The IIS is a relatively rare Canon rangefinder camera. It is basically a IIF with added strobe sync. The strobe is an easy modification and so many IIF’s were upgraded. This is why you will find cameras that seem to be IIS’s but the serial numbers are wrong. Or even more puzzling, the load diagram on the bottom will say IIF when the characteristics are IIS.
Another way to view it is that this camera is a IVSB without the 1/1000th shutter speed.
