LoCA is the least of my concern, in fact LoCA is almost certain for massive apertured lenses. The bigger the aperture, the thinner the DoF and hence more abrupt transition between focal plane and blur regions. This is why LoCA is greatly reduced when you stop down. |

I never bothered removing the internal shroud (to try to achieve infinity) because I never found myself needing any more distance from the lens. This also resulted in the lens being perfectly compatible with unshaved 5D (II) mirrors. |

Indeed, I was wondering the same question after having seen a 24 SSC mod with this option |

The 85L and the 85 SSC aspherical have different coupling desing, as cogitech says. |

max, could you show a picture or a schema of your system? As cogitech is saying, "If you bent the fork legs down too far, they would prevent the focus from traveling back to infinity again". Is it the case in your configuration? I will use either a C/Y adapter, or a M42 one. |

Hi, I did not make pictures during the 85 SSC conversion process. |

m-a-x, cogitech, can you tell me whether the using of a spring is possible as this guy did on a 55/1.2? |

cogitech Registered: Apr 20, 2005 Total Posts: 10909 Country: Canada |
Possible? Probably. |
