I believe it was one of the first to market with that ability.
I may be mistaken and I have not checked into it lately but I thought the first 5D did not offer that option. I was not aware there was a mark II, unless that was the long name for the first one that came out 2 years ago or so. Or I could be completely wrong and and did not read all the info the first time
