Here is a very interesting Steinheil Munchen Cassar f3.5 8cm C Mount Cine Lens. I have never seen this lens offered before with a C mount rear so its probably quite rare. The focus and diaphragm work fine. The rear body looks to be a heavy brass. The glass shows wear and could use a good cleaning. I tested the lens out on my Sony NEX and have included a couple shots taken with the lens above. Check out my other auctions for many other cine lenses. Buyer pays shipping and the shipping quote includes insurance.
