The GS-1 is superior in terms of design, quality of the lenses and smoothness of function. It’s the biggest of the three lens shutter Bronicas (ETR, SQ, GS-1) The lenses were so good that after this PG Zenzanon line was released Bronica decided to upgrade all of their lenses for the other two cameras as well, using the same technology. It is was released in 1982, shoots a 6×7 frame (or smaller depending on the film back) and there were never any upgrades to this model. The GS-1 is the last SLR ever made by Zenza Bronica. There is something special about any camera when you know that it represents the pinnacle of a given manufacturer’s efforts.
