NIKON DIGITAL 37-80 mm f2.8 ZOOM LENS - $250 (Phoenix)

NIKON DIGITAL 37-80 mm f2.8 ZOOM LENS NIKON 37-80 mm f2.8 RUBIN-1DN FAST FULL FRAME MANUAL FOCUS ZOOM LENS PROTOTIPE You can stumble upon Rubin-1 on the Internet. But this is a completely different lens design. There are no other lenses like this anywhere else. I have two of them, this one a Rubin-1DN for the Nikon cameras and the second one a Rubin-1DC for the Canon EOS EF cameras.  *There are no other lenses like this anywhere else! This rare lens prototype can be used with any Canon Full and APS-C sensor, digital photo or video Nikon cameras. It precisely focused from 1.3 m to Infinity. Its main advantage is that its optical performance, including constant f2.8 aperture, is absolutely unchanged throughout the entire zoom. The lens is absolutely clean, comes with lens caps and neck strap. The camera shown in the photo does not come with this lens. I am an old collector of photographic equipment and this unique lens is from my many years' collection. So if you have a serious interest in this lens and any questions, I will be happy to answer them.
