Canon’s latest DSLR, the EOS-1D Mark IV, has emerged, and it’s got the Nikon D3S firmly in its sights. The EOS-1D Mark IV packs a 16-megapixel sensor, 45-point autofocus system, 10fps continuous shooting and 1080p Full HD video recording, together with not one but two of the company’s DIGIC 4 imaging processors. Like Nikon, too, Canon are waxing about their ISO range: the Mark IV boasts up to 102,400 ISO, though it’s more usually found playing in the 100 to 12,800 bracket.
