有一些英文资料,图片上镜头的编码是两位数,至于文字说明,看谁能懂,帮忙翻译一下----
An interchangeabie cover can be screwed on the viewing window.
about 50 or so stereo-FEDs were produced .
erroneously dated as 1948,a period in which FED had much difficulty in producing basic lenses in a factory being rebuilt.
in any case incomplete,since it was not accompanied by prisms for a base enlarger.
this lensn,like certain"false FED-Leica,s" ,becomes a rare collector,s piece. |
