The first model, the RB67
Pro, came out in 1970 and was made until 1974. They made some changes
in it, renamed it the RB67 Pro-S and was produced until 1990. In 1990
they made further changes and renamed it the Pro-SD.
The RB is unique in that
it has a revolving back (RB = Revolving Back, get it?). This allows
you to quickly switch between portrait and landscape orientations. This
would otherwise require a cumbersome flip of the camera body and since
the camera weighs 3 tons (in reality, 6 pounds), the RB feature is much
appreciated.
I love using
this camera - Links to a few examples:
