Ernitec Japan CCTV ULTRAFAST F0.95 meteor astronomy motorized autoiris lens Description: This lens is a high end CCTV lens super to use in astronomy and low light conditions. You appply 12v (or less) at yellow/red cables to move zoom (reverse polarity to go the other way), and the same for focus on black/white cables. Iris is AI type ("on lens" videoiris), and it works nice. I can remove it for you (including the light detector window) FOR FREE if you plan to use non-auto iris camera (not complicated, about 30' work). Let me know before shipping, please. Issues: usage marks, there is a bit of haze behind front lens due to breathing but it is minimal (you really have to look for it under strong light scrutiny) and I would say this lens gives out 95/100 performance. Technical information for astronomy/meteor work: this lens is designed for 1/3" BUT IT WORKS with MINIMAL vignetting in 1/2" sensors (none at max and min zoom, VERY little in the middle zoom range). I tested it on Sony ICX039 old sensor, so it could very well be all you need for meteor work with 1/2" and smaller sensors.
