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 20D Astrophotography | 80 mm Canon APS-C sensor Crop factor/focal length multiplier by * 1.6 |
| Canon EOS D30 | 80 mm Canon APS-C sensor Crop factor/focal length multiplier by * 1.6 |
** Experienced focal length when using a lens such as a common "50mm f/1.8"
