I think only that season finale episode where House is stucked with a woman on debris of a parking lot, and he refuses to amputate her leg to release her. As it was a very tight space they´ve used the 5D.
My friend has a 5D with a variety of lens (I love the fish eye) and I think the price tag is a bargain for the quality of the product.
As I´ve said, just look at this guy (the author of the time lapse video) pics of the volcano:
