PopPhoto在30年前对海鸥单反的评测# PhotoGear - 摄影器材
p*p
1 楼
近日翻看杂志，偶然看到一篇80年左右Norman Goldberg的文章，把一台从中国带回的二
手海鸥单反（应该是DF-1早期版）大卸八块，做了一番细致的评测，目的在于考察神秘
的红色中国35mm单反相机在世界摄影器材界的地位。
作者本以为这台Minolta卡口的单反最多也就相当于日本50年代的工艺水平。随着拆卸的
进行，作者逐渐对这台中国相机有了进一步的认识。"Externally, its satin-chrome
finish is fairly good". "The main casting is intricate, thick-walled, stron
g and reasonably well machined". "There are many parts made of steel…, and
most of these were well heat-treated, being used for tasks requiring good ha
rdness and/or stiffness." "The shutter-speed-regulating mechanism is especia
lly well done at the high-speed end." "The shutter curtains and their tapes
are as good as those being made anywhere today." "What struck me most about
the insides of the Seagull was the large number of shim washers used to redu
ce the end-shake … Additionally, nearly every critical function was nicely
adjustable. This kind of fussiness deserves respect."
作者对相机带的单膜套头58mm f/2镜头也做了一番评论。他对此头的中心解像力非常满
意。全开时有一定的像散和边缘慧差，但收到f/5.6以后，整个像场范围内都非常锐利。
在文章的最后，作者认为"There is no question in my mind that China will be a
growing factor in this highly specialized field." 并用了这样的一段话作为结语
nland, and he(she, it) is stirring."
