Stanley Kubrick was famously precise about his equipment. His most famous and special items of equipment were the Carl Zeiss F0.7 lenses which were remounted for him by Ed DeGullio to fit a specially modified Mitchell BNC camera. These lenses were hugely difficult to operate - requiiring a full 5 rotations to allow the camera to rack over from the viewing position to the filming position. These lenses have an exquisite shallow depth of field, as well as a soft bocka unseen in lenses since.
