Beware of old super-8 camera's which cannot take f.e. the new filmstock Kodak 64T. The Canon 1014, 814 (XL-S), Nizo's (except 136, 148, 156), old Bauer 6,8,10 Royal (not the E!) can take different stock. Usually, most old can only take 25, 40 and 100 ASA.
For a list of color and black/white stock, take a look at my new website: www.super8camera.com
