The whole video is really good. Yeah, the key thing is the lens, but how this has cascading effects on the entire assembly is fascinating. The tripod alone is $20k because it must provide stable, smooth support for the 150 lb camera assembly. The video is full of second order effects like this that I, a non-photographer, could not anticipate. Similar to saying why is it hard to live in Antarctica, because it's extremely cold, but the details are what make this a meaty video.
