Finally I have done the calibration for the Canon 15mm lens on a Canon EOS 5d slanted diagonally by 33.7 degrees. The calibration is done for an angle of 60 degrees (i.e. 6 pictures around). I haved used the method described by John Houghton at http://www.johnhpanos.com/epcalib.htm - 3. A DIRECT APPROACH - FOR SLRs ONLY.

The straight line is described by c = 1.629333 -0.1232 * t

The correlation coefficient is r = 0.9998688

This is a very good correlation.

So there are two more calculated values:

Tilt angle (t) | Correction (c) |

7.5 | 0.7 |

5 | 1.0 |

0.0 | 1.65 |

-2.5 | 1.95 |

-7.5 | 2.55 |

-10.0 | 2.85 |

The correlation coefficient is r = 0.9998688

This is a very good correlation.

So there are two more calculated values:

Tilt angle (t) | Correction (c) |

12.5 | 0.09 |

-15 | 3.48 |
