Canon has published a white paper for the 5D Mark II and 50D cameras. (White Papers are comprehensive documents detailing system enhancements — and the technological developments behind them.)
It is available for download from Canon’s website.
For more info on these cameras, see Photography Bay’s Canon 50D Reviews and Resources and Canon 5D Mark II Reviews and Resources.
These links blow…none of ’em work
@ Peter – I just tried the link to Canon’s site and had no problems.
