I think microcosmos was the first movie to use a macro camera which could pan a scene and still keep the focus. It came out in 1996 or so...http://www.amazon.com/Microcosmos-Jacques-Perrin/dp/B0000DZ3BS
Yeah, we watched Microcosmos in one of my Entomology classes at URI. You should definitely check out the whole thing; it's great.
