The “G” in the camera designation stood for “Grade Up” which referred to the quality improvement. The “III” indicated the third-generation Canonet series, following the original Canonet and the New Canonet.

The basic specifications were the same as the New Canonet QL17’s. Checking the battery was easier with a battery check button on the side of the viewfinder eyepiece. A lamp would light when the battery was still good.

Manufactured from spring 1972 to summer 1982, it was a long-selling bestseller over 11 years. About 1.2 million units were made.
