For sale are two very rare 135mm f2 Xero-Nikkor lenses. Both lenses are optically flawless and come with both caps and the original flange. One lens is near mint cosmetic condition while the other has a few scratches and scuffs on the lens barrel.
Lens specifications according Red Book Nikkor (http://redbook-jp.com/redbook-e/fan11/a05.html):
"The Xero-Nikkor is designed expressly for reproduction of CRT traces on the 127mm (5-inch) diameter screen of the Charactron Tube.
It can also be used, of course, with an osilloscope or any other CRT.
Its hight speed of f/2 affords adequate exposure of the high framing speeds of the relatively low-light level traces on the CRT.
Standard magnification ratio is 2X at which corrections are optomal, but aberrations remain well corrected from 1.5X to 2.5X.
Vignetting is insignificant in CRT reproduction applications.
Resolution is comparable to or better than that of the CRT tubes encountered in practice.
Color correction is 400 nm - 650 nm.
The lens is thereaded at both ends for convenience in normal or reversed mounting."

I think these lenses have a lot of potential as excellent macro lenses or even general purpose lenses. I would love to mount them and use them on my 4x5 Horseman but I just don't have the time to play around with lenses right now and I am not that interested in macro photography. If it takes me awhile to sell them, I might keep one copy to play with when I do have time (in the hopefully not too distant) future.
I am asking $550 o.b.o. for the lens in near mint condition and $500 o.b.o. for the lens with a few scuffs.
