So I was watching the behind the scenes featurette on the DVD and then there was one scene where Michael Bay was prepping up a shot in the city battle and then you see him kneeling down on one knee and then he looks through a small scope. It almost just looks like a long camera lens but without the camera. Its just the scope/lens part.
He can wear it around his neck.
I suppose it is for him to see what the shot would look like without the use of the camera.
Can someone tell me what that piece of equipment is called?
