Distortion is of equal importance. -- Regards, Eric Stevens |

Much can be fixed (or the effects reduced) in software these days, even in-camera software. -- Cheers, David Web: http://www.satsignal.eu |

Much can be fixed (or the effects reduced) in software these days, even in-camera software. But allowing big geometric distortions which are later corrected in software reduces the resolution in the image parts with lots of geometric distortion. -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

But allowing big geometric distortions which are later corrected in software reduces the resolution in the image parts with lots of geometric distortion. what matters is the end result. by correcting for some aberrations in software and other aberrations in hardware, the end result is will be better than by using only hardware methods. tl;dr it's a good thing. |

So you have to decide if the resolution loss is acceptable. A compromise, like everything! -- Cheers, David Web: http://www.satsignal.eu |
