The Canon EOS 1D Mark IV, the latest evolution of Canon’s DSLR line, was released in December 2009. Along with the higher resolution 1Ds Mark III, the IV is the faster-shooting member of Canon’s one,two punch for professionals and serious amateurs (really serious given the $4,999 USD MSRP). The camera’s predecessor, the 1D Mark III, remains on the Canon website at the time of this review (at a relatively bargain-priced $3,999), but the IV has some significant specification differences to consider when deciding which camera is the better deal.
