Canon has brought the best of the EOS-1D Series of digital cameras into one phenomenal model: the new flagship of the EOS line, the Canon EOS-1D X Digital SLR Camera. Its full-frame 18.1 Megapixel CMOS sensor and all-new Dual DIGIC 5+ Image Processors deliver high quality image capture at up to 12 fps (14 fps in Super High Speed Mode) and a powerful ISO range of 100 - 51200 (up to 204800 in H2 mode) provides sharp, low-noise images even in the dimmest low-light conditions. An all-new, 61-Point High-Density Reticular AF and 100,000-pixel RGB Metering Sensor that uses a dedicated DIGIC 4 Image Processor, makes the EOS-1D X reach new levels of focus speed and accuracy delivering advanced tracking even for the most challenging shooting situations. Taken all together, the EOS-1D X's improved HD video capture, numerous connectivity options, combination of processing power and durable construction, including shutter durability tested to 400,000 cycles, make it the ultimate EOS.
