Unknown lens (PENTAX probably) (around F1.8 and 10-140mm) 1/3" C mount Description: This lens is a high end CCTV lens, but I don't know brand. Seems Pentax quality and sturdiness. I used it for a while in my observatory set up because it is VERY sharp lens, very well built. Unfortunately it is not very fast, around F1,8 I calculate, so that's not so good for my purposes. Again, this is an incredible lens, but it has to go to fund other projects. Focus and zoom motorized (as always, you apply 5-16v and motors rotate (yellow cable is common), and the other two cables are zoom and focus. If you reverse voltage, they go the other way round. This is SUPER clean with no fungus, haze or inner dust at all! I would also say this is around 10-140mm lens. The only thing sure is C mount and 1/3" size compatibility. Issues: usage marks, a couple of nicks in front lens, but nothing else. Performance I would say it is 99,5% as new.
