fsmyth 0 Posted November 5, 2006 The lens is labeled: Vicon Industries, Inc. Model V18-108M-3 000-00 Prod. Code: 1407 The mounting ring, which is almost flush with the end wall, measures 43mm, as close as I can measure. There is a 7/8" round tube protruding out about 3/4", with a tiny lens and about an 18mm female threaded ring holding it in. The main lens is labeled "Apollo MC TV Lens, 1:1.8 18-108mm No. 790052", and is approx. (not quite) 3" in diameter. The web seems to have never heard of this lens. My question: is the mounting ring 42mm or 43mm, and what do I need to adapt it to a "C" mount camera? Share this post Link to post Share on other sites
