Yeah, it was the best of the best images hanging on the wall. I'm hoping that means it really was a 1Ds-Mark IV and that the 100-400 was really a 100-400 II, because I can't imagine they'd use the old 100-400 on that great new body.
Who knows though, it could have just been a typo.
I'm in touch with Canon quite a bit since they are sponsoring my printing series at http://www.ronmartblog.com/p/printing-series-articles.html
so if it was wrong, I would have expected them to call me on it and ask me to take it down. I kept waiting for the call and it never came, so it leads me to believe that it is either authentic or they are wanting a viral campaign to begin and I bit.
