Rainbow 12mm F1.2 "E" vintage CCTV lens Description: this is nice quality cctv lens. It has weird 4 pin cable for Auto iris connection to camera. Unfortunately I don't have more info about it at this time. It has ALC and LEVEL knob controls. Focusing is made through rear ring. Not sure if CS or C mount... if you are interested, let me know and I can test it. Condition: old stock. It has a small nick at the focusing ring, but it works good anyway. Lenses seem new. Seems "old stock", lens never used (no box and some cosmetic issues).
