After World War Two, and building on his experience building the HK-7 aerial reconnaissance cameras for the Swedish Air Force, a Swedish businessman set about designing his dream camera: a waist-level SLR that made 6x6 photographs on 120 film. The Rossex.
By 1948, it was ready. It was a beautiful camera designed by Sixten Sason, who also designed the original Saab car. It was a modular system with interchangeable lenses, film backs, and viewfinders. It had a focal plane shutter of stainless steel foil, with speeds up to 1/1600 sec, an array of Kodak Ektar lenses and was now called the Hasselblad 1600F.
