Many people wonder what calibration board size they should use. Make sure your calibration board is 1/3 of the camera's live view.
If you are using the lenses that came with the system, the required calibration board sizes are as follows:
| Field of View (FOV) | Calibration Board Size |
| 200 mm | 7 mm |
| 400 mm | 15 mm |
| 600 m | 25 mm |
