- 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.
