The Haselblad 500C (the model 500CM is merely a slightly updated version of this camera), was the first successful 6x6 negative camera Single Lens Reflex System Camera ever devised that used leaf Compur shutter, synchonizing shutter with electronic flash at all shutter speeds. From the onset,It was intended to fill a void that Victor Hasselblad and company saw in the camera market during the late fifties the last century.It was also intended to be quite simply, "the best Camera ever produced".
Many photographers would agree that 500C achieved this goal. It changed photography forever. It was also the clear choice of the astronuats and the 500C as well as subsequent models were used during the Appolo Moon Mission. An electricly-driven model, and another sister model was even used on the moon's surface itself.=The things I like most about the Hasselblad 500C are as follows:1)It was engineered by Hasselblad, with the help of the famous car makers at Porche, to be very ergonomic.In my hands,it has always felt very natural, with all the controls falling exactly in place, or within easy reach. For those who may feel differently, I submit that they may not be using it as intended.
For so many things times have changed greatly since 1958, but most of the mechanics of film cameras are still the same. However some of the routine techniques used then, have been lost on later generations.
