What is the exact type of professional camera they use to make feature movies.?

Question

You know the type of cameras they used to make movies like 300 or spiderman 3 or other hollywood films.

Answer 1

There are several, though panavision and cinamax are the top ones and they use different sizes of film from 35mm up to 75mm. You won't see much digital full featured films for a while yet as the resolution sucks compared to film but digital is (along with computer generated) making several in roads in to the industry.

Answer 2

Those are usually Panavision cameras---VERY expensive.
