- QL stands for Quick Loading, a clever system that makes loading film fast and foolproof
- 17 refers to the six-element 40mm f/1.7 lens, highly praised for its “Leica-like” sharpness and ability to focus as close as 2.6 feet
- G means “grade up” and recognizes quality improvements over the earlier Canonet QL17
- III represents the third (and final) generation of Canonets
Secondly, although it’s often dubbed the “Poor Man’s Leica” this is a fantastic little camera which can stand shoulder to shoulder with much more expensive rangefinder cameras. The Canonet GIII QL17 was Canon’s best-selling camera for over 11 years, and is the world's top selling rangefinder (with inbuilt light meter) a record unlikely to be broken.
