A medium format single lens reflex camera introduced in 1970 by Victor Hasselblad AB in Göteborg, Sweden. 120mm rollfilm camera. This model is one of the later models in Hasselblad’s V-System, a wildly popular camera system that boasts a wide variety of modular parts like viewfinders, film backs, cranks, and, of course, lenses. The 500 C/M is based on the original 500 C from the late 1950s: the first of many modified Hasselblad cameras to be taken into space by NASA astronauts.
