There are interesting findings on the Canon EOS-1D Mark II N review by CNET where they write, ' Because of its high resolution and superb image quality, the Mark II will demand a lot from your lenses.' 'the Canon EOS-1D Mark II files are smooth and show almost no noise at ISO 100 and ISO 200; even ISO 400 and ISO 800 look very good. There is no sign of the banding that plagued images from the EOS-1D. As with most dSLRs, however, you must be careful not to underexpose your images.'

'Canon has managed to improve all aspects of continuous-shooting performance for the EOS-1D Mark II N. It retains its fastest rated full-resolution drive speed of 8.5fps in optimal conditions, but Canon claims the buffer will now hold 48 JPEG images (up from 40), 22 raw files (up from 20), or 19 raw+JPEG before reaching capacity. In our tests, we managed to capture 257 small JPEGs at 8fps and 100 raw shots at 3fps before buffer crawl set in.
