[Canon] IV S (IV F) | Film Cameras | January 1952
This camera was Canon's first model to feature an all-diecast chassis. Initially named the IV F, it was later renamed the IV S. It incorporated the same film advance and rewind knobs, as well as the single-piece viewfinder mode selector lever, which were first introduced with the Canon III A. These design elements significantly improved usability and durability. The IV S represents an important shift in Canon's history, laying the groundwork for advanced photography and is regarded as one of the key models in the brand's evolution.
