CRT Nikkor-O 55mm f1.2 oscilloscope lens

This is another lens designed to record oscilloscope traces on a curved screen. It is optimized for close focusing, about half life-size, and it is extremely sharp at that distance, though it has very strong field curvature (so that the entire trace is sharp ) that makes it look quite strange at longer focusing distances. However, it has a very characteristic bokeh that can be pleasing at closer focusing distances.
