I'm not entirely sure about this situation, but sensor size numbers often don't reflect an actual measurement of the physical size of the sensor. It's all based on old film standards.
- numpad0 6y agoFractional inches notation is based on imaging tubes, not films. There were of cylindrical fluorescent vacuum tubes that has rectangular imaging area at one end. Inch size notation like 1” or 1/1.2” for CMOS sensors denote size of equivalent imaging tube diameter for its imaging area. “135 full frame”, “APS-C”, “Super 35mm”, “Medium format” on the other hand refers to film sizes, and thus respective imaging area dimensions.
