The Canon EOS 5D Mark II succeeds the EOS 5D, launched in October 2005, which marked the first digital SLR camera for advanced-amateur users to incorporate a 35 mm full-frame CMOS sensor and enjoyed lasting market acclaim. The EOS 5D Mark II features a newly developed full-size 21.1-megapixel CMOS sensor that not only realizes outstanding resolution performance and rich gradation expression, but also offers an expanded standard ISO sensitivity range of ISO 100-6400*1 which, in extended mode, can be expanded to ISO 50, 12800 and 25600, enabling optimal performance in a diverse range of shooting situations.

The EOS 5D Mark II incorporates the next-generation DIGIC 4 image processor, which enables the high-speed processing of the increased amount of data generated by the high-pixel-count image sensor. The technology supports high resolution imaging performance while making possible a continuous shooting speed of up to approximately 3.9 frames per second*2 and bursts of up to approximately 310 shots.*3
