Canon also takes on the Nikon D3 and D700 with this new high-resolution sensor,I’ll have to leave it to you whether the Canon 5D Mark II maintains the same level of magic, but what’s sure is that Canon’s attention to the high ISO issue has produced a camera whose high resolution images stand up to substantial enlargement even at the highest settings. The 5D Mark II also gives you plenty of freedom to play confidently with ISO settings, moving with confidence up to ISO 800 with nearly no loss of detail and ridiculously low chroma noise as the 5D Mark II also offers an expanded ISO range from 50 to 25,600. While the former two cameras achieve 100 to 25,600 expanded, they do it at 12.1 megapixels.

The body-only weight of the 5D Mark II is 1.78 pounds (810g), and dimensions are 6 x 4.5 x 3 inches (152 x 113.5 x 75mm). These measurements are essentially identical to the original Canon 5D. Canon has also included the new DIGIC 4 processor, capable of handling the extremely large 14-bit RAW images at the new high speed of 3.9 frames per second.
The new 920,000- LCD introdudotced on the Canon 50D also makes it over to the new Canon 5D Mark II, something the new 5D’s competitors also have in their arsenal. The 5D Mark II also shares the Live View features found on the 50D, complete with contrast-detect autofocus and silent shutter modes.
