What is the song from 2:00 minutes to the end of the video???

Music from "The Big Blue", Eric Serra ;)

I suppose he means it's a good tradeoff, because you get the most aperture out of the weight compared to other concepts.

what does jack mean?

cassegrains are jack of all trades if you got the money.

so are the cassegrains brighter now then the ones made years ago, & is there still foucs shift?
