In 1953, a much-improved camera, the 1000f was released. In 1954, they took the 1000f design and mated it to the groundbreaking new 38 mm Biogon lens designed by Dr. Bertele of Zeiss to produce the SWA (Supreme Wide Angle, later changed to Super Wide Angle). Though a specialty product not intended to sell in large numbers, the SWA was an impressive achievement, and derivatives were sold for decades. Hasselblad took their two products to the 1954 Photokina trade show in Germany, and word began to spread.
