This successor to the IV Sb had an aura of top quality and precision. After the shutter was released, the shutter speed index mark on the fast shutter speed dial indicated the shutter speed. On the dial, the shutter speed settings increased in two-fold increments, making it easy to use. The base of the film advance knob also had a reminder for the film's number of obtainable exposures.
The IV-series peaked with the IV Sb and IV Sb2. It was during Canon Camera's golden age. Along with the Nikon S, these two cameras demonstrated Japan's prowess in camera technology.
