Has anyone seen any of these episodes? Its a good example of using 35mm adapters (and tilt lenses) on documentaries. Definitely gives the series a very different look. If you haven't, here is a link. Try to watch the quicktimes instead of the flash videos, as the compression is pretty bad. On TV they look awesome!
