This is the Hasselblad Film Magazine 70 for 70mm perforated film. It uses film cassettes which can be loaded with approximately 4.7m (185") of film to provide up to 70 frames per cassette in the 6 x 6cm format. This magazine is suited for large scale, high-volume shooting such as school portrait photography. The replacement film cassette is part #51039. Magazine 70 is available in either chrome or black trim.
NOTE: Magazine 70 can be used with all Hasselblad medium format cameras but cannot be combined with the prism viewfinders PM90 and PME90. The MK70 and MKWE metric cameras use specially designed film magazines for 70mm film.
