Hasselblad HK7 (Ross)

The HK7 (Ross) was a medium format camera produced by Hasselblad during World War II, from 1941 to 1945. Utilizing the 120 film format, this early camera represented an important product in the development of the Swedish manufacturer that would later become renowned for medium format photography. Though not among the company's most famous models, the HK7 (Ross) demonstrates Hasselblad's early commitment to medium format photography during a challenging historical period when resources were limited due to the wartime context. This camera represents a transitional phase for the company, predating their iconic 500 series that would later establish Hasselblad's reputation in professional photography.

The wartime production of the HK7 (Ross) likely influenced its design and materials, as many manufacturers had to adapt to resource constraints during this period. As a 120 format camera, it would have produced 6×6 or 6×4.5 cm negatives, providing the high-quality image characteristic that would define Hasselblad's reputation. While relatively unknown compared to later models, the HK7 (Ross) remains an important piece in understanding the evolution of Hasselblad and the development of medium format photography during World War II.
