, Unique Photo put two of the best cameras in the hands of two top-tier professional photographers. Canon and Nikon are the powerhouses in the digital SLR market, and their flagship cameras represent the finest sports photography cameras ever made.  The highly anticipated Canon EOS 1D Mark IV has just started shipping, and Nikon’s D3S has been available for about one month.
