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?
