Sensors / crop factor

Both these cameras have the same sorts of sensor (called "Canon APS-C") which means that if you compare these cameras side by side the lenses will also have the same experienced focal length. Neither of the cameras has a Full frame sensor which means that you will get a "crop factor" where the camera's sensor size affect the focal length with a multiplier.

Camera Focal length, 50mm f/1.8 **
Canon EOS 400D 80 mm
Canon APS-C sensor
