還要注意的是, g28的價錢是那些紅圈鏡的五分之一! |

>這是我以前用EF16-35L大約用28mm的焦距拍的
You are kidding.
Zoom lenses compare with prime lenses?
And Canon zoom lenses is very poor control in 變形.
Try EF24L, EF14L.
even better try FD14L, FD17, FD20, AIS20....... |

FD17 and FD20 are not expensive.
AIS20 is not expensive as well.
EF20 is not expensive as well. |

根據你的論點,
你說"從那些照片中你看不出G鏡變形控制能力",
那麼我就從那些照片中舉出例子, 說明G鏡的變形控制能力,
至於那些FD鏡AIS鏡變形控制能力如何, 都不會影響G鏡的能力,
雖然我沒有驗證過那些鏡, 也不會有那樣的財力,
但我對"G鏡的變形控制比slr鏡好這個論點"十分有信心,
如果你認為這是不對的, 何不post一些相上來讓大家一起研究? |

16-35Zoom vs 28 prime?
forget about it.
Sorry, I really get some kodachrome but not quite possible to scan. |

Your 信心 are almost pure faith. Not much real experience. No need to mention that is also not scientiific at all.
What you need to do is just to believe. No need to take care what I have said or what other people have said. |

RE:新新手
我真不明白如何所一張tilt-up了的相中, 看出極少的變形, 而那jpeg亦只是幾百點而已. 如果要說海岸線為準, 那是一個問題, 因為香港海岸線不是筆直的, 如果你的位置是高於水平線, 而鏡頭對向又不是與對岸的岸線差不多垂直, 拍出來的海岸灣應該見到彎曲, 這是我由海運拍回中環灣仔的經驗, 用的是45鏡頭, 大概在變形上不比Ｇ鏡差吧.
.PS 維港南岸的上環至北角是大至上為內灣, 由海運造高點拍攝, 如果相機水平位置調準, 上環的位置在菲林垂直的較下方位, 北角是較高了, 這是幾何學可計算的在菲林(2D)上應有的海岸線(3D)位置. |

Many people fail to distingulish geometric distortion and other distortion, |

如果在文化中心頂部拍維港海岸線, 會出現類似針氈狀變形, 其實是正常不過. |

No way, digital deform only, not correction, because this is normal 3D->2D shape from coast to film. |

Once upon a time, I have contax G series in my buying list, mainly because size and weight.
However, there were always higher priority item in the list.
Now, I will not invest 135 film stuffs any more. All 135 film items are off from my buying lists except twin P&S cameras for 3D photography.
On my current buying list, there are
Medium/Large format for film and DSLR/DC for 135 or smaller.
What a pity, my beloved Kodachrome is almost dead. |

Thanks. I tried many times with many movement methods with my 612. I used to think it is my skill problem. |
