Hello friends after many years I picked up my Brain super8 camera and discovered it had died a death i replaced it with a Canon 814, but am concerned to put a roll though it again after the last one was basically developed as a very expensive clear frame. I am picking up new 625 batteries and am interested in whether I should rely upon the electronic eye of a 40 year old camera or whether I should run it in manual. all ideas welcome at this stage please -
