中国1950年代就可以生产如此精美的手表了。当时售价差不多相当一两黄金。 ![]() ![]() |

“I want to emphasize that Zeiss was very active in the field of special lenses for industrial use, and although each type has been produced in very limited runs, even just three examples, the sequence of models is much broader than you can imagine; here is a certainly incomplete list of the different models until 2000, namely those easier to classify: S-Planar 45mm f/1, S-Planar 38mm f/1,1, S-Planar 42mm f/1,1, S-Planar 68mm f/1,1, S-Planar 38mm f/1,2, S-Planar 42mm f/1,2, S-Planar 46mm f/1,2, S-Planar 60mm f/1,3, S-Planar 65mm f/1,3, S-Planar 37mm f/1,4, S-Planar 41mm f/1,4, S-Planar 75mm f/1,4, S-Planar 69mm f/1,5, S-Planar 125mm f/1,5, S-Planar 14mm f/1,6, S-Planar 25mm f/1,6, S-Planar 31mm f/1,6, S-Planar 50mm f/1,6, S-Planar 40mm f/1,7, S-Planar 0,1mm f/2, S-Planar 210mm f/2, S-Planar 95mm f/2,1, S-Planar 100mm f/2,8, S-Planar 14mm f/3,3, S-Planar 48mm f/3,9, S-Planar 32mm f/4, S-Planar 60mm f/4, S-Planar 74mm f/4, S-Planar 135mm f/4, S-Planar 195mm f/4, S-Orthoplanar 50mm f/4, S-Orthoplanar 60mm f/4, S-Planar 0,4mm f/5, S-Planar 0,42mm f/5, S-Planar 0,43mm f/5, S-Planar 0,48mm f/5, S-Planar 32mm f/5,6, S-Orthoplanar 105mm f/5,6 ed S-Planar 60mm f/8: really a comprehensive and varied series indeed, ranging from lenses for microfilm (S-Planar and Orthoplanar 50mm f/4, 60mm f/4 and 105mm f/5,6) to those for laser medical (the very short focal lengths) to those designed for microlithography of microchips; precisely the larger models in this category, which also includes the S-Planar 25mm f/1,6 just discussed, reached impressive prices, even 500,000 DM of the time!”
网上搜到的关于蔡斯工业头的资料。 其中提到一只S-Planar 25mm f/1.6的价格当年竟然高达500,000德国马克! |

Kievuser 发表于 2013-9-4 20:20 你发的图片是一老外的东西。上一个我收藏的同系列的CARL ZEISS JENA DDR DOKUMAR 5/35,注意看镜头编号是4位数,字体也是全部大写的,产量非常稀少,这是前苏联※※定制的,镜身全部黄铜非常沉,小小的镜头重量竟然比尼康18-105还沉。民用版本就是铝合金很轻的了,而且编号是8位数。 本帖最后由 卡卡猪 于 2014-5-16 21:12 编辑 |
