Took a search around to see if it had been posted before but couldn't find anything.
Noticed this when I first saw the movie in theaters, but couldn't give proof until I got a DVD copy. They did change the seen from the theater to the DVD copy, as the man with the camera was actually in Tony Stark's face at the start of the original scene.
Seems who ever was in charge of props didn't know that the MDF of the 100-400mm is 5.9 feet.
