You're right. It's so subtle in Ghostbusters that I never noticed it until the commentary track came out, around 1999?
Never once picked up on it in fifteen years of viewing.
Also on this topic, I was just watching a clip from Jaws (1975) and Spielberg used a rapid dolly/zoom to great effect when Brody sees the shark attacking Alex Kintner.
This made me think it would be interesting to see a supercut of all movies/directors that used this technique in chronological order.
And sure enough, someone's already done the bulk of the work for us. Found it on vimeo.
Jaws, Ghostbusters, and Goodfellas are all on here. Spielberg used it again in E.T. (1982).
