Beautiful pictures. I love the quality of that camera and wish I could afford it. Have you gone to Vimeo.com and typed in either the Canon 7D or the 5DMKII in the search window and looked at the video capability of those two? Both are amazing cameras and I don't see that much difference between the lower priced 7D compared to the 5D. I just bought the new Panasonic Lumix FZ35. It will be a while before I can swing an SLR like the 7D.
I assume that those are your shots so keep up the good work.
I've seen several comparison videos between expensive ($15k+ )dedicated video cameras and the Canon5D, 7D and even the Panasonic GH1. I guess if you are viewing the videos on something other than an internet HD playback there is probably a difference, but I am always amazed at the quality the new SLR and even bridge cameras can produce.
