I love that camera!!! It is an old Arriflex camera from the 1960's called the Arri M, and an old Angenieux 12-120 or 12-150mm zoom! MMM variable speed motor at 48ish fps for slowmotion if they have adequate voltage. I bet there is a 100 foot daylight spool of ... hmmm... Kodak 50D would be my guess. Have to put way to much ND with the 250D. Great small portable package perfect for shooting sports in the middle of nowhere. That paired with a Bolex and you are set.
