Carl Zeiss Jena Biotar 5.8cm f2 Sample

I wrote about this "castrated" Carl Zeiss Jena Biotar 5.8cm f2 lens some time ago, before mirrorless cameras were on the market.  I thought the lens was history, but it is rescued by the mirrorless cameras, especially the NEX-6. I have it remounted on the Yeenon helicoid and the focusing feels a lot better. There is a benefit for mounting the lens on the helicoid: the lens could be used almost like a macro lens.
