While trawling the web, I found a gem of a video, produced by Parker Walbeck. It's an inspirational piece depicting great gymnastics, shot on the 5d Mk II and the T3i (600D). What impresses me most about this video, aside the pleasant story and superbly skilled talent, is the editing and the way it was shot. Looking at other work by Parker, though, I can't be surprised - his videos always demonstrate high level of cinematographic skill.
This one comes highly recommended! :)
