Ultra-Micro-Nikkor 28mm F1.7e

One of the more fantastic and rare lens for the Ultra-Micro-Nikkor series.
The Ultra-Micro-Nikkor 28mm F1.7e consisted of ten elements set in a heavy weight and black painted plain barrel with L39 Leica thread. We called "Black Cylinder".
The Ultra-Micro-Nikkor 28mm F1.7e used 40.5 mm accessories. A Nikon 40.5 mm reversing adapter is just fit to her.
You can see very beautiful and mysterious red coating on the lens.
