光刻机镜头我们国家也是能生产的。这个是70年代的，28mm/1.7, 650线对。

This objective was the fulcrum of a special equipment for high resolution micro-lithography which, via direct step and repeat procedure on the silicon wafer, made it possible to create the masks of microchips; these optics, if you will, can therefore be considered as the foundations of all the modern technology, since the applied micro-electronics now manage every aspect and manifestation of our life.

能做这些镜头的国家没有几个。

几只蔡司生产的光刻镜头。右下角的是一只Nikon的光刻镜头。分辨率稍差。

从网上扒点稀有相机的图。

苏联产的ZENIT。

几年来还没见过第二只夜光的东风29钻自动表。 应该算是稀有品种了。

难得一见这么贵的镜头。我正好也有一只。

古董国产表。

1960 年代国产仿Zeiss偏振光显微镜附件，物镜。

当年核工业用的国产显微镜。比较少见。制作相当精良。

老熊，等中国再过20年成了真正的工业强国后，那些早期的工业精品也会成为收藏品的。就像那些精品德国，日本相机那样。

K兄啊，汉莎可真是可望不可得呀！
还是便宜的吧——

Super High End Lens Ultra-Micro-Nikkor

Ultra-Micro-Nikkor lens has the characteristic near an ideal lens. It is not necessary to know the numerical characteristic. Ultra-Micro-Nikkor was once a famous super star, great renown is important, however those survided old lens needs something fun to live.
Ultra-Micro-Nikkor worked very hard in the industry. We have to say "much appreciated" to those lenses.
As we know, Japanese samurai sword was made to kill somebody. However, in those days, the role does not exist now. It just exist as an art. We can feel the Japanese spirit from those swords.

Also, Ultra-Micro-Nikkor can say the same thing.
No one sets this lens to old printing machine again. It is better to use this lens in the Japanese four seasons.
This lens may have a healing power.

The real thing live beyond the years of life on the earth.
This picture as shown is Ultra-Micro-Nikkor 55mm F2. Even it has over 500 lines/mm resolution, the overview is so cute.
The picture was taken at the rice-producing region in early summer.
The Ultra-Micro-Nikkor lens multi coat comes out the grove of the village shrine in Japan.

看看某收藏网站对尼康超微距镜头的赞美之词。

物以稀为贵。 口水。。。。

？？俗的？ 早期日本相机的收藏价格也不低啊。 佳能汉莎旁轴老熊如果有，但是嫌俗的话往这扔啊。

1947年在德国耶拿生产的基辅旁轴。很少见。

配这个灯找了两年——

来点儿俗的吧——

老熊，这是起点相机里的早期款。相当少见。 起点相机总共也不过生产了7万多台。比徕卡M3旁轴少多了。 本帖最后由 Kievuser 于 2015-5-1 19:27 编辑

都是制作精良的金属古董仪器。

迷人的东东。

是否有点像这只国产镜头？1979年产。当年中国的科技人员和工人师傅们追赶先进技术的努力还是很认真的。

细节迷人——

把玩儿的物件儿——
