PANOMORPH FUJINON CCTV lens 0.9mm F1.9 (1/3", CS Mount, DC iris type, 360º) Description: this is nice FISH EYE 180º lens, designed for 1/3" CCD or smaller (on bigger sensors this particular lens might work nice due to its super wide angle design). It gives a super-panoramic 360º view, so it is ideal for big CCTV coverage. CS mount only (12,5mm back focus distance). Good for METEOR and UFO work or simply security. Condition: NEW in opened box. No manuals. However, the instruction marks in body are very easy to follow (they allow for fine focus and precise centering of picture in both X and Y axis). I tested it and lens is perfect (iris works as intended when connected to DC 4-pin connector/camera). SPECS according to instruction manual: (see last pic, this is the right column model)
