Excerpt from the Canon Boot Camp Manual
Canon developed the 5D’s sensor to replace 35mm still photography film, which measures approximately 37 x 24mm (the size of a VistaVision frame). They were successful.
35mm film runs through a still camera horizontally. The frame size is approximately 37 x 24mm. That’s the size of the Canon 5D sensor.
35mm film runs through a movie camera vertically. The frame size is approximately 22 x 16mm. That’s the size of the Canon 7D sensor and the Panasonic AF 100 and many others.
Here is a comparison of the Canon DSLR 5D, 1D and 7D sensor sizes.
