我没有测试图样,看来只能做实拍了。大家出出主意,看在什么样的环境下拍摄比较
科学及可信? |

测试图只能看分辨率,分辨率在现代镜头的表现中不能算是主要因素,如果用测试图分辨率的微小差异去标示镜头的好坏,会起误导作用,正如photodo.com 。

顾老,
测试图是原件, 有杂志打开两倍那么大, 要用邮寄寄给您, 我没有那么大的扫描仪. |

顾老:
我有一张 Chasseur d'Images 的测试图, 如您需要, 请给我妹儿: [email protected], 我给您寄去. 测试方法是在焦距的20倍(? 我忘了多少倍了, 图上面有说明的, 虽是法文,您可以猜出来的, 倍数指的是135格式, 我想大概是把 图充满画面就是了)上拍. |

You can refer to 摄影家手札.
you need RVP, heavy duty triode, remove any filter, serious focusing and find a well developing shop. From my value view point, the resolution is important but not every thing. Distortion is also important. A suitable contrast is more important than simple resolution. You also need to enlarge both into 16*20 or 20*24 to look the overall feeling. I have experience to shut the group memorial photo with around 600 peoples. equipment 1 is Hass + CF80mm with Agfa ASA50 equipment 2 is Pentax 645 + 35mm with Agfa ASA50 equipment 3 is Linholf 4*5 + Rodenster 150mm All of them enlarge to 16*36. Guess what is the result ? Best is Linholf, runner-up is Pentax 645 |

俺觉得还是拍摄平面物比较合适,比如一面带砖缝的墙。
拍摄时要比两样:一是135和120取景范围都一样,二是120中的一部 分与135的取景范围一样。后者的片子将它剪裁成135格式,然后用 幻灯机一打,结果就出来了。不过这样一比,恐怕120的就不如135 的了,颗粒要比135的粗。 |

太棒了!!!俺已经等不及想看结果啦!
至于您的问题,俺不懂,自己在家里弄过 几个小测试,都不太成功,有的对焦不准, 拍的东西太多。有的看不出区别,拍的 东西太少。有的没摘FILTER。。。嘻嘻, 不好14 |
